excel: comparison between hours - excel

I have this worksheet to compare two hours with a condition and shows me a result.
If the value inserted in cell is less than the sum of two other hours, the conditional should warn me that I need to insert a bigger value.
I had wrote the formula below:
=IF(X4>(U4+$T$7);"The value is ok";"Insert a bigger value")
The following image represents cells affected on my worksheet:
Cells affected by formula.
As you may see my Excel is in Portuguese therefore the "SE" function is the same as "IF".
The X7 cell with "7:00:00" only represents the sum that I want to compare just to check if the result was correct.
Anyway, as you can see in this image the result is "Insert a bigger value" when actually, 17:00 (5 PM) is bigger than 7:00 (AM). Is there any way to solve this mistaken result?
All my cells are formated from "General" to "Hour".


use the hour function like this
if(hour(X4)

How to filter out partial match in an Excel row?

I have an Excel sheet with dates in the rows. A given month should be used only once in a row. How can I filter out, if there are two dates in the same row from the same month?
For example I have the following array, and I would like to have as a result, that there is a match in this row (2012-03).
2012-03-04 2012-02-05 2012-04-06 2012-03-07 2012-10-08 2012-11-09 2012-12-10
I have tried to combine aggregate and match functions, but I cannot find out how to do it properly.
One of my codes, of course it gave an error:
=aggregate(9,6,(MATCH("*"&LEFT(A8,7)&"*","*"&LEFT(b8,7)&"*",0), MATCH("*"&LEFT(b8,7)&"*","*"&LEFT(c8,7)&"*",0)))
Ok, now I have tried another way, and I could get a solution, but with a code which is like a km long...I have first created a new dataset, cutting down the days by using: =""&LEFT(A8,7)&""
Then I have compared all the cells in a given row of my new dataset. Could someone help me how to shorten the exact( ) parts? The aim is to compare all.
=if((or(exact(A2, B2), exact(A2,C2),exact(A2,D2),exact(A2,E2),exact(A2,F2),exact(A2,G2),exact(A2,H2),exact(A2,I2),exact(A2,J2),exact(A2,K2),exact(A2,L2),exact(A2,M2),exact(A2,N2),exact(A2,O2),exact(A2,P2),exact(A2,Q2),exact(A2,R2),exact(B2,C2),exact(B2,D2),exact(B2,E2),exact(B2,F2),exact(B2,G2),exact(B2,H2),exact(B2,I2),exact(B2,J2),exact(B2,K2),exact(B2,L2),exact(B2,M2),exact(B2,N2),exact(B2,O2),exact(B2,P2),exact(B2,Q2),exact(B2,R2),exact(C2,D2),exact(C2,E2),exact(C2,F2),exact(C2,G2),exact(C2,H2),exact(C2,I2),exact(C2,J2),exact(C2,K2),exact(C2,K2),exact(C2,L2),exact(C2,M2),exact(C2,N2),exact(C2,O2),exact(C2,P2),exact(C2,Q2),exact(C2,R2),exact(D2,E2),exact(D2,F2),exact(D2,G2),exact(D2,H2),exact(D2,I2),exact(D2,J2),exact(D2,K2),exact(D2,L2),exact(D2,M2),exact(D2,N2),exact(D2,O2),exact(D2,P2),exact(D2,Q2),exact(D2,R2),exact(E2,F2),exact(E2,G2),exact(E2,H2),exact(E2,I2),exact(E2,J2),exact(E2,K2),exact(E2,L2),exact(E2,M2),exact(E2,N2),exact(E2,O2),exact(E2,P2),exact(E2,Q2),exact(E2,R2),exact(F2,G2),exact(F2,H2),exact(F2,I2),exact(F2,J2),exact(F2,K2),exact(F2,L2),exact(F2,M2),exact(F2,N2),exact(F2,O2),exact(F2,P2),exact(F2,Q2),exact(F2,R2),exact(G2,H2),exact(G2,I2),exact(G2,J2),exact(G2,K2),exact(G2,L2),exact(G2,M2),exact(G2,N2),exact(G2,O2),exact(G2,P2),exact(G2,Q2),exact(G2,R2),exact(H2,I2),exact(H2,J2),exact(H2,K2),exact(H2,L2),exact(H2,M2),exact(H2,N2),exact(H2,O2),exact(H2,P2),exact(H2,Q2),exact(H2,R2),exact(I2,J2),exact(I2,K2),exact(I2,L2),exact(I2,M2),exact(I2,N2),exact(I2,O2),exact(I2,P2),exact(I2,Q2),exact(I2,R2),exact(J2,K2),exact(J2,L2),exact(J2,M2),exact(J2,N2),exact(J2,O2),exact(J2,P2),exact(J2,Q2),exact(J2,R2),exact(K2,L2),exact(K2,M2),exact(K2,N2),exact(K2,O2),exact(K2,P2),exact(K2,Q2),exact(K2,R2),exact(L2,M2),exact(L2,N2),exact(L2,O2),exact(L2,P2),exact(L2,Q2),exact(L2,R2),exact(M2,N2),exact(M2,O2),exact(M2,P2),exact(M2,Q2),exact(M2,R2),exact(N2,O2),exact(N2,P2),exact(N2,Q2),exact(N2,R2),exact(O2,P2),exact(O2,Q2),exact(O2,R2),exact(P2,Q2),exact(P2,R2),exact(Q2,R2))),"same month","ok")
Thank you in advance.

