Estimate when an 8-hour day really ends
Adding break time makes the end-of-day estimate more realistic than counting paid hours alone.

How it works
What the calculator is doing
Enter the start time, total paid work hours, and unpaid break minutes.
The calculator adds paid work time and break time to the start time.
It shows the estimated end time plus the total on-the-clock duration used in the calculation.
Understanding your result
This estimate works well for planning a day, but it is not a payroll record. Employer policies around rounding, break rules, and workday definitions may still change the official end-of-day calculation.

FAQ
Common questions
How does this calculator estimate end time?
It adds the total paid work hours and unpaid break time to the start time you enter.
Why show total on-the-clock time too?
Because it helps explain why the end time is later than the paid hours alone when an unpaid break is included.
Can the estimate roll into the next day?
Yes. If the total time runs past midnight, the calculator notes that the end time crosses into the next day.
