Excel- counter for every hour - excel

I have some dates with time in my excel sheet, i was just wondering if there was a day to have a counter for each time it occurred in that hour. For example,
01-Jan-2015 05.04.18
01-Jan-2015 05.55.24
01-Jan-2015 06.01.45
02-Jan-2015 09.11.32
So there is 2 occurrences in the 05 hour of 1st Jan, 1 occurrence in 06 hour etc.
I would count it manually but there are over 10,000 lines.
Any idea how I could use a formula to set a counter, would I use COUNTIF, or concatenate it first?
I’m sorry if this sounds a little bit stupid, I am just a beginner.
Thanks for your help

If you have all the date occurrences in Sheet1, column A. You could have a list of hours in column A of a second sheet (01-Jan-2015 05.00, 01-Jan-2015 06.00, 01-Jan-2015 07.00 etc.). In column B in that sheet you place a COUNTIFS formula which counts all date occurrences between the date and hour in column A and column A + 1 hour:
=COUNTIFS(Sheet1!A:A,">=" & A1,Sheet1!A:A,"<" & A1+(1/24))
See COUNTIFS function for reference.

SUMPRODUCT difference between two dates for THIS WEEK entries only

I have a column D containing all the Dates in DD/MM/YYYY format, and I would like to show the count of missed days for THIS WEEK values only from all the entries in column D.
In other words, if there is a difference between two Dates in column D and it occured this week, I would like to count it.
I have below formula to calculate "Total days missed" between first and the last entry in Dates column D, however I can't adopt this formula to display "Days Missed" for THIS WEEK only entries.
=SUMPRODUCT(--ISNA(MATCH(ROW(INDIRECT(MIN($D$18:$D$500)&":"&MAX($D$18:$D$500)));$D$18:$D$500;0)))
Sample of data set.
Please help, thanks.
For O365, in accord with your statement that there can be multiple entries of one date, I suggest the following (assuming your dates are real dates and not text strings that happen to look like dates):
Total Missing Dates
=MAX($D$18:$D$500)- MIN($D$18:$D$500)+1-COUNT(UNIQUE($D$18:$D$500))
Missing Dates THIS WEEK obviously, you'll need to define the first and last dates of THIS WEEK
=7-COUNT(FILTER(UNIQUE($D$18:$D$500),(UNIQUE($D$18:$D$500)>=wkStart)*(UNIQUE($D$18:$D$500)<=wkEnd)))
If your week starts on Monday, you can calculate:
wkStart: =TODAY()+1-WEEKDAY(TODAY()-1)
wkEnd: =wkStart+6
More generally, to return a particular day of the week prior to someDate (or wkStart):
wkStart = someDate - WEEKDAY(someDate - DayOfWeek)
where DayOfWeek is: Sunday=1 Monday=2 , etc
So, making someDate = TODAY()+1 ensures that if today is monday, it will return today and not the monday from a week ago.
HINT: It might be more convenient to define wkStart and wkEnd as a Named formula.

How to collect number of days from a month in excel

I have a column which will have some days from a month in dd-mm-yyyy format. What I need to get total number of days from each month mentioned in that column. The column might not contain all days from each month.
Example :
Column A :
2017-01-01
2017-01-02
2017-01-17
2017-01-27
2017-02-08
In above example, from 2017 Jan, I have 4 days and from Feb I have one day. I need this count for a IF statement to run in C column. ie, in C1 there will be an IF function which will check the month in A1 and count the total number of days for that specific month from A column. If that count is below a specific digit, I need to perform a formula otherwise a different one. This will repeat for all C cell
If this column contains all date from each month I can use Day function to get total days, but here how Can I collect it
This will work: =SUMPRODUCT(1*(MONTH($A1:$A5)=D1))
And an example of manipulating basing on the result:
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=D1))<3;"good";"bad")
Another one when row number represents a month (JAN in C1, FEB in C2...):
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=ROW()))<3;"good";"bad")
In your case:
=IF(SUMPRODUCT(1*(MONTH($A1:$A5)=ROW()))<10;function1();function2())
Array formula - use Ctrl+Shift+Enter:
=SUM((MONTH($A$1:$A$5)=MONTH(A1))*(YEAR($A$1:$A$5)=YEAR(A1)))

Excel - how to get if a date is a specific day of the week?

