About this calculator
A time card turns clock-in and clock-out stamps into hours you can pay, bill, or compare against a contract. Enter your start time, end time, unpaid break, and how many days you repeat that shift each week. You get daily hours, a weekly total, and optional overtime split when a day runs past eight hours.
This fits freelancers logging client hours, shop staff on rotating shifts, remote workers tracking billable time, and anyone checking whether a job offer's '45-hour week' matches reality after breaks. Times work as 24-hour HH:MM (09:00, 18:30) or decimal hours (9.5 for nine and a half). Night shifts that cross midnight add 24 hours automatically when clock-out is earlier than clock-in.
The eight-hour overtime line is a common full-time standard — toggle it off if your employer uses a different threshold. Pair this with the [[hours]] calculator for quick same-day math, the [[workdays]] calculator for business-day counts, and the [[time]] calculator for adding or subtracting durations.
Common uses
- Payroll prep — weekly hours from daily clock-in/out records
- Freelance billing — billable hours minus lunch breaks
- Shift planning — see weekly load before accepting extra days
- Contract checks — compare offered hours against actual shift pattern
- Part-time schedules — scale a short daily shift across fewer days
Frequently asked questions
Can I enter times as decimal hours instead of HH:MM?
Yes. Type 9.5 for nine hours thirty minutes, or 17.75 for 5:45 PM. HH:MM format (09:00, 17:30) works too. Both feed the same calculation.
What if my shift crosses midnight?
When clock-out is earlier than clock-in (e.g. in at 22:00, out at 06:00), the calculator adds 24 hours to the end time. Break minutes still subtract from the total span.
How is overtime calculated?
When overtime tracking is on, any daily hours above 8 count as overtime. That excess is multiplied by days per week for a weekly overtime total. Regular hours are capped at 8 per day times days worked.
Should I include paid breaks in the break field?
Only enter unpaid break minutes — lunch or rest time that does not count toward worked hours. Paid breaks stay out of the break field so they remain in your daily total.
How do weekly hours relate to a 40-hour work week?
Five days at 8 hours each gives 40 weekly hours. Change days per week for part-time patterns (3 days × 8 h = 24 h) or six-day schedules common in some industries.
