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) |

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 PDT Time Conversion
Converting time between Eastern European Time (EET) and Pacific Daylight Time (PDT) is essential for coordinating between Eastern Europe and the US West Coast during summer months. EET is UTC+2 (during winter) and UTC+3 during daylight saving time (EEST), while PDT is UTC-7 (observed during daylight saving time, March to November). When both regions are observing daylight saving time, EET (as EEST, UTC+3) is 10 hours ahead of PDT. During the brief winter periods, the offset can be different.
This conversion is crucial for Eastern European companies coordinating with US West Coast offices in California during the summer months. Major tech hubs in Silicon Valley, Seattle, and Portland frequently partner with development teams from Greece, Romania, Bulgaria, and other Eastern European nations. Software development teams, outsourcing firms, and enterprises bridging Eastern Europe and US West Coast operations rely on accurate time conversions. PDT is specifically observed from the second Sunday in March to the first Sunday in November, requiring attention to transition dates for scheduling.
Common Use Cases for EET to PDT Conversion
Business & Work
- Scheduling calls between Eastern European offices and Silicon Valley tech companies
- Coordinating software development teams across Eastern Europe and US West Coast
- Managing business process outsourcing operations with California-based clients
- Planning conference calls for tech companies with presence in both regions during summer
Personal & Travel
- Coordinating with family and friends in the US West Coast region
- Planning travel between Eastern Europe and California destinations
- Scheduling virtual meetings with West Coast relatives or business partners
- Arranging online collaboration with California-based colleagues during daylight saving period

Quick Reference: EET to PDT
Remember: When both regions are observing daylight saving time (EEST and PDT), EET is 10 hours ahead of PDT. Both regions transition to daylight saving on different dates - Europe changes to EEST on the last Sunday of March, while the US West Coast transitions PDT on the second Sunday of March (earlier).
Frequently Asked Questions
What is the time difference between EET and PDT?
Eastern European Time (EET) is UTC+2 (winter) or UTC+3 (summer with EEST), while Pacific Daylight Time (PDT) is UTC-7. During winter months when EET is UTC+2, EET is 9 hours ahead of PDT. During summer months when EEST is UTC+3, EET is 10 hours ahead of PDT (when both are observing daylight saving time).
How does the EET to PDT offset differ from other US timezones?
PDT is 3 hours behind EDT (Eastern Daylight Time) and 1 hour ahead of PST (Pacific Standard Time). Since EET is 9 hours ahead of PDT during summer months and 10 hours ahead when EEST is active, it's much further offset than Eastern timezones. PDT represents the West Coast during daylight saving time (March-November).
When is PDT observed and what is the time difference during winter?
PDT (UTC-7) is observed from the second Sunday in March to the first Sunday in November. During winter (November-March), the US West Coast observes PST (UTC-8), making the offset 10 hours ahead from EET instead of 9 hours. Europe changes to EEST on the last Sunday of March, creating a brief period where both regions are in daylight saving time.
When is the best time for video calls between Eastern Europe and US West Coast?
Business hour overlap is limited due to the 9-10 hour difference. Early morning in Eastern Europe (7-9 AM EET) overlaps with late evening in California (10 PM-12 AM PDT). Evening in Eastern Europe (6-8 PM EET/EEST) overlaps with early morning in California (9-11 AM PDT). These narrow windows require careful scheduling.
Why do companies coordinate between Eastern Europe and US West Coast?
Eastern European countries like Greece, Romania, and Bulgaria have significant tech talent and outsourcing capabilities. The US West Coast, particularly Silicon Valley, has major tech companies seeking development teams. The 9-10 hour offset between regions requires split-shift operations or asynchronous communication for effective collaboration on projects.
How do daylight saving transitions affect EET to PDT coordination?
Europe transitions to EEST on the last Sunday of March, while the US transitions PDT on the second Sunday of March (earlier). Europe transitions back to EET on the last Sunday of October, while the US transitions back to PST on the first Sunday of November (later). During these transition weeks, the offset can be 9, 10, or 11 hours depending on which region has switched.
Pro Tips
- • EET transitions to EEST on the last Sunday of March, while PDT starts on the second Sunday of March. Be aware that for a few weeks in March, the difference might vary from the standard 9 hours.
- • The 9-10 hour offset is significant - a 9 AM EET meeting is 12 AM or 1 AM PDT. Asynchronous communication via email, Slack, or recorded videos is often more practical than live calls.
- • For synchronous meetings, schedule Eastern Europe morning (7-9 AM EET) for California late evening (10 PM-12 AM PDT), or Eastern Europe evening (6-8 PM EET) for California early morning (9-11 AM PDT).
- • PDT is observed from the second Sunday in March to the first Sunday in November. Mark your calendar for transitions, as the offset changes when either region switches to/from daylight saving time.
- • Use the 8-10 AM PDT window (5 PM-7 PM EET) for urgent Europe-California discussions when both teams can briefly connect during extended work hours.
- • Document all meeting times in both EET and PDT to prevent scheduling errors, especially during daylight saving transition periods when offsets change. Consider using timezone-aware scheduling tools.
