What is Work Hours Calculator?
A work hours calculator adds up your daily start and end times, subtracts break time, and totals your hours across the week. It's useful for freelancers tracking billable hours, employees filling out timesheets, or anyone managing a flexible schedule.
How to use
- 1 Each row represents one work day. Enter the start time, end time, and break duration in minutes.
- 2 Click 'Add day' to add more rows (up to 7 days).
- 3 Results update automatically as you type.
- 4 The summary shows hours per day, total weekly hours, and total minutes.
Formula
Example calculation
Working 9:00 AM to 5:30 PM with a 45-minute break gives 7.75 hours (7 hours 45 minutes). Five such days totals 38.75 hours for the week.
Frequently asked questions
Can I track overnight shifts?
If the end time is earlier than the start time the calculator treats it as crossing midnight and adds 24 hours to the end time automatically.
How are partial hours shown?
Hours are displayed as decimal (e.g. 7.75) and also as hours and minutes (e.g. 7h 45m) for clarity.
