Top 10 Most Common Time Zones
| Abbreviation | Full Name | UTC Offset | Typical Use |
|---|---|---|---|
| UTC | Coordinated Universal Time | UTC ±0 | Global reference standard (servers, logs, APIs) |
| EST / EDT | Eastern (US) Time | UTC −5 / −4 | New York, Toronto — North American business hub |
| CST / CDT | Central (US) Time | UTC −6 / −5 | Chicago, Dallas — US central business region |
| PST / PDT | Pacific (US) Time | UTC −8 / −7 | San Francisco, Los Angeles — tech industry standard |
| GMT / BST | Greenwich Mean / British Summer Time | UTC 0 / +1 | UK, used globally as a reference with UTC |

| JST | Japan Standard Time | UTC +9 | Tokyo — finance & tech hub |
| AEST / AEDT | Australian Eastern (Daylight) Time | UTC +10 / +11 | Sydney, Melbourne — APAC regional business |
Why Time Zone Abbreviations Are Ambiguous
Unlike standardized identifiers (like America/New_York or Europe/London from the IANA tz database), abbreviations such as "CST" or "IST" are not globally unique. They can refer to different time zones depending on context — country, region, or even time of year (due to daylight saving time).
Common Ambiguous Time Zone Abbreviations
| Abbrev. | Common Meaning(s) | UTC Offset | Region(s) |
|---|---|---|---|
| CST | Central Standard Time / China Standard Time / Cuba Standard Time | UTC−6 / UTC+8 / UTC−5 | North America, China, Cuba |
| IST | Indian Standard Time / Irish Standard Time / Israel Standard Time | UTC+5:30 / UTC+1 / UTC+2 | India, Ireland, Israel |
| AST | Atlantic Standard Time / Arabia Standard Time | UTC−4 / UTC+3 | Caribbean, Canada, Middle East |
| PST | Pacific Standard Time / Philippine Standard Time | UTC−8 / UTC+8 | North America, Philippines |
| EST | Eastern Standard Time (North America / Australia) | UTC−5 / UTC+10 | North America, Australia |
✅ Best Practice
To avoid ambiguity, always:
- Use IANA tz identifiers — e.g.,
America/New_Yorkinstead of "EST" - Specify UTC offset explicitly — e.g.,
UTC−5when abbreviations must be used - Include the full timezone name — e.g., "Eastern Standard Time (EST)" with UTC offset

Frequently Asked Questions
What is the time difference between AKST and GMT?
Alaska Standard Time (AKST) is UTC-9, while GMT (Greenwich Mean Time) is UTC+0, making GMT 9 hours ahead of AKST. When it is 12:00 PM (noon) in Alaska (AKST), it is 9:00 PM the same day in London (GMT).
How does AKST differ from AKDT?
AKST (Alaska Standard Time) is UTC-9 and is observed during standard time (November to March), while AKDT (Alaska Daylight Time) is UTC-8 and is observed during daylight saving time (March to November). This one-hour difference is important when scheduling across seasons in Alaska.
Does GMT observe daylight saving time?
No, GMT (Greenwich Mean Time) does not observe daylight saving time year-round. However, the UK uses BST (British Summer Time) during daylight saving periods (late March to late October). GMT remains UTC+0 and serves as a global standard reference throughout the year.
When does AKST change to AKDT?
Alaska Standard Time (AKST) transitions to Alaska Daylight Time (AKDT) on the second Sunday in March at 2:00 AM. The reverse transition from AKDT to AKST occurs on the first Sunday in November at 2:00 AM. During AKDT, the time difference with GMT is only 8 hours instead of 9.
How do I convert AKST to GMT manually?
To convert AKST to GMT, simply add 9 hours to the AKST time. For example, if it is 3:00 PM AKST, the corresponding GMT time would be 12:00 AM (midnight) the next day (15:00 + 9 hours = 24:00 or 00:00). If the result exceeds 24 hours, subtract 24 hours and add 1 day.
Why is understanding AKST to GMT conversion important?
Understanding AKST to GMT conversion is crucial for coordinating with teams in Alaska and the UK/Europe, international travel planning, virtual meetings across vast time zones, and managing global business operations. The 9-hour difference makes accurate conversion essential for scheduling and business coordination.
Pro Tips
- • AKST is observed from November to March. From March to November, Alaska uses AKDT (Alaska Daylight Time) with an 8-hour difference from GMT.
- • GMT is equivalent to UTC (Coordinated Universal Time) and serves as the global reference time used for aviation and international business.
- • The UK switches to BST (British Summer Time) at different dates than Alaska switches to AKDT, so the time difference can vary by a few weeks during transition periods.
- • When scheduling international meetings between Alaska and UK, early morning AKST (7-8 AM) aligns with 4-5 PM GMT the same day, making it ideal for both regions during winter.
- • Use a converter like this one for daylight saving transitions to avoid miscalculations when AKST switches to AKDT and GMT switches to BST.
- • Alaska spans multiple time zones - while Anchorage uses AKST, some regions use other time zones. Always verify which Alaska time zone applies to your contact location.
