About these tools

Solve common calendar and scheduling questions without manual date counting. Calculate an exact age, measure the duration between dates, exclude weekends and holidays, or compare meeting times across multiple time zones.

Date calculations can depend on time zones, daylight-saving transitions, inclusive counting rules, and custom weekend definitions. Review the selected settings whenever a result is used for travel, payroll, contracts, or deadlines.
