US time zone converter
Pick a date, a time, and the zone it is in — see the same moment in every US time zone, with daylight saving applied for that exact date.
Convert a time

Differences between DST-observing zones never change, but Arizona and Hawaii stay on standard time — so pick a summer date and a winter date to see their gap to the mainland shift by an hour. Dates are listed on the DST calendar.

Frequently asked questions
How do I convert Eastern Time to Pacific Time?
Subtract 3 hours: 12:00 PM ET is 9:00 AM PT, all year. See the EST to PST chart.
Does the converter handle daylight saving time?
Yes. It uses your browser's built-in IANA time zone database, so a date in July converts with EDT, CDT, MDT, PDT, and AKDT, while Arizona and Hawaii stay on standard time.
What happens to times that fall inside a DST change?
On the second Sunday of March, 2:00–2:59 AM does not exist in DST-observing zones; the converter moves such times forward one hour. On the first Sunday of November, 1:00–1:59 AM happens twice, and the converter uses the first occurrence (daylight time).
