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 |
| CET / CEST | Central European (Summer) Time | UTC +1 / +2 | Paris, Berlin, Amsterdam — EU business core |
| IST | India Standard Time | UTC +5:30 | India — major IT & outsourcing region |
| CST | China Standard Time | UTC +8 | Beijing, Shanghai — East Asia business hub |
| 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 BST and AKST?
British Summer Time (BST) is UTC+1, while Alaska Standard Time (AKST) is UTC-9. BST is 10 hours ahead of AKST. This means when it's 6:00 PM in BST, it's 8:00 AM in AKST. AKST is used during winter months in Alaska (November to March).
What's the difference between AKST and AKDT?
Alaska Standard Time (AKST) is UTC-9 and is used during winter months (November to March). Alaska Daylight Time (AKDT) is UTC-8 and is used during summer months (March to November). When Alaska is in AKDT (summer), the time difference from BST becomes 9 hours instead of 10. Always verify which is active when scheduling.
When should I use the BST to AKST converter?
Use this converter when coordinating with Alaska during winter months (November to March) when AKST is active. Alaska includes Anchorage, Juneau, and Fairbanks. During summer months when AKDT is active, use the BST to AKDT converter for more accurate times.
What are the major cities in the AKST timezone?
Major cities in Alaska Standard Time include Anchorage (largest city), Juneau (state capital), Fairbanks, Ketchikan, and Sitka. Alaska has significant oil and gas industries, salmon fishing, tourism, and natural resource extraction. The state is also strategically important for North American defense and Arctic region interests.
How do I convert BST to AKST manually?
To convert from BST to AKST, subtract 10 hours from the BST time. For example, if it's 6:00 PM BST, it would be 8:00 AM AKST. Remember this only applies during winter months when Alaska uses AKST. During summer when Alaska observes AKDT, the difference is 9 hours instead. Always check the current date to use the correct conversion.
What should I know about scheduling across BST and AKST?
The UK and Alaska have significant time differences. Morning BST times (8-10 AM) correspond to very early morning AKST (10 PM-12 AM previous evening), making synchronous morning meetings extremely challenging. Afternoon BST (2-4 PM) roughly aligns with early morning AKST (4-6 AM), still quite early. Late afternoon UK times (5-6 PM BST) work better for mid-morning AKST (7-8 AM). Successful scheduling requires substantial flexibility and often means one party works outside normal business hours.
Pro Tips
- • BST is 10 hours ahead of AKST during winter months (November-March). Remember to switch to the BST to AKDT converter when summer daylight saving time is active.
- • The UK observes daylight saving time with different dates than Alaska. UK changes: last Sunday of March/October. Alaska: second Sunday of March/first Sunday of November.
- • Early morning BST (8-10 AM) equals late evening previous day AKST (10 PM-12 AM). This makes synchronous morning meetings across these timezones extremely difficult.
- • Late afternoon BST (5-6 PM) roughly aligns with early morning AKST (7-8 AM), which is the most practical window for transatlantic scheduling to Alaska.
- • Alaska is 3 hours behind Pacific time (PST/PDT), so when coordinating with both US West Coast and Alaska, plan carefully for the 3-hour gap.
- • Anchorage is Alaska's largest city and business hub. Alaska has significant oil, gas, and fishing industries, making proper timezone coordination crucial for international operations.