I am not sure if there is a better way, but this is how I'd tackle the problem based on my Excel knowledge:
Add data of dates above in cells A1-G1
On row below date add formulas for dates: A2=DATE(A1) ..... G2=DATE(G1)
At the end of the original row of dates add the numbers 1 thru 12:
using formula cell H1=1, I1=H1+1 ..... S1=R1+1
After the months on row 2:H2=COUNTIF($A2:$G2,H1) ..... S2=COUNTIF($A2:$G2,S1)Counting frequency for each of the 12 months
T2=MAX(H2:S2)
Then select on cell T2being more than 1.
Here it is as a Google sheet (you can download it and open in Excel if you want)

Maybe this will help. Assume that the range of dates is in $A$1:$G$1. Also assume that the entries are numerical dates; if they are instead text you can handle this by using the DATEVALUE function. Then we can get the years and months of the range with:
{=YEAR($A$1:$G$1)}
{=MONTH($A$1:$G$1))
This and all other formulas must be entered as array formulas (CrtlShiftEnter).
We next convert back to a date, but use 1 for the day, so that all dates get shifted to the first day of the month (this means that any dates from the same month are shifted to the same date):
{=DATE(YEARS,MONTHS,1)}
We can produce an NxN comparison of the shifted dates by:
{=TRANSPOSE(SHIFTED_DATES)=SHIFTED_DATES}
We can count the number of True's in this array by:
{=SUM(--(ARRAY))}
If there we no dates from the same month we'd expect this to sum to N because this method compare each date to itself as well as the other dates. The causes the N elements on the main diagonal of this array to be True. If any dates are in the same month off-diagonal elements will also be True. So to detect if there are dates from the same month we make the comparison:
{=SUM(--(ARRAY)) > N}
or more generally:
{=SUM(--(ARRAY)) > COUNT($A$1:$G$1)}
Rolling all of these up into one formula:
=IF(SUM(--(TRANSPOSE(DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1))=DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1)))>COUNT(DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1)),"same month","ok")
If your dates are in a range other than $A$1:$G$1 then make the appropriate substitutions.
Hope that helps.

Excel Formula to Calculate Text within a date range

I am trying to calculate values within a specific date range. The data I want to split between each month and the values: Successful, Incomplete and Failed.
I've tried pivot tables with this data but it doesn't work for me, also lacking pivot table excel experience. Formulas I'm more comfortable with.
I am using the following statement to at least get the total number of a value I add into it;
=COUNTIF('Jan 19'!$C$2:$C$1159,"Value")
Ex. If I put into the value "Successful" I get the total number of successful records.
I am looking into having a formula that I can input a specific month/date range (Jan, Feb, etc) and a value to get a count.
Ex. =Formula ((RangeOfData, "Value") AND (RangeOfData, (FromDate, ToDate))
I expect to the get the total number of a value(s) within a specific date range. If there isn't any data then the results would be blank or 0.

I'd use the formula COUNTIFS() as #cybernetic.nomad pointed in the comments so you can put more conditions on the COUNT:
=+COUNTIFS('Jan 19'!$B$2:$B$1159,">="&F3,'Jan 19'!$B$2:$B$1159,"<"&G3,'Jan 19'!$C$2:$C$1159,H3)
In the formula above I guessed the dates are in the COLUMN B, if not, you need to change it in the formula above.
To do that we should put the range we want to look at in a couple of cells where you would put the date range, in the example above:
F3 is the start date (if you want February of this year should be 1/2/2019).
G3 is the final date (if you want February of this year should be 1/3/2019).
H3 is where you can write "value", "successful" or any other string you are trying to count.

