Remove hours and minutes from dates in one step - excel

I always get the dates like shown in Column A, but I need them as shown in column C. How can I do it without having to create column B helper? I need that because the hours and minutes mess up what I want to achieve after this.
Column A
Time with hours and minutes:
22/05/2015 14:57
11/06/2015 15:40
28/05/2015 08:27
26/05/2015 14:51
25/05/2015 14:18
25/05/2015 15:51
Column C
Time without hours and minutes:
22/05/2015
11/06/2015
28/05/2015
26/05/2015
25/05/2015
25/05/2015
I managed to solve this by creating a column B that converts to text
=Text(A2;"DD-MM-AAAA")
and then column C converts text to value
=Data.value(B2)
While this process works, it causes me a lot of unnecessary data and I wonder if I can do this automatically with a vba-excel macro in one step. I also want the number dates in column C always equal to the number of dates in column A and dates in the same order.

To get the date only use:
=INT(A2)
And format to date. This works because dates in excel are the number of days since December 31st, 1899 so for example May 10th, 2016 is 42500 days since.
And the Time is a decimal based on 24 hours. So, May 10th, 2016 12:00:00 equates to 42500.5.
So to get just the date we remove the decimal. INT() does just that.

This was tagged with [excel-vba] so I'll offer a full column time stripping solution.
The Range.TextToColumns method makes quick work of stripping off the date portion of a datetime. The fieldinfo parameter can specify the DMY format you are using and discard the time portion with the appropriate xlColumnDataType. While most TextToColumns commands are made 'in place', an alternate destination is available if specified. When specifying an alternate destination, the original data is left intact.
Option Explicit
Sub stripTime()
Dim i As Integer
With Worksheets("Sheet1")
'check to see if A1 is a date or a column text label
i = Abs(Not IsDate(.Cells(1, 1).Value))
With .Range(.Cells(1 + i, "A"), .Cells(.Rows.Count, "A").End(xlUp))
.TextToColumns Destination:=.Cells(1, "C"), DataType:=xlFixedWidth, _
FieldInfo:=Array(Array(0, xlDMYFormat), Array(10, xlSkipColumn))
'optionally assign a custom number format
.Offset(0, 2).NumberFormat = "[color10]dd-mmm-yyyy_)"
'optionally autofit the column width
.Offset(0, 2).EntireColumn.AutoFit
End With
End With
End Sub
After processing you are left with your original datetimes in column A and true date-only values in column C.
         

you can use =Today() OR =NOW() then change

10-04-2020 3:09:42 PM transforms to 10.04.2020
Using this formula:
=IF(ISBLANK(A1),"",TEXT(A1,"DD.MM.YYYY"))

