How to choose a calculator

Start with the kind of answer you need: calendar-day arithmetic, working days and holidays, a live event countdown, a regional holiday rule, a time-zone conversion, an exact age calculation, or an explanation of calendar conventions. Each linked tool explains its assumptions and processes the calculation in your browser.

Plan with the right date convention

Calendar results can change when leap years, month lengths, weekends, public holidays, observed dates, daylight-saving transitions, or midnight rollovers matter. Review the explanation on the selected page and confirm important legal, employment, travel, or official dates with the relevant authority.
