Excel/Subtracting house from date


Hi Tom,

I have a list of times in the following format: 06/24/2014  1:31:21 PM.  How do I subtract 4 hours from the time so that the output reads: 06/24/2014  9:31:21 AM.




do you mean so that the output appears in another cell?

if so then assume the cell with the first date/time is A1 and in B1 you would put the formula


that worked for me.   (make sure the cell with the formula is formatted the same as the original cell.

If you want to change the cell in place - in other words, change A1 to display 06/24/2014  9:31:21 AM

in a blank cell put in the formula
Copy that cell,

Select A1 (still assuming the original value is in A1) and do a Paste Special and choose Values and subtract.

Again, that also worked for me.
