Ever struggle to calculate & add hours in Google Sheets? I'm going to show you how to create formulas to add up each row or to calculate the total for a column, even when the out or end time is the next day (solving that pesky negative hours situation!).
Simple Formula: =(endTime-startTime)*24
Compensate for next day times: =((endTime+1)-startTime)*24
You can make a copy of the final Google Sheet showing both the normal hour calculations and the next day calculations here: bit.ly/3FBfAjn
You can learn a lot more about how time works in Google Sheets in this video: youtu.be/2wJGTORVX4U
