## Tools to calculate dates, durations and schedules

Dates and schedules often look simple until weekends, midnight crossings or calendar rules are involved. These tools make time intervals explicit so you can plan with fewer manual checks.

Check the selected dates, timezone and break settings before relying on a result. A small assumption can change a deadline, a worked-hours total or an arrival time.
