How it works
- The page reads your browser clock to display the current local time.
- New York follows Eastern Time: UTC-5 (EST) in winter and UTC-4 (EDT) in summer.
- Tehran follows Iran Standard Time (IRST, UTC+3:30) throughout the year; Iran abolished daylight saving time in 2022.
- Iran uses a non-standard 30-minute offset, so Tehran is 7.5 hours ahead of New York during EDT and 8.5 hours ahead during EST.
- Enter a time in either city to instantly see the equivalent time in the other.
Use cases
- Schedule a video call between a New York office and colleagues in Tehran.
- Check whether Tehran business hours overlap with your New York workday.
- Convert a Tehran meeting invite to New York local time.
- Plan international calls without doing the half-hour offset math manually.
- Verify what time it is in Tehran before messaging a contact there.
- Coordinate project deadlines across the ET and IRST time zones.
