The formula
How this calculator works
Lunch return time = lunch start + break length
The planned return mode adds the allowed break duration to your start time. The actual-duration mode measures the time between clocking out and back in.

Good to know
Edge cases and common mistakes
- A return time after midnight is automatically carried into the next day.
- The actual-duration mode limits breaks to four hours to catch accidental time entries.
- Only an unpaid lunch normally extends the clock-out calculation.
- Browser reminders are most reliable while the tab or installed app remains open.
Answers
Frequently asked questions
If lunch starts at 12:15, when do I return after 30 minutes?
Return at 12:45 PM.
What time do I return from a 45-minute lunch?
Add 45 minutes to the time your lunch started. For example, a 12:00 PM lunch ends at 12:45 PM, while a 12:30 PM lunch ends at 1:15 PM.
What time do I return from a 60-minute lunch?
Add one hour to your lunch start time. If lunch begins at 1:00 PM, return at 2:00 PM.
Can I calculate how long my lunch actually lasted?

Does a paid lunch change my clock-out time?
A paid lunch is already part of paid work time and normally is not added again. An unpaid lunch extends the workday.
