How to use this clock in calculator
Enter every clock-in and clock-out pair for the selected date. Use Now when you want the current local time, and Add another punch for another period. Check the daily hours and decimal result. An unfinished period is flagged rather than counted. Select another date to keep additional daily records in this browser.
Clock-in and clock-out pairs, not one long shift
A day can contain several working periods. If you leave at lunch and clock back in afterward, enter those two pairs separately rather than treating the first arrival and final departure as uninterrupted work. This clock in clock out calculator starts with three empty rows so individual punches are easy to add. Only completed pairs contribute to the total. The gap between them is not counted, so no extra deduction is needed for that same gap. This single-day layout suits someone checking today’s punches; the time card calculator offers a two-week record instead. Blank rows stay ignored. A missing clock-out remains open and displays a clear message until you enter the actual time.
What counts as hours worked
The span from the first clock-in to the last clock-out can include unpaid gaps. This tool adds the periods you record and subtracts only the unpaid breaks entered within those periods. It performs arithmetic, not a legal determination of compensable work. Waiting time, on-call duties, exemptions and overtime can depend on the circumstances and applicable rules. Review disputed records with your employer or payroll contact before using the total. Time is calculated from wall-clock entries; a daylight-saving clock change requires a separate adjustment.
Lunch and short breaks
Use the break field for unpaid time inside a pair, or mark it Paid to retain it. This page defaults breaks to zero because separate punches commonly already exclude lunch. Never deduct the same gap twice. Under federal guidance, employer-provided short rest breaks are generally paid; verify the rule for your circumstances. A 30-minute break equals 0.5 hours, not 0.3. Set the minutes directly rather than entering decimal fractions in the break field.
Forgot to clock in or clock out?
Ask your supervisor or HR how to correct the original record. Check your schedule and other reliable records to establish the actual time worked. Compare the day with your usual pattern only as a starting point to verify, not as proof of the missing punch. Ask payroll how any company rounding policy applies after the actual time has been established; rounding cannot recover an unknown time. Do not invent an entry simply to fill the field. Keep the period incomplete here until confirmed. Employers covered by the FLSA have recordkeeping duties; this local calculator does not replace the official record or submit a correction for you.
Overnight and split shifts
A pair such as 22:15–06:05 ends the next day and totals seven hours fifty minutes before unpaid breaks. You do not need to enter a negative duration or change the end to 30:05. For split shifts, add a separate pair for each period. Assign overnight work to its start date for this local record; split a period manually when a reporting boundary requires separate dates.
Rounding rules and payroll decimals
Leave rounding off for exact minutes, or choose the nearest 5, 10, 15, 30 or 60 minutes in Calculation settings. Rounding applies once to each daily total after unpaid breaks, or once to the overall total. Confirm which method your payroll process uses before enabling it. Convert minutes to decimal hours by dividing by 60: 15 is 0.25, 30 is 0.5 and 45 is 0.75. This punch in calculator displays two decimal places.
| Minutes | Decimal hours |
|---|---|
| 15 | 0.25 |
| 20 | 0.33 |
| 30 | 0.50 |
| 45 | 0.75 |

Frequently asked questions
How do I calculate hours worked from clock-in and clock-out times?
For each completed pair, subtract clock-in from clock-out, then subtract any unpaid break inside that period. Add the resulting periods. If the clock-out time is earlier, it is treated as the next day. Gaps between separate pairs are already excluded, so do not deduct the same lunch again.
Can I enter more than one clock-in in a day?
Yes. This page begins with three empty periods and lets you add more using Add another punch. Enter a matching clock-out for each clock-in and adjust breaks for each period. The calculator adds completed pairs automatically. Unfinished periods stay excluded until their missing times are supplied and valid.
I forgot to clock out — how do I calculate my hours?
Ask your supervisor or HR about correcting the record. Check your schedule and other reliable evidence, verify any estimate from your usual pattern, and ask payroll about rounding only after establishing the actual time. Keep the period incomplete until confirmed. This calculator cannot determine a missing punch or amend an employer’s official records.
Does it handle overnight shifts?
Yes. An end time earlier than its start is treated as the following day. For example, 22:15 to 06:05 gives seven hours fifty minutes with zero unpaid break. The period is assigned to its start date. Daylight-saving changes and workweek boundaries may require a manual split or separate adjustment.
Are breaks deducted automatically?
Only the unpaid minutes you enter inside a completed period are deducted. This page starts with zero break minutes because separate punch pairs often already exclude lunch. Mark Paid to retain entered break time. Check each period and do not subtract a lunch gap again when it already lies between two pairs.
Is this a time clock app?
This is a browser calculator for manually entered times. Now inserts the current local time into a field, but does not submit an official attendance punch. Entries stay on this device and are not uploaded. For employee check-ins, shared attendance records or manager approvals, use an attendance system appropriate to your workplace.