I have a spreadsheet that tracks average file processing times over the course of a month. One of the macros and stats that we like to pull, is performance on Mondays (as the files are a little built up over the weekend). The spreadsheet is organized into columns by weekdays of the month:
The dates are formatted MM/DD/YYYY, so I would think Excel has a date function that it can determine weekday based on that date value.
Currently, I just have to manually tell the Macro which columns are Mondays, like so:
=AVERAGE(B20,G20,L20,Q20)
So, instead of manually, how would I get the average over the range of say, B20 to V20, only if the day of the week is Monday (the date cells are in row 1, so B1 to V1)?
To determine the weekday of a date in EXCEL use the =WEEKDAY() formula, which evaluates as 1 (Sunday) to 7 (Saturday)
e.g. If A1 contains 12/31/2016 (or 31/12/2016 if you're from where I'm from), the formual =WEEKDAY(A1) would evaluate to 7 (indicating that the last day of 2016 was a Saturday)
To apply this formula to your problem: (assuming that the dates are in row 1 and the values are in row 2)
insert a new row to hold the WEEKDAY() value (say, row 2)
in cell A2 type in =WEEKDAY(A1)
copy this formula as far right as necessary (to include all your dates)
Your average for Mondays is calculated as =AVERAGEIF(2:2, 2, 3:3)
Possibly, you can add a column called [Day Of The Week] and use the following formula to display the day.
TEXT(B4,"dddd")
Then add an 'If'statement to your result cell.
simply
=SUMPRODUCT((MOD(B1:V1,7)=2)*B20:V20)/SUMPRODUCT((MOD(B1:V1,7)=2)*1)
should give the average of all values from B20 to V20 if the corresponding cell in row 1 is a monday.
the first part sums the values of all mondays and the second part counts them (sum / count = average) ;)
If you have any questions, just ask.
If your date is in A1, you can use =Text(A1,"dddd") to determine the day of the week (it will return the name, "Monday", "Tuesday", etc.) so then you could do perhaps:
=If(text(A1,"dddd")="Monday",[do whatever],[do whatever]) (may need a helper row/column to hold the text of the weekday)
(Or use AverageIf() and use the Text() idea.)

SumIf by Weekday & User

I have a table that I am trying to perform a sumif on, but the catch is I need the formula to filter the data by two range criteria first.
Column A = Date, Column D = User, Column H = time to be summed
Basically, I want to be able to sum the time values by user, but then I also need to be able to split this time between weekdays and weekends.
Thus, if user A has 1 session of 0:30 on Monday, Wednesday, Saturday and Sunday, then I want the formula to be capable of summing the 2 hrs such that I can have 1 column in a separate table with the weekday hours, and the column next to this with the summ of all weekend hours.
Any ideas you might have on how I can solve this with a formula rather than redesigning the tables (as they're not mine to redesign) would be most appreciated.
You need to move to a SUMPRODUCT function in order that you can introduce the WEEKDAY function to be used in the criteria.
    
The formula in K2:L2 are,
=SUMPRODUCT(($D$2:$D$99=$J2)*(WEEKDAY($A$2:$A$99, 2)<6), $H$2:$H$99)
=SUMPRODUCT(($D$2:$D$99=$J2)*(WEEKDAY($A$2:$A$99, 2)>=6), $H$2:$H$99)
Fill down as necessary.

Find last digits with IF

I have lots of cells in the spreadsheet that contains the whole year, date and stock prices, but I only need the dates from 25th of the last month till the 5th of this month.How can I write a function to do that? For example if the cells are like this in the column:
19900101
19900102
19900103
19900104
19900105
.
.
19900125
19900126
19900127
19900128
19900129
19900130
19900131
I want it to show only days (1,2,3,4,5,25,26,27,28,29,30,31) with the date format.
The date shows in the text format and I've tried format cell to change it but it doesn't work.
For a slightly different approach, assuming you want to return the A2 value only if it represents a date in the last 5 or first 5 days of any month you can use this formula in B2
=IF(DAY(TEXT(A2,"0000-00-00")+5)<11,A2,"")
TEXT function converts your data to a real date then if you add 5 days to that date then any date that was originally in the last 5 or first 5 of the month will now be in the first 10 days of the month.....so it's sufficient to check that the day is < 11. That will pick up 27th to 31st of a 31 day month, 26th to 30th of a 30 day month etc.
you could use a formula and then filter by rows with data...
As an example (given it's difficult to discern if you always want the first 5 and last 5 of a month or what....)
=IF(RIGHT(A2,2)*1<=2,A2,IF(RIGHT(A2,2)*1>=29,A2,""))
Based on all the edits and comments, these should be the function you need.
=IF(OR(A7-A2>5,MOD(A2,100)<=5),DATE(LEFT(A2,4),MID(A2,5,2),RIGHT(A2,2)),"")
You should place it in cell B2 and then do all the desired filtering, as explained in xQbert's answer.
