U.S. time zones and daylight saving
Choose a date as well as a time: U.S. daylight saving time changes the offset for many locations during the year. This converter uses the browser’s IANA time-zone data, including the selected zone’s date-specific offset. Arizona and Hawaii follow different daylight-saving rules from most states.
If a local time falls inside the spring clock-change gap or the repeated fall hour, confirm the intended time with the meeting organizer.
No location permission is needed. Conversion happens in your browser.
Frequently asked questions
Does it account for daylight saving time?
Yes. It uses the selected IANA time zone and the date you enter to determine the applicable offset.
Why does the result change when I change the date?
Some locations switch between standard time and daylight time on different dates, so the offset between them can change.
