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 |

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

About EET to AST Time Conversion
Converting time between Eastern European Time (EET) and Atlantic Standard Time (AST) is essential for coordinating between Eastern Europe and Atlantic Canada. EET is UTC+2 (during winter, typically November to March) and UTC+3 during daylight saving time (EEST), while AST is UTC-4 (standard time, typically November to March). EET is 6 hours ahead of AST during winter months. When daylight saving time is active on both sides, the difference can vary based on transition dates.
This conversion is crucial for Eastern European companies coordinating with Atlantic Canada offices in Halifax, St. John's, and other major cities. Software development teams, telecommunications firms, and enterprises bridging Eastern Europe and Atlantic Canada operations rely on accurate time conversions. Eastern European Time remains consistent during winter, but transitions to EEST (UTC+3) on the last Sunday of March. Atlantic Canada transitions to ADT on the second Sunday of March and back to AST on the first Sunday of November.
Common Use Cases for EET to AST Conversion
Business & Work
- Scheduling calls between Eastern European offices and Atlantic Canada headquarters
- Coordinating software development teams across Eastern Europe and Atlantic Canada
- Managing business process outsourcing operations with Atlantic Canada clients
- Planning conference calls for telecommunications and offshore industry operations
Personal & Travel
- Coordinating with family and friends in Atlantic Canada
- Planning travel between Eastern Europe and Atlantic Canada destinations
- Scheduling virtual meetings with Atlantic Canada relatives or business partners
- Arranging online collaboration with Atlantic Canada-based colleagues

Quick Reference: EET to AST
Remember: EET is 6 hours ahead of AST during winter. When daylight saving time is active, the difference may vary based on transition dates between regions. Europe changes to EEST on the last Sunday of March, while Atlantic Canada transitions ADT on the second Sunday of March.
Frequently Asked Questions
What is the time difference between EET and AST?
Eastern European Time (EET) is UTC+2 (winter) or UTC+3 (summer with EEST), while Atlantic Standard Time (AST) is UTC-4. During winter months when EET is UTC+2, EET is 6 hours ahead of AST. During summer months when EEST is UTC+3, EET is 7 hours ahead of AST.
How does the EET to AST offset differ from other North American timezones?
AST is 1 hour behind EST (Eastern Standard Time) and 3 hours ahead of PST (Pacific Standard Time). Since EET is 6 hours ahead of AST during winter, it's 7 hours ahead of EST and 3 hours ahead of PST. AST represents Atlantic Canada and part of the Caribbean during standard time.
What is the time difference between EET and ADT?
When daylight saving time is active in Atlantic Canada, AST becomes ADT (Atlantic Daylight Time, UTC-3). During these months (March-November), EET (UTC+2) is 5 hours ahead of ADT during winter, and EEST (UTC+3) is 6 hours ahead of ADT during summer. The offset varies depending on which regions are observing daylight saving.
When is the best time for calls between Eastern Europe and Atlantic Canada?
Business hour overlap is limited due to the 6-7 hour difference. Early morning in Eastern Europe (7-9 AM EET) overlaps with late evening in Atlantic Canada (1 AM-3 AM AST). Evening in Eastern Europe (6-8 PM EET) overlaps with early morning in Atlantic Canada (12 PM-2 PM AST). These windows offer minimal but manageable overlap.
Why do businesses coordinate between Eastern Europe and Atlantic Canada?
Atlantic Canada is an important business region with presence in finance, telecommunications, and offshore industries. Eastern European countries have significant IT talent and outsourcing capabilities. The 6-7 hour offset enables operations when teams are split between regions. Companies benefit from talent pools and cost advantages.
How do daylight saving transitions affect EET to AST coordination?
Europe transitions to EEST on the last Sunday of March, while Atlantic Canada transitions to ADT on the second Sunday of March (earlier). Europe transitions back to EET on the last Sunday of October, while Atlantic Canada transitions back to AST on the first Sunday of November (later). During these transition weeks, the offset can be 5, 6, 7, or 8 hours.
Pro Tips
- • EET transitions to EEST on the last Sunday of March, while AST transitions to ADT on the second Sunday of March. Mark both dates to avoid scheduling confusion during spring transitions.
- • The 6-7 hour offset is significant - a 9 AM EET meeting is 2 AM or 3 AM AST. Consider asynchronous communication like email, Slack, or recorded videos for non-urgent matters.
- • Schedule Eastern Europe morning meetings (7-9 AM EET) for Atlantic evening slots (1 AM-3 AM AST) to maintain work-life balance on both sides.
- • For urgent discussions, use the 12-2 PM AST window (6 PM-8 PM EET) when both teams can briefly connect during work hours.
- • During spring (late March to early November), EET/EEST is 6-7 hours ahead of ADT. Adjust meeting times accordingly after both regions switch to daylight saving time.
- • Document all meeting times in both EET and AST to prevent scheduling errors, especially during daylight saving transition periods when offsets change. Use timezone-aware scheduling tools.
