How to calculate a lunch break
Subtract the break start from the break end. A break from 12:00 PM to 12:30 PM lasts 30 minutes, which is 0.50 decimal hours.
Break duration = break end − break start
Breaks that cross midnight
When the end is earlier than the start, ClockSlate assumes the break ended on the following day. Check the entries carefully if a very long duration appears.
Frequently asked questions
Is a 30-minute lunch 0.30 hours?
No. Thirty minutes is half of 60 minutes, so it equals 0.50 decimal hours.
Does this decide whether my break should be paid?
No. The calculator only measures time. Break requirements and paid status depend on the applicable policy and law.
