Common questions
Should I use the time card or the timesheet calculator?
Use the time card calculator for one week with any number of shifts per day and a break deduction. Use the timesheet calculator for one or two dated weeks with lunch-out and lunch-in punches and CSV export.
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60 and add them to the hours: 8 hours 45 minutes is 8 + 45 ÷ 60 = 8.75 hours.
Do these calculators handle shifts past midnight?
Yes. When the end time is earlier than the start time, the shift is treated as ending the next day.
