Disclaimer

The calculators on this site perform standard calendar and clock arithmetic. While we test them carefully, results are provided “as is” — for payroll, legal deadlines or other consequential uses, always double-check results against your employer's or institution's official rules (time zones, rounding policies and local regulations can affect real-world outcomes).

Accuracy of results

We test every calculator against reference values and review our formulas regularly. However, results depend entirely on the numbers and assumptions you enter, and simplified models cannot capture every real-world factor. Use the results as a starting point, not a final answer.