Excel - automatically generate list of dates, given multiple date ranges in one column

I better show you. This is how my list looks like:
And this is how I want it to be:
Basically, in the first picture I have different date ranges, for each date range I have a those two metrics, Sessions and Users and the final result should be a sort of explosion of all date ranges into single dates, considering that certain dates can be included in more than 1 date ranges (e.g. date 2017-08-12) is included in both first and second row.
And last but no least, the end date shouldn´t be counted.
Can someone help me out?
Thanks a million

This is the outline of a solution:
Split each from/to date in your input table into its 2 constituent dates. You will need to use the string functions (LEFT, RIGHT and MID) to extract the numbers for the year, month and day values. These will still be strings of characters, so use the VALUE function to convert them to actual numbers and then use the DATE function to assemble them into a proper date value in Excel. (You may need to format your results using a date format, as Excel stores its dates as number of days since 01/01/1900, so 11/08/2017 is held in Excel as 42958.) Add as many helper columns as you need to your input table to achieve this.
Subtract 1 from each end date, this corrects the dates ranges so that the end date is included.
The first start date and the last end date define the range of output dates. So start your output table with the first date and in the cell below use a formula to add 1 to this date and copy the formula downwards until you get to your last possible output date.
To get the results for each possible output date, you need to find
which date ranges it belongs to. It belongs to a date range if it is
greater than or equal to the range's start date and less than or
equal to the end date. However, rather than comparing each output
date with individual start and end dates it is possible to compare
each output date with all the start and all the end dates at once. An expression such as A10>=E2:E7 generates an array of 6 elements with values
TRUE and FALSE according to whether A10 is greater than or equal to
E2, E3, E4, E5, E6 and E7 respectively. So, you can use this approach to generate an array of TRUE/FALSEvalues showing whether a particular output date is greater than or equal to (ie on or after) each range's start date. Similarly, you can get an array showing whether the same output date is less than or equal to (ie on or before) each range's end date.
The versatile SUMPRODUCT function can now be used to combine the arrays and the relevant sessions/users values from the input table to get the relevant values for the output date. For example, if the start dates are in E2:E7, the end dates in F2:F7, the sessions in B2:B7 and the output date in A10 then a sutable formula for determining the number of sessions to attribute to the output date would be =SUMPRODUCT(($A10>=$E$2:$E$7)*($A10<=$F$2:$F$7)*(B$2:B$7)). This formula could be copied to give results for all output dates and, assuming the input data for users is in C2:C7, it will also give the results for users if copied into the column adjacent to the sessions results. In this formula, the TRUE and FALSE values are effectively converted to 1 and 0, respectively.
A few points: (i) if you don't know how dates work in Excel then find out, it makes tasks such calculating the number of days between two dates or the date n days before/after a particular date extremely easy using simple arithmetic; (ii) don't confuse strings of text which look like dates with dates that can be manipulated arithmetically in Excel; (iii) I believe there are some errors in your example - 16/08/2017 is a date in two of your input ranges and should have results of (2,2) not (1,1) and 17/08/2017 is similarly in error.
I have used this approach in the illustration below and, to test its robustness, I have added an extra row of input data which has sessions different from users and which yields one date (19/08/2017) which does not match to any input range.
The output date range was generated as follows:
Cell A10: use formula =E2
Cell A11: use formula =1+A2
Cells A12, A13, ... copy formula in cell A11

Median on weekdays

I'm trying to determine the median of a set of data for each weekday. Currently, the data is in two columns, date and value. Some of the value rows are blank, as the data to be analyzed hasn't be entered yet. I've had a look at the median-if array formula, but when I combine it with Weekday function I just get an error
{=Median(if(Weekday('Data'!A:A)=1, 'Data'!B:B)}
This is the current formula I'm working with to calculate the median value for Sundays, and all I get out of it #VALUE!.

Copying a Comment from #sous2817:
Rather than use a whole column reference, you should just use the range you want to evaluate for the calculation. If you have something other than a date in Column A, it will throw the #Value error.

Finding the value in excel or vba

Column A Column B
13-06-2013 10:50
13-06-2013 11:30
13-06-2013 12:40
14-06-2013 10:30
I need to find the values which are before a particular entry date and time.
For example, say I want to find the values in the example table above that are immediately prior to the values "13-06-2013" and "12:30".
Since 12:30 is not in column B, how do I find the values I am looking for? The answer should be 13-06-2013 and 11:30.

C7 =VLOOKUP(A7&B7,A1:C4,3,TRUE)
Here A1 = B1&C1
A B C
1 414380.451388888888889 13-06-2013 10:50
2 414380.479166666666667 13-06-2013 11:30
3 414380.527777777777778 13-06-2013 12:40
4 414390.4375 14-06-2013 10:30

6 Enter date Enter Time Returned Time
7 13-06-2013 12:30 11:30:00
Setting 'range_lookup' as 'True' adds the flexibility to return the closest approximate value if the exact value is not available.