VBA range.find finds wrong date value

I am looking up a price multiplier for a given date in an Excel sheet, but range.find gives the wrong date. Here are the relevant code snippets:
If Not IsWbOpen("daily_prices.xlsx") Then
Workbooks.Open "C:\.....\daily_prices.xlsx"
End If
Set daily = Workbooks("daily_prices.xlsx").Sheets(1)
daily.Range("A:A").NumberFormat = "dd/mm/yyyy"
End If
This part makes sure that the column A:A, which contains the dates, is formatted correctly.
The code then loops through a date range where d is a date between d1 and d2. In my test script, d1= Jan 1, 2023 (formatted as "01/01/2023"), and d2 = Jan 30, 2023 (formatted as "30/01/2023").
The Excel sheet "daily" has a header in row 1 and 49 different dates in column A, ordered chronologically from "11/01/2023" to "01/01/2024", and the related multiplier (k), starting in row 2.
Only the dates that have a multiplier defined are present in the sheet. The first group of dates is from "11/01/2023" at row 2 to "22/01/2023" at row 13, the next starts with "17/02/2023" at row 14, and so on. Dates in between have no multiplier, and thus are not present.
I search the multiplier with this part of the code:
Set c = daily.Range("A:A").Find(what:=d, After:=Range("A1"), LookIn:=xlValues) 'is this date in the daily prices?
If Not c Is Nothing Then
k = CDec(daily.Cells(c.Row, 4)) ' multiplier is in column 4 (D:D)
rate = rate * k
End If
As expected, c is NOTHING for all dates below "11/01/2023". When d = "11/01/2023", c becomes "not NOTHING" but strangely it returns "11/11/2023" instead of "11/01/2023", which is in row 40 instead of row 2, thus it fetches the multiplier of row 40 instead of row 2.
I have re-checked all the code after reading several similar cases and made sure that column A is formatted correctly as "date", but I still get "11/01/2023" wrongly 'found' at row 40 instead of row 2, and the value returned is "11/11/2023" instead of "11/01/2023".
Instead of "12/01/2023", it finds "31/12/2023", and instead of "14/01/2023", which is part of the dataset, it finds nothing.
What did I overlook, where is the error?
Eventually, I found the solution.
It appears that using dates formatted as dates leads to ambiguity with Range.Find(d) as it's very similar to a text search, and depending what date format you use, their partial strings (month and day) may create confusion in certain language versions of Windows. I noticed this when I was looking for a date with day=11 or 12 and found a date with month=11 or 12. This is typical for the confusion that occurs sometimes when you use data formats like "mm-dd-yyyy" (US) and "dd/mm/yyyy" (other) and looks like a Windows bug to me. Windows should distinguish the two formats clearly, but sometimes it doesn't.
There was a similar problem at VBA Range.Find method not finding a value that IS in the range that helped me find the solution.
I needed to format the search object temporarily as numbers
daily.Range("A:A").NumberFormat = "0"
and also search for the long integer value of the running date, thus the starting value is
d = CLng(date1)
where d is type number and date1 is type date. The search term is then simply
Set c = daily.Range("A:A").Find(d)
If Not c Is Nothing Then ...
At the end I reformat the date column with
daily.Range("A:A").NumberFormat = "dd/mm/yyyy;#"
This resolved the problem.
Thank you all for your kind help.
#Ron Rosenfeld's hint came closest as he proposed to search for What:=CDbl(date), which is what I am basically doing, except that I prefer CLng over CDbl as I need the date as an integer and not as a floating point number. The only problem with that idea was that you cannot search for .value2. You can only search for xlValues (which is not the same) or xlFormulas. Neither would find this long integer number in the cell's properties.
Transforming both the search object and the search item to numbers resolves the ambiguity completely.

Getting Current Date and Return as Integer?

I have a date like this (mm/yy) in row 1
A B C D E F
1/19 2/19 3/19 4/19 5/19 6/19 ...
I want the VBA to recognize today's date and match it to current column and return as integer.
Ignoring the days (only matching month and year).
For example, if today is 4/13/2019, it would be 4 (column D)
I would need this in VBA because I will be using it to define a range:
For today To x month
It appears OP was looking for a VBA solution, so here is an alternative.
I can think of a few completely different methods of accomplishing this within VBA. Your question isn't very clear of what you are wanting the end result to be, but it appears you are looking for a function that will return the column number - perhaps so you can use to pinpoint a range.
Function DateCol(ByVal InputDate As Date) As Long
Dim colDate As Date
colDate = InputDate - Day(InputDate) + 1
Dim srcRng As Range
Set srcRng = ThisWorkbook.Worksheets("Sheet1").Rows(1)
DateCol = srcRng.Find(What:=colDate, LookAt:=xlWhole).Column
End Function
You simply take an input date, subtract the days (and add 1 since the first day of the month isn't 0). Then you take this new date and use the .Find() method to locate the range that contains your date on the worksheet, and finally the .Column property to get the number you are looking for.
Here is a small sample usage:
Sub test()
' Example Usage
Cells(10, DateCol(#6/11/2019#)).Value = "Test"
End Sub
In the above test sub, the DateCol() function would have returned the value of 6 in your sample worksheet, making the result:
Cells(10, 6).Value = "Test"
Only issue is that this function doesn't contain any error handling. You will raise an error if the date is not found in .Find(), so ensure that you take this into consideration.
Also, don't forget to change this line to use the true Worksheet:
ThisWorkbook.Worksheets("Sheet1").Rows(1)
I had to redo my answer after messing with the data. this is what i ended up with.
On Row 1 I entered the dates as: 1/1/2019, 2/1/2019, 3/1/2019... and custom formatted the row to only show it as mm/yy.
With the formula below I grab the month and year from the given date and convert it into the first of the month. I am very positive there is a better way to make it but my brain is fried for the day.
=MATCH(NUMBERVALUE(TEXT(A3,"mm")&"/1/"&TEXT(A3,"yy")),$1:$1,0)
Edit: (Edit formula to make it permanent on Row 1 [$1:$1])
Assuming that the date 4/13/2019 is on Cell A3

