Daylight-saving time change calculator

Daylight-saving transitions are seasonal The selected timezone and year determine whether clocks move forward, move backward, or do not change at all. A forward transition can skip a local hour, while a backward transition can repeat one. Rules are not synchronized across every country.

How to use this result

Choose the actual date, local time, and named IANA timezone. Review the UTC offsets and any date rollover before sharing a meeting, travel, support, or project schedule. A timezone result is a planning aid, not a replacement for an official regional calendar, employment policy, or contractual rule.

Important edge cases

Check daylight-saving transitions, locations without DST, unusual offsets, midnight boundaries, weekends, and public holidays. When the answer matters, communicate the full local date and timezone rather than only a clock value.