I think you're looking for something like this. using index and match.
I didn't take into account the date for now. but this gives you an example.

You can compare date strings with operators like > or < etc. Concatenate your values in columns A & B, compare to the desired date/time string. In cell C1 put the following formula, and then drag down:
="13-06-2013 12:30"<A1&" "&B1
or more specifically, depending on which "12:30" you want (AM or PM), ="13-06-2013 12:30AM" or ="13-06-2013 12:30PM"
Your data in column B may default to AM unless otherwise specified/imported differently, so you may need to tweak the data or to account for this.

Here is another approach to answering your question that uses a combination of MATCH, INDEX, and array operations to provide a compact formula solution that does not rely on helper columns.
I'll assume that your two columns of dates and times are in cells A2:B5, and the two date and time values that you want to look up are in cells A9:A10. Then the following two formulas will return what you require, the latest date and time values in your data that are less than or equal to the date and time that you are looking up. (The dollar signs in the formulas are hard on the eyes, but they are important if you will need to copy the formulas to other locations; for clarity, I omit them in the discussion that follows.)
DATE: =INDEX($A$2:$B$5,MATCH(A9+A10,$A$2:$A$5+$B$2:$B$5,1),1) --> 13-06-2013
TIME: =INDEX($A$2:$B$5,MATCH(A9+A10,$A$2:$A$5+$B$2:$B$5,1),2) --> 11:30 AM
These are array formulas and need to be entered with the Control-Shift-Enter key combination. (Of course, only the bits starting with the equal (=) sign and ending with the last parenthesis need to be entered into the worksheet.)
Things to consider:
The formulas assume that your data are valid Excel date and time values. Excel date values are whole numbers that count the number of days that have elapsed since January 1, 1900; Excel time values are decimal amounts between 0 and 1 that represent the fraction of 24 hours that a particular time represents. While your example data don't display AM or PM, I assume that their underlying values do have that information.
If your values are text (having been imported from another source, for instance), you should convert them to date/time values, if lucky, using only Excel's DATEVALUE and TIMEVALUE functions; if not so lucky, using some combination of Excel's string manipulation functions as well. (The values could be kept as strings, but you would almost certainly need to massage them so they would compare correctly "alphabetically" - much easier just to deal with Excel date/time values.)
If they are not already, your dates and times will need to be sorted from smallest to largest. (Your sample looks like they are sorted, and the formulas assume as much.)
How the formulas work
The basic idea behind the formulas is two-fold: first find the row in your data that holds the latest (largest) date and time that is still less than or equal to the date and time you are looking up. That row information can then be used to fetch the final result from each column of the data range (one for date and one for time).
Since both date and time figure in to what point in time is latest, the date and time components of both the value to be looked up and the values that will be searched must be combined somehow.
This can be achieved by simply adding the dates and times together. This does nothing more than what Excel does: an Excel date/time value has an integer part (the number of days since 1/1/1900) and a decimal part (the fraction of 24 hours that a particular time represents).
What is neat here is that the adding up of the dates and times - and the lookup of the particular date and time - can be done all at once, on the fly.
Take a look at the MATCH: The cells that contain the date and time to be looked up - A9 and A10 - are added together, and then this sum is matched against the sum of the date column (A2:A5) and the time column (B2:B5) - an operation that is possible of Excel's array arithmetic capabilities. The match returns a value of 2, indicating correctly that the date and time that fill your requirements are in row 2 of the data table.
DATE/TIME MATCH: = MATCH( A9+A10, A2:A5 + B2:B5, 1 ) --> 2
The 1 that is the final argument to the MATCH function is an instruction that the match results be calculated to be less than or equal to the value to be looked. It is the default value and is often omitted, or replaced with another value (for example, using a value of 0 will produce an exact match, if there is one).
(For readability, I've removed the dollar signs that are in the full formula; these anchor a range so that it remains the same even if the formula is copied to another location.)
Having figured out the row to look in, the rest of the formula is straightforward. The INDEX function returns the value in a data range that is at the intersection of a specified row and column. So, for the date in question, the formula reduces to:
DATE FETCH: = INDEX( A2:B5, 2, 1) --> 13-06-2013
In other words, INDEX is to return the value in the second row and first column of the data range A2:B5.
The formula for the time proceeds in exactly the same fashion, with the only difference that the value is returned from the second column of the data range.
