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 PST and EDT?
Pacific Standard Time (PST) is UTC-8, while Eastern Daylight Time (EDT) is UTC-4. This means EDT is 3 hours ahead of PST. When it's 9:00 AM in Los Angeles (PST), it's 12:00 PM (noon) in New York (EDT).
How does the PST to EDT offset compare to other timezone pairs?
The 3-hour difference between PST and EDT is standard for coast-to-coast US coordination. This is the same offset between CST and EST, or between PDT and EDT. PST to EDT represents winter time on the West Coast and daylight time on the East Coast.
When does the time difference change between PST and EDT?
The time difference fluctuates during daylight saving transitions. From November to March, PST is 3 hours behind EST. From March to November, PST is 3 hours behind EDT. During brief transition periods (usually 1-2 weeks in March and November), the offset may be 2 or 4 hours.
What is the difference between PST/PDT and EST/EDT?
PST (Pacific Standard Time, UTC-8) and PDT (Pacific Daylight Time, UTC-7) are used on the West Coast. EST (Eastern Standard Time, UTC-5) and EDT (Eastern Daylight Time, UTC-4) are used on the East Coast. The West Coast is always 3 hours behind the East Coast during corresponding seasons.
What are the best times to schedule meetings between West Coast and East Coast?
The 3-hour time difference allows for good business hour overlap. Morning on the West Coast (9-11 AM PST) overlaps with late morning/early afternoon on the East Coast (12-2 PM EDT). This is typically the best window for meetings. Afternoon on the West Coast (2-4 PM PST) works well for early morning East Coast (5-7 AM EDT) calls.
Why is coast-to-coast coordination important for US businesses?
The US West and East Coasts represent major business hubs. San Francisco/Silicon Valley (tech), Los Angeles (entertainment, aerospace), Seattle (tech) on the West, and New York (finance), Boston (biotech, finance), Washington DC (government, consulting) on the East require frequent coordination. The 3-hour difference makes same-day meetings feasible with proper scheduling.
Pro Tips
- • Remember the 3-hour rule: EST is always 3 hours ahead of PST. Add 3 hours to PST to get EDT during daylight saving season.
- • Peak overlap hours are 9 AM-12 PM PST (12 PM-3 PM EDT). Schedule important meetings in this window for maximum availability.
- • Early morning East Coast (6-7 AM EDT) corresponds to late evening West Coast (3-4 PM PST) - useful for urgent matters before the workday ends.
- • Avoid scheduling meetings before 8 AM PST or after 6 PM EDT. These times fall outside standard business hours on the opposite coast.
- • During daylight saving transitions (March and November), the difference becomes 2 or 4 hours for 1-2 weeks. Mark your calendar!
- • Use full timezone names (PST/EDT) in calendar invites instead of abbreviations, as they clearly indicate standard vs. daylight time.