converting 'mm/dd to dd/mm/yyyy

I've got a whole column of 1000+ entries in excel that has the date keyed in as '01/02, '01/03, '01/04... representing Jan 02, Jan 03, Jan 04 and so on as the person was trying to maintain a mm/dd format while saving on the column width.
This has become somewhat troublesome since the entries are all strings instead of dates and I need to input years in now to get dd/mm/yyyy.
Does anyone know how to go about doing this (other than of course manually changing each of the 1000+ entries?)
Also, I would appreciate it if you can share how I can possibly show dd/mm while retaining dd/mm/yyyy on the entry in excel?
Thank you so much for looking at this.
While 393 rows is not an excessive amount of data, you should find that bulk processing is much faster than looping through rows and processing each cell.
Sub Date_Conversion()
With ActiveSheet
With .Columns(1)
.TextToColumns Destination:=.Offset(0, 4), DataType:=xlFixedWidth, FieldInfo:=Array(0, 3)
.Offset(0, 4).NumberFormat = "mm/dd;;;[red]#"
End With
End With
End Sub
As no year was provided for any of the cells, the default is the current year. Any text value that was not processed will be formatted in a red font and left-aligned.
If you wanted to simply replace the existing data in column A, replace .Offset(0, 4) with .Cells(1).
In column 1 let's say you have the dd/mm. In the next column, label that DD and in each cell put
=DAY(A2)
Where a2 is the target cell. Do the same in the next column labelled MM. Create another column labelled YYYY and put the year you want. Then one last column labelled mm/dd/yyyy and put this formula
=CONCATENATE(D2&"/"&C2&"/"&B2)
Long work around, but will get you what you want.
Since the date is represented by a string in the format mm/dd you need to first manipulate the string to get it in a day format:
You can use the below:
=DATEVALUE(RIGHT(CELL,2)&"/"&LEFT(CELL,2))
(replace cell with the address of the cell that you want to change(
Once you have done this to show dd/mm:
Select the cells that you want to format and:
Right Click / Format Cells / Custom
and type in the inputbox dd/mm
Hope this helps.
So I finally fixed it and this charm of a code did the trick! Wanted to share with you guys!
Sub Date_Conversion()
For i = 1 To 393
m = Mid(Cells(i, 1), 1, 2)
D = Right(Cells(i, 1), 2)
Cells(i, 5).NumberFormat = "mm/dd;#"
Cells(i, 5) = DateSerial(2015, m, D)
Next
End Sub

