How to Use the Hours Calculator

Features
Parses 24-hour time inputs, correctly rolls over midnight for night shifts, subtracts break time, and presents results in the three formats payroll systems expect.
Benefits & Use Cases
Hourly workers verify paychecks, freelancers log billable time, and managers total team hours without spreadsheet formulas.
Tips
Decimal hours (e.g. 7.5) is what most payroll software wants — the tool computes it for you. Double-check AM/PM if your device uses 12-hour entry.
Frequently Asked Questions
How are overnight shifts handled?
If clock-out is earlier than clock-in, the tool assumes the shift crossed midnight and adds 24 hours.
What format are times entered in?
Your browser’s native time picker — usually 12-hour with AM/PM or 24-hour depending on device settings.
Are breaks paid or unpaid?
The break field subtracts unpaid break minutes; if your breaks are paid, leave it at zero.
What are decimal hours?
Hours expressed as a decimal (7h 30m = 7.5h) — the format payroll and invoicing systems typically require.
