Calculate minutes

[braydon16]

Can you tell me how to subtract minutes on an Excel
spreadsheet?
We have just completed a time study of clinical flow and I wanted to set
up the results on a spreadsheet that will automatically calculate
minutes
spent on each function. I know how to subtract minutes IF we were to
round the minutes to nearest 15 minutes and use fractions rather than
time, which is how we do it in payroll. However, I want exact minutes
for this study.

How are the cells formatted where your initial entries are? You need to enter them as hr:min or hr:min:sec. You can format your difference as [mm] or [mm]:ss. See attached. Does this help?
