Useful next steps

Unix timestamp converter

Seconds versus milliseconds, UTC/local zones and explicit out-of-range handling.

Time duration

Start/end times, crossing midnight, breaks, decimal hours and explicit timezone handling.

Date difference

Inclusive/exclusive counting, leap years, calendar dates versus elapsed time.

Working with time zone converter

Date calculations can depend on calendar rules, time zones and whether endpoints are included. A duration in hours is different from a number of calendar days when daylight-saving changes occur.

Common questions

Are all days exactly 24 hours long?

Elapsed time across a daylight-saving transition can differ from a simple calendar-day count. Use the measure relevant to your schedule.

Why can the same timestamp show different dates?

A timestamp represents an instant, while a calendar date is interpreted in a time zone. Near midnight, the same instant can fall on different local dates.
