Frequently Asked Questions
How do I convert EST to PST?↓
Set the 'From' zone to America/New_York (EST/EDT) and the 'To' zone to America/Los_Angeles (PST/PDT), then enter your date and time. The converted time appears instantly. EST is UTC−5 and PST is UTC−8, so PST is 3 hours behind EST.
Does the converter handle daylight saving time?↓
Yes. The converter uses the browser's built-in Intl.DateTimeFormat API, which applies IANA tz database rules and correctly handles all DST transitions for every supported time zone.
What time zones are supported?↓
All 600+ IANA time zones are supported, including America/New_York, Europe/London, Asia/Tokyo, Australia/Sydney, and all region-specific zones. You can also search by city or abbreviation.
What is the difference between UTC and GMT?↓
UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are effectively the same offset (UTC+0), but UTC is the international standard used for timekeeping, while GMT is the historical civil time zone for the UK. For practical purposes they can be used interchangeably.
How many hours ahead is Tokyo compared to New York?↓
Tokyo (Asia/Tokyo, JST, UTC+9) is typically 13 or 14 hours ahead of New York (America/New_York, EST UTC−5 / EDT UTC−4), depending on whether daylight saving time is in effect in New York.
