Hours Calculator
Hours between two times, and the week that totals from them.
Add up hours worked from start and end times, with breaks and overtime. Shows hours and minutes alongside decimal hours, because payroll needs the second one.
| Day | Start | End | Break | Worked |
|---|---|---|---|---|
| Monday | 7:307.5 | |||
| Tuesday | 7:307.5 | |||
| Wednesday | 7:307.5 | |||
| Thursday | 7:307.5 | |||
| Friday | 7:307.5 | |||

Times can be written 9:00, 0900, 9am or 9.00. Leave a day blank if it was not worked. A finish time earlier than the start is read as a shift running past midnight and marked +1d.
Both figures say the same thing. The first is how people write hours down, the second is what payroll multiplies by a rate, and they are not interchangeable: seven hours forty-five minutes is 7.75, never 7.45.
Forty hours is the US federal threshold under the Fair Labor Standards Act. Plenty of places use a daily threshold instead, or a different weekly one, so check what actually applies to you.
How the Hours Calculator works
Enter start and end times for each day, take off unpaid breaks, and get the week both ways: hours and minutes as you would write them down, and decimal hours as payroll multiplies them. A finish time earlier than the start is read as a shift running past midnight rather than as a negative day, which is the thing that breaks most timesheet tools.

Frequently asked questions
Why show decimal hours as well as hours and minutes?
Because they are different numbers for the same thing and mixing them costs money. Seven hours and forty-five minutes is 7.75 decimal hours, not 7.45. Writing 7.45 on a timesheet loses eighteen minutes of pay a shift, and it happens constantly because both look like perfectly ordinary numbers.
How do I enter a night shift?
Normally. A finish time earlier than the start is taken as running past midnight, so 22:00 to 06:00 comes out as eight hours and is marked +1d. Reporting minus sixteen hours, which is what subtracting naively gives, is the behaviour that makes people abandon a timesheet tool.
What time formats can I type?
9:00, 0900, 9am, 9.00 and 09:00 all work, in either case, with or without a space before am or pm. A timesheet gets filled in quickly and refusing 9.30am helps nobody.
When does overtime start?
Forty hours a week is the US federal threshold under the Fair Labor Standards Act, and it is the default here. Plenty of places use a daily threshold instead, or a different weekly one, so the figure is adjustable and you should check what actually applies to you.
Are breaks paid?
The break minutes entered here come off the total, so they are treated as unpaid. Paid breaks simply need not be entered.
