UTC Time Converter
Convert UTC to EST, PST, IST, GMT, AEST, and 30+ time zones. Includes offset table, worked examples, and daylight saving time guide.
UTC (Coordinated Universal Time) is the world's primary time standard. To convert UTC to a local time, add or subtract the local UTC offset. For example, New York (EST) is UTC−5, so 14:00 UTC = 09:00 EST. UTC does not change with daylight saving time.
What Is UTC?
UTC stands for Coordinated Universal Time. It is the international time standard that all other time zones are offset from. UTC replaced GMT (Greenwich Mean Time) as the world standard in 1960, though for everyday purposes the two are functionally equivalent.
Key facts:
- UTC does not observe daylight saving time (DST)
- All time zones are expressed as UTC+ or UTC− an offset in hours and minutes
- Computer systems, aviation, military, and financial markets use UTC to avoid DST confusion
- UTC is also written as Z (Zulu time) in aviation and military contexts
How to Convert UTC to Local Time
Formula:
Local Time = UTC Time + UTC Offset
Examples:
| Location | UTC Offset | UTC 14:00 = Local Time |
|---|---|---|
| London (GMT/BST) | UTC+0 / UTC+1 | 14:00 / 15:00 |
| New York (EST/EDT) | UTC−5 / UTC−4 | 09:00 / 10:00 |
| Los Angeles (PST/PDT) | UTC−8 / UTC−7 | 06:00 / 07:00 |
| Mumbai (IST) | UTC+5:30 | 19:30 |
| Sydney (AEST/AEDT) | UTC+10 / UTC+11 | 00:00 next day |
| Tokyo (JST) | UTC+9 | 23:00 |
| Berlin (CET/CEST) | UTC+1 / UTC+2 | 15:00 / 16:00 |
| Dubai (GST) | UTC+4 | 18:00 |

| UTC+1 | Central European Time (CET) | UTC+1 | Yes → UTC+2 CEST |
| UTC+3 | Moscow Time (MSK) | UTC+3 | No |
| UTC+4 | Gulf Standard Time (GST) | UTC+4 | No |
| UTC+5:30 | India Standard Time (IST) | UTC+5:30 | No |
| UTC+8 | China Standard Time (CST) | UTC+8 | No |
| UTC+9 | Japan Standard Time (JST) | UTC+9 | No |
| UTC+10 | Australian Eastern Standard Time (AEST) | UTC+10 | Yes → UTC+11 AEDT |
FAQ
Is UTC the same as GMT?
For practical purposes, yes — UTC+0 and GMT are the same time. The technical difference is that GMT is based on the Earth's rotation (astronomical), while UTC is based on atomic clocks. In everyday scheduling, travel, and computing, the two can be used interchangeably.
How do I convert UTC to EST?
Subtract 5 hours from UTC during standard time, or subtract 4 hours during daylight saving time (EDT). UTC 12:00 = EST 07:00. EST is observed November to March; EDT (UTC−4) is observed March to November.
Why do computers use UTC?
Computers store timestamps in UTC to avoid confusion caused by daylight saving time changes and different local time zones. When you see a Unix timestamp (e.g. 1750000000), it represents the number of seconds since January 1, 1970, 00:00:00 UTC.
What does UTC+0 mean?
UTC+0 means no offset from Coordinated Universal Time. Locations on UTC+0 include Reykjavik (Iceland), Accra (Ghana), and the UK during winter (GMT). The UK moves to UTC+1 (BST) in summer.
Does UTC change with daylight saving time?
No. UTC never changes. Daylight saving time is applied by adjusting the local UTC offset — for example, the UK moves from UTC+0 (winter) to UTC+1 (summer BST). UTC itself remains constant year-round.