Date format dd/mm/yyyy read as mm/dd/yyyy

I have a spreadsheet with a column formatted as:
Category: Date
Type: *dd/mm/yyyy
Location: UK
When I read the data in this column via VBA, it reads in the format mm/dd/yyyy.
For example, 10/06/2014 (10 June 2014) is reading 06/10/2014 (06 Oct 2014).
My code: sDate = SourceSheet.Range("AB" & CurRow.Row).Value
I have this issue with my forms too and the best method for me is to format the textbox like this:
sDate = format(SourceSheet.Range("AB" & CurRow.Row).Value, "mm/dd/yyyy")
Even though the date format is wrong in VBA, it seems to work the right way round in Excel. It's weird, I can't explain why it happens, but this fixes it for me. Whenever I go from VBA to Excel, I almost always find this issue if the value is stored as a date.
Consider:
Sub luxation()
Dim sDate As Date, CurRow As Range
Set SourceSheet = ActiveSheet
Set CurRow = Range("A1")
ary = Split(SourceSheet.Range("AB" & CurRow.Row).Text, "/")
sDate = DateSerial(ary(2), ary(1), ary(0))
MsgBox Format(sDate, "dd mmmm yyyy")
End Sub
This question of mine - .NumberFormat sometimes returns the wrong value with dates and times - gives some background which may help.
I first encountered this VBA bug many years ago and it is worse than it seems. I noticed that many - but not all - dates in a worksheet that I had been updating for a year were wrong. It took me a long time to diagnose the problem. Those dates that could be interpreted as middle endian dates had been corrupted but those that could not be interpreted as middle endian dates were unchanged. So 12/06/2014 will become 6 December but 13/06/2014 will remain 13 June. If 13/06/2014 had been rejected as an invalid date or left as a string, I would have spotted the error immediately. The dual interpretation so every date was imported as a date - the wrong date but still a date - ensured I did not notice until much later maximising the cost of correcting for the bug.
Excel holds dates and times as numbers. "17 June 2014" is held as 41807 and "1 January 1900" is held as 1. In both cases, the value is the number of days since 31 December 1899. Times as held as a fraction:
number of seconds since midnight
--------------------------------
seconds in a day
So 06:00, 12:00 and 18:00 are held as 0.25, 0.5 and 0.75.
This bug is encountered when the transfer of a date involves a conversion to and from string format. I have not discovered a single case in which the conversion from date to string has been wrong. It is the conversion from string to date that hits this bug.
I can see that SilverShotBee's solution will avoid the bug but it would not appeal to me. I no longer use any ambiguous dates ever.
One choice is to transfer the value as a number. If cell A3 contains the date and time "17 June 2014 9:00" then CDbl(Range("A3").Value) returns 41807.375. When you store this number in a cell you will need to set the cell's NumberFormat to the date format of your choice but that might be a good thing.
If I were going to use middle endian dates, I would be explicit. #13/06/2014# is always interpreted as middle endian.
I prefer unambiguous strings. "2014-06-13" or "13 June 2014" are not misinterpreted by VBA or by a human reader.
Have just come up against this issue! Reading records from a .csv and storing in an .xls
I found the following sequence works to overcome the misinterpreted dates:
Read the date field from the .csv file
Store it into a cell in the .xls file
Read it back into vba
Store into its required destination in the .xls
Date is in original format
I found this issue to be incredibly complex and was trying to keep it as simple as possible but have indeed left a few vital details out! Apologies. Here is a fuller version of what I found:
First of all I should explain I was reading dates (and other fields) from a .csv and storing back into an .xls
I am on Office 2002 running on Windows/7
Using 2 example dates: 27/4/2015 and 7/5/2015 in dd/mm/yyyy string format (from the csv)
What I found was:
Reading the 27/4/2015 text date field from csv into a variable dimensioned as STRING and storing into an xls field in dd/mm/yyyy DATE format produces a cell that reads 27/4/2015 but converting it into a cell formatted as Number also produces 27/4/2015. 7/5/2015 on the other hand produces a string that reads 7/5/2015 and converting it into a cell formatted as Number produces 42131.
Reading the 27/4/2015 text date field from csv into an undimensioned variable and storing into an xls field in dd/mm/yyyy DATE format produces a cell that reads 27/4/2015 but converting it into a cell formatted as Number also produces 27/4/2015 while 7/5/2015 reads 5/7/2015 and converting it into a cell formatted as Number produces 42190.
Reading the 27/4/2015 text date field from csv into a variable dimensioned as DATE and storing into an xls field in dd/mm/yyyy DATE format produces a cell that reads 27/4/2015 and converting it into a cell formatted as Number produces 42121. 7/5/2015 on the other hand produces a string that reads 5/7/2015 and converting it into a cell formatted as Number produces 42190.
The first 3 scenarios above therefore do not produce the desired results for all date specifications.
To fix this I do the following:
Input_Workbook.Activate
ilr = Range("A5000").End(xlDown).End(xlDown).End(xlDown).End(xlUp).Row
For i = 1 To ilr
Input_Workbook.Activate
If IsDate(Cells(i, 1).Value) Then
d1 = Cells(i, 1).Value
d1 = Replace(d1, "/", "-")
ThisWorkbook.Activate
Cells(14, 5).Value = d1
d1 = Cells(14, 5).Value
If VarType(d1) = vbString Then
d1 = CDate(d1)
End If
Cells(i, 1).Value = d1
End If
Next
The cell used to store the date initially is formatted GENERAL and the ultimate target cells is formatted as DATE (dd/mm/yyyy).
I don't have enough brain cells left to fully explain what happens to the dates during this process but it works for me and of course the choice of target cells is completely random in the above code block.
The problem was VBA was opening the csv with the reverse dates for single digit days.
This way of opening the workbook worked the same as when I did it manually so had the correct dates in dd/mm/yyyy format. Then copied across correctly:
Workbooks.OpenText FileName:=fpathO, datatype:=xlDelimited, comma:=True, local:=True

