Timezone Converter

Free Timezone Converter — Convert Time Between 50+ World Time Zones

Time zones are one of the most frustrating parts of working across international borders. You are scheduling a call with a client in London, a developer in Bangalore, and a team member in San Francisco. Getting the time right for all three of them requires converting between EST, IST, and GMT simultaneously. One mistake and someone misses the meeting.

This free Timezone Converter makes that easy. Enter a date and time in any time zone and instantly see what time it is in another location. The tool covers 50+ time zones across every region of the world — from UTC and GMT to IST, JST, AEST, and everything in between. Live clocks show you the current local time in eight major cities, updating every second so you always know what time it is right now without doing any math.

There is no account to create, no app to install, and no limits. Everything runs locally in your browser. The timezone reference table at the bottom lists every supported time zone with its UTC offset and region, so you can quickly check an unfamiliar abbreviation without leaving the page.

Whether you are coordinating a remote team, booking flights, scheduling an international webinar, or just curious what time it is on the other side of the world, this timezone converter gives you an accurate answer in seconds.

Understanding Time Zones

A time zone is a region of the world that observes a uniform standard time for all legal, commercial, and social purposes. Time zones are expressed as UTC offsets — the difference in hours (and sometimes minutes) from Coordinated Universal Time (UTC), which is the primary time standard by which the world regulates clocks.

The International Date Line runs through the Pacific Ocean. Moving west from UTC, time zones go backward (UTC-1, UTC-2, and so on down to UTC-12). Moving east, they go forward (UTC+1, UTC+2, and so on up to UTC+14). This is why it can be yesterday in Honolulu while it is tomorrow in Auckland, even though they are on the same planet at the same instant.

Some countries use half-hour offsets. India (IST) is UTC+5:30. Nepal (NPT) uses UTC+5:45, one of the few quarter-hour offsets in the world. Australia's Northern Territory observes ACST at UTC+9:30. This tool correctly handles all of these fractional offsets, so your conversions are always accurate.

Daylight Saving Time (DST) complicates matters further. Many countries (including most of the USA, Canada, and Europe) shift their clocks forward by one hour in spring and back in autumn. The US EDT (Eastern Daylight Time) is UTC-4, while EST (Eastern Standard Time) is UTC-5. This tool provides both as separate entries, so you can select the correct one for the time of year you are converting.
