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 |

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 PST to EET Time Conversion
Converting time between Pacific Standard Time (PST) and Eastern European Time (EET) is essential for coordinating between the Pacific Coast and Eastern Europe. PST is UTC-8 (observed during winter, November to March), while EET is UTC+2 (observed during winter, same months). EET is 10 hours ahead of PST.
This conversion is important for international businesses coordinating between Pacific region cities (Los Angeles, San Francisco, Seattle) and Eastern European cities (Athens, Cairo, Helsinki). The large 10-hour offset during winter decreases to 9 hours during summer when PST transitions to PDT and/or EET transitions to EEST. Both regions observe daylight saving time on different dates, creating seasonal variations in the time difference. Tech companies, finance firms, research institutions, and international organizations manage this significant time gap through careful scheduling and asynchronous communication. Understanding the seasonal transitions is crucial for managing recurring meetings and business operations.
Common Use Cases for PST to EET Conversion
Business & Work
- Scheduling calls between Pacific Coast offices and Eastern European headquarters
- Coordinating international tech development teams across regions
- Managing global finance operations with offices in both regions
- Planning international conferences and meetings with both regions
Personal & Travel
- Coordinating with family and friends in Eastern Europe
- Planning travel between Pacific Coast and Eastern European destinations
- Scheduling virtual meetings with Eastern Europe-based relatives
- Arranging online collaboration with Eastern Europe-based colleagues

Quick Reference: PST to EET
Remember: EET is 10 hours ahead of PST (November-March). When PDT and/or EEST are active (summer months), the difference reduces to 9 or 8 hours. Always verify which period applies when scheduling.
Frequently Asked Questions
What is the time difference between PST and EET?
Pacific Standard Time (PST) is UTC-8, while Eastern European Time (EET) is UTC+2. This means EET is 10 hours ahead of PST. When you have 12:00 PM in Los Angeles (PST), it's 10:00 PM the same day in Athens (EET).
How does the time difference change when PST transitions to PDT?
When PST transitions to PDT (Pacific Daylight Time, UTC-7) during summer, the difference with EET decreases to 9 hours. During winter (October-March): PST is 10 hours behind EET. During summer (March-October): PDT is 9 hours behind EET. This seasonal change requires adjustment for recurring meetings.
Does Eastern Europe observe daylight saving time?
Yes, Eastern Europe transitions from EET (UTC+2, winter) to EEST (UTC+3, summer) on the last Sunday of March and back on the last Sunday of October. This means the time difference with PST/PDT varies: 10 hours (PST-EET), 9 hours (PDT-EET), 9 hours (PST-EEST), and 8 hours (PDT-EEST).
What are the best times to schedule calls between Pacific Coast and Eastern Europe?
The large 9-10 hour difference limits overlap. Late evening in Pacific (8-10 PM PST/PDT) corresponds to morning next day in Eastern Europe (6-8 AM EET/EEST). Early morning in Pacific (6-8 AM PST/PDT) corresponds to evening in Eastern Europe (4-6 PM EET/EEST). Plan important meetings in these narrow windows.
Why is the 9-10 hour offset challenging for business coordination?
The large time difference means minimal business hour overlap. While morning meetings in one region occur during evening in the other, finding times suitable for both parties requires careful planning. Asynchronous communication via email and recorded messages often works better than real-time calls.
Which industries coordinate across Pacific and Eastern European timezones?
Tech companies, finance firms, research institutions, and international organizations operate across these regions. Software development teams, IT services, e-commerce platforms, and consulting firms manage the time difference through shift work, asynchronous collaboration, and strategic meeting scheduling at optimal times.
Pro Tips
- • The 9-10 hour time difference is substantial. Plan major business communications for evening Pacific time (8-10 PM PST/PDT), which corresponds to morning Eastern Europe time (6-8 AM EET/EEST next day).
- • Winter brings a 10-hour offset (PST-EET), while summer brings 9 hours (PDT-EEST). During transition periods, verify which timezone offset applies to avoid confusion.
- • Early morning Pacific time (6-8 AM PST/PDT) aligns with evening Eastern Europe (4-6 PM EET/EEST). This window works for time-sensitive business matters requiring real-time discussion.
- • Both regions transition on different dates: Pacific (second Sunday in March/first Sunday in November) and Eastern Europe (last Sunday in March/October). Track both calendars to anticipate offset changes.
- • Asynchronous communication is more efficient than real-time calls. Use video messages, detailed emails, and shared documents for daily collaboration and updates.
- • When scheduling recurring meetings, choose times that work year-round to minimize adjustment needs. The evening Pacific / morning Eastern Europe window is most reliable for both regions.
