✅ Hours Calculator
Timesheets are just seven small subtractions plus one addition — but across a week of split shifts the arithmetic gets tedious. Enter each day's start and end time; empty days are skipped automatically.
The total is shown in decimal hours (e.g. 37.5), the format payroll systems expect. Overnight shifts crossing midnight are handled too.
How to use this calculator
Enter your start and end times for each day of the week and the calculator totals your work hours, showing a per-day breakdown and a weekly total in decimal hours.
- Fill in the start and end fields for each day you worked, for example Monday - start and Monday - end.
- Leave any day fully blank if you did not work that day; empty days are skipped.
- Check the per-day row to confirm each day's hours look right.
- Use the hero total at the top, shown in decimal hours, for your timesheet or payroll entry.
Frequently asked questions
What does the Hours Calculator compute?
It takes the start and end times for each day from Monday through Sunday and totals your weekly work hours. You get a row per day plus a hero total, and the total is expressed in decimal hours such as 37.5, the format payroll systems expect.
How does it handle a shift that crosses midnight?
If the end time is earlier than the start time, the calculator treats the shift as running into the next day. A 22:00 start with a 06:00 end counts as 8 hours, which covers night-shift timesheets without extra steps.
Can you give a worked example?
Enter 09:00 to 17:30 for Monday through Friday and leave the weekend blank. Each weekday row shows 8.5 h and the weekly total comes to 42.5 hours.
What should I know about accuracy?
Results are exact to the minute based on what you enter, and days with only one time entered are skipped. The tool does not subtract unpaid breaks or add overtime rates, so apply those to the decimal total yourself if your employer requires it.
