Hours Calculator: Time Between Two Times and Time Card
This hours calculator counts the hours and minutes between two times, subtracts unpaid breaks and handles shifts that run past midnight. Below it, a weekly time card adds up every day’s hours in both hours-and-minutes and decimal form, and works out your pay from an hourly rate.

Quick answer: To calculate hours worked, subtract the start time from the end time and take off unpaid breaks. 9:00 am to 5:30 pm is 8 hours 30 minutes; minus a 30-minute break, that is 8 hours, or 8.00 decimal hours.
How to use the hours calculator
- Enter a start and end time. If the end time is earlier than the start, the calculator assumes the shift ran past midnight.
- Enter any unpaid break in minutes.
- For a whole week, fill in the time card. Days left blank are skipped.
- Add your hourly rate to estimate pay. Hours over the overtime limit (40 by default) are paid at 1.5 times the rate, the US federal standard for non-exempt workers.
- Click Copy time card to paste it into Excel or Google Sheets.
Converting minutes to decimal hours
Payroll systems use decimal hours, so 7 hours 45 minutes is 7.75 hours, not 7.45. Divide the minutes by 60:
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 5 | 0.08 | 35 | 0.58 |
| 10 | 0.17 | 40 | 0.67 |
| 15 | 0.25 | 45 | 0.75 |
| 20 | 0.33 | 50 | 0.83 |
| 25 | 0.42 | 55 | 0.92 |
| 30 | 0.50 | 60 | 1.00 |
Overnight shifts
For a shift from 10:00 pm to 6:30 am, the calculator adds 24 hours to the end time, giving 8 hours 30 minutes. Shifts longer than 24 hours aren’t supported, so split them into days.
Tips for accurate timesheets
- Record times as you go rather than from memory at the end of the week.
- Check your employer’s rounding rule; some round to the nearest 15 minutes.
- Paid breaks (usually short rest breaks) shouldn’t be subtracted; unpaid meal breaks should.
- Overtime rules vary by country and state, and some states, such as California, also have daily overtime.
