Quick Answers

Is the calculator really free?

Yes — every calculator is free with no limits and no account.

Can I use it for commercial purposes?

Yes. Use the results for payroll, invoices, scheduling or any other business purpose.

Do you store my calculation data?

No. Calculations run in your browser, so we never receive the times or dates you enter.
