About Time calculators
Time calculators answer questions calendars make awkward: exact age, duration between dates, or how deadlines shift when you add working days. They reduce off-by-one mistakes and timezone confusion for straightforward cases.
For legal deadlines or contract clocks, always confirm rules with authoritative sources—holidays and business-day definitions vary.
Common use cases
- Precise age and elapsed time for planning milestones
