Work Hours Calculator
Enter your time in/out for each day and optional break time. Get daily hours, weekly total, and pay.
Tip: You can enter overnight shifts. For example, 22:00–03:00 or 10:00 PM–3:00 AM.
Hours are shown in decimal format (industrial hours).
How this work hours calculator works
Enter your time in and time out for each day of the week, then add optional break time. The calculator subtracts breaks and shows your daily total in two formats: decimal hours (industrial hours) and a readable HH:MM format. Your weekly total and daily average are calculated automatically. Overnight shifts are supported: if your time in is later than your time out (for example 10:00 PM to 3:00 AM), the calculator treats it as a shift that crosses midnight and calculates the correct hours.
If you enter an hourly rate, the tool estimates your total weekly pay based on your total hours. You can switch between 24-hour time and AM/PM format depending on what you prefer.

FAQ
What is a work hours calculator?
A work hours calculator helps you calculate how many hours you worked each day and in total for the week based on your time in, time out, and break time.
Can I enter time in 12-hour (AM/PM) format?
Yes. Use the AM/PM mode to enter hours and minutes with AM or PM. You can also switch to 24-hour mode if you prefer.
How do I enter break time?
You can enter break time either as minutes (for example 30) or as hours and minutes (for example 0:30). The break will be subtracted from your daily total.

Decimal hours show time as a single number. For example, 7 hours 30 minutes becomes 7.5. This is commonly used for timesheets and payroll calculations.
