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.
