Working Hours Calculator
Add your shifts and breaks to calculate total hours worked. Handles overnight shifts too.
How the Working Hours Calculator Works
Tracking working hours accurately is essential for freelancers, contractors, part-time workers, and anyone managing timesheets. Our calculator lets you add multiple time entries — each with a start time, end time, and optional break duration — and totals everything up instantly.
It handles overnight shifts (where the end time is before the start time), deducts breaks automatically, and gives you a clear summary of total hours, total minutes, and a per-entry breakdown. Everything runs locally in your browser.
How does the working hours calculator work?
Add one or more time entries with a start time, end time, and optional break duration. The calculator totals your hours and minutes worked across all entries.
Can I add multiple shifts?
Yes. Click "Add Entry" to add as many shifts or days as you need. Each entry has its own start time, end time, and break field. The total updates automatically.
Does it handle overnight shifts?
Yes. If the end time is earlier than the start time, the calculator assumes the shift crosses midnight and calculates accordingly.
Is my data stored?
No. All calculations happen in your browser. Your time entries are never sent to any server.