EXCEL VBA CSV Date formatting issue

I am an Excel VBA newbie. My apologies if I am asking what seems to be an obvious question.
I have a CSV text file I am opening in an Excel worksheet. One row of the file contains date information formatted as "YY-MMM', (ie: 9-FEB, or 10-MAY). When the Excel spreadsheet opens the file the date information is changed to "mm/dd/yyyy" format and reads as 02/09/2009 or 05/10/2009 where the YY-MMM is now MM/YY/2009, (ie: the 9-FEB becomes 02/09/2009, and the 10-MAY becomes 05/10/2009).
I would like to know if it is possible to reformat the field from YY-MMM to mm/01/yyyy.
I have tried to parse the date field after converting it to text with
Range("B11", "IV11").NumberFormat = "text"
However, then the value is a serial date and non-parsable.
I have been unsuccessfully looking for a list of the NumberFormat options.
If you can point me in a direction it will be much appreciated.
Just to answer a part of your question, here is the list of date formatting options (excluding time):
d = day of month, e.g. 7
dd = zero-padded day of month, e.g. 07
ddd = abbreviated day name, e.g. Thu
dddd = full day name, e.g. Thursday
pretty much the same for month...
m = month number, e.g. 7
mm = zero padded month number, e.g. 07
mmm = abbreviated month name, e.g. Jul
mmmm = full month name, e.g. July
years are simpler...
yy = 2 digit year number, e.g. 09
yyyy = 4 digit year number, e.g. 2009
you can combine them and put whatever separators you like in them
e.g.
YY-MMM, 09-FEB
DDDD-DD-MMM-YY, Wednesday-04-Feb-09
dd/mm/yyyy, 04/02/2009
mm/dd/yyyy, 02/04/2009
I've just been trying a few things out and I think your best bet is to change the format in the text file to conform to a more standard date arrangement. If you can reverse them (e.g. MMM-YY) you'll be fine, or split them into separate columns (what if when you import you define - as a separator as well as comma?). This is one case where Excel trying to be clever is a pain.
HTH
If you are currently using File > Open to open the CSV file then try Data > Import External Data > Import Data instead. This brings up the text import wizard which might give you more flexibility in how to import the file. Specifically, it lets you declare a column in the file as being text so that Excel does not try to parse the value
As Simon has explained, your terminology for the current date format is not correct. 9-FEB corresponds to d-mmm format and 02-19-2009 (NB deliberately changed to an unambiguous date for this example; 02-09-2009 is 9th Feb in the US but 2nd Sept in the UK) corresponds to mm-dd-yyyy
If you wanted to change the NumberFormat to text for the range starting in cell B11 and ending in cell IV11 then you would use:
Range("B11:IV11").NumberFormat = "#"
# signifies text format and you need the : operator to indicate a contiguous range of cells. Your original example of Range("B11","IV11") actually indicates the union of cells B11 and IV11 and thus would only have affected two cells
It is unusual to have your data structured in rows rather than columns. Rather than having your dates in row 11, it would be more common to have them in column K instead so that you would use Range("K2:K65535") or just Rows("K") Most of the built-in Excel stuff like Sort and AutoFilter assume that your data is laid out in columns anyway. Row 1 traditionally contains the column names and then each subsequent row contains an individual record. You might want to look at how your CSV file is being generated to see if you can switich it to a more usable column-based structure
If you have a date like 19-FEB as text in a cell then, assuming that you always want the year part to be the current year, you can change it to the first day of the month in mm/dd/yyyy format in VBA. This example only changes one cell but you can use it as the basis for a wider solution:
Option Explicit
Sub main()
Dim strOrigValue As String
With ThisWorkbook.Worksheets("Sheet1").Range("B11")
strOrigValue = .Value
.NumberFormat = "mm/dd/yyyy"
.Value = DateSerial(Year(Date), Month(strOrigValue), 1)
End With
End Sub
DateSerial creates a date serial number from the given year, month and day. Year(Date) extracts the year part from the current system date, Month(strOrigValue) takes the month part from the data that's already in the cell and we want the first day of the month
In order to read in a date, you can do something like this:
myDate = DateValue(dateText)
although there are caveats to how excel may interpret dates, and what technical limits it has in what dates it may store. (you may need to read up on maximum and minimum dates, and how excel interprets two-digit years >30 vs <30, among other things)
In order to format the date, you can use one of three functions:
myDateText = DatePart("yyyy", myDate) & "/" & DatePart("mm", myDate) & "/" & DatePart("dd", myDate)
or this
Format (myDate, "yyyy/mm/dd")
or this
FormatDateTime(#1/1/2020#, vbShortDate)
You can search google for more documentation on each function. For the format function, you will want to find a good reference -- I've seen some rather incomplete ones. MSDN tends to have good ones, but not always. Feel free to bump this answer if you want more details.
This assumes your 2 digit year is 2000. Once you end up with your incorrect date 9-Feb = 02/02/2009, you can convert this to the date you want with the formula: =DATE(Day(B11)+2000,Month(B11),1)
