How this US Time Zone Converter works — 2026 guide
The contiguous US spans four time zones — Eastern, Central, Mountain, and Pacific — each one hour apart, plus Alaska and Hawaii-Aleutian for the full set of six. This US time zone converter translates any time across all six zones with automatic daylight saving handling (DST runs from the second Sunday in March to the first Sunday in November; most of Arizona stays on Mountain Standard Time year-round). Whether you're scheduling a remote meeting from New York to Los Angeles or confirming a 9 AM ET conference call for your PT team, the answer is one input away.
How to use it in 3 steps
- Enter a time and pick the source US time zone (ET, CT, MT, PT, AKT, or HST).
- Choose the target zone — or "all zones" to see every conversion at once.
- Read the converted times with DST applied automatically based on the date.
