Frequently Asked Questions
Answers about how DateToolsHQ works, calculator accuracy, holidays, and when results are appropriate to rely on.

- Yes. All calculators on DateToolsHQ are free to use. We do not require an account or payment to run a calculation.
- Are the calculators accurate?
- Each tool follows documented rules on its page, such as UTC calendar math or optional holiday lists. Results are estimates for planning. Double-check important dates and amounts with your own records or official sources.
- Do the tools account for holidays?
- Business and working day calculators can exclude weekends and, where noted, sample holiday lists. Country and year pages show simplified national holiday calendars. Employer, regional, and contract rules may differ.
