Frequently asked questions
Which time calculator should I use?
Use the Time Calculator for durations and adding/subtracting time. Use the Hours Calculator for multi-day work hours with weekly totals.
Do you handle overnight shifts?
Yes — when end is earlier than start without dates, we assume the next day, and breaks are subtracted.
What is the difference between the Hours Calculator and Time Calculator?
The Hours Calculator is tailored for daily work timesheets and payroll clock-ins with unpaid breaks, while the Time Calculator adds, subtracts, and converts arbitrary time intervals.
How do I convert timesheet minutes into decimal payroll hours?
Divide elapsed minutes by 60. For example, 8 hours and 45 minutes equals 8 + (45/60) = 8.75 decimal hours.
