I'm working on some VBA to take some of the drudgery out of payroll.
Public Function ThisFriday() As Date
ThisFriday = Date + 8 - Weekday(Date, vbFriday)
End Function
Public Function LastFriday() As Date
LastFriday = Date + 1 - Weekday(Date, vbFriday)
End Function

James shares his formula for determining which week of the month a particular date is in. He has a list of Sundays, each of which is the first day of the week. His formula:
ROUNDUP(((DAY(A1)-1)/7)+1,0)
James' formula only works if A1 contains the first day of the week. If you want to calculate the [...]
Bob has a workbook with several web queries in it. In each of the web queries, the first column is a "date". He needs to find the minimum and maximum date for all web queries.

VBA from Excel to Desktop
In the Workbook_Open event, I have

I was talking with a workmate of mine and he mentioned that he is a swimming coach.
He told me that it's difficult to record swimming times in Excel.
His approach was to record Minutes, Seconds and Splits (Split Seconds) as separate columns. Now, I can only imagine what sort of frustrating (if not impressive!) formulas this [...]
DATEDIF is a worksheet function that will return the difference between two dates in a variety of intervals. As far as I can tell, DATEDIF truncates any partial intervals. If the difference was two months and one day, it would return two months. I had a situation where I needed to count [...]
