Common Timezone Abbreviations

The world is divided into 24 main time zones, each one hour apart. Here are some of the most frequently used:

• UTC — Coordinated Universal Time (also called GMT or Zulu time); the global standard
• EST/EDT — Eastern Time (USA/Canada); EST is 5 hours behind UTC, EDT is 4 hours behind
• CST/CDT — Central Time (USA/Canada); CST is 6 hours behind UTC, CDT is 5 hours behind
• PST/PDT — Pacific Time (USA/Canada); PST is 8 hours behind UTC, PDT is 7 hours behind
• GMT/BST — Greenwich Mean Time (UK); GMT is the same as UTC, BST is 1 hour ahead
• CET/CEST — Central European Time; CET is 1 hour ahead of UTC, CEST is 2 hours ahead
• IST — Indian Standard Time; 5.5 hours ahead of UTC
• JST — Japan Standard Time; 9 hours ahead of UTC
• AEST — Australian Eastern Standard Time; 10 hours ahead of UTC

When You Need a Timezone Converter

• Scheduling meetings — Find a time that works for colleagues across multiple continents

• Shipping and delivery — Check estimated arrival times across timezone boundaries

Daylight Saving Time

Many regions observe Daylight Saving Time (DST), where clocks "spring forward" an hour in spring and "fall back" an hour in autumn. This tool uses standard abbreviations; for precise conversions during DST transitions, it's best to reference official timezone databases. If you're planning critical meetings during DST changeover periods, add extra verification.

Frequently Asked Questions

What's the difference between UTC and GMT?

UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are essentially the same thing for practical purposes, though UTC is the more modern standard used in technical and scientific contexts. Both refer to the time at the Prime Meridian with no offset.

Why do some timezones have half-hour or quarter-hour offsets?

A few regions use non-standard offsets for historical or geographical reasons. For example, India uses IST (UTC+5:30), Nepal uses NPT (UTC+5:45), and some Australian states use unique offsets. This tool includes the most common hour-based offsets; for precise work with unusual timezones, consult a timezone database.

Do you account for Daylight Saving Time?

This tool uses standard timezone abbreviations. During DST transitions, the actual offset may change. For official, up-to-date DST rules, check your region's government or meteorological authority.

Can I compare more than two timezones?

Yes! Click Add Another Timezone to add additional comparison pairs. This is useful for coordinating across multiple regional offices or international teams.

What if my timezone isn't in the list?

This tool includes the most commonly used timezones. If you need a timezone not listed, use the UTC offset to calculate manually: add or subtract the hours from UTC to get your local time. For a complete timezone database, consider a Countdown Timer that factors in specific timezone rules, or use a tool like Work Days Calculator for business scheduling.
