|---|---|---|---|
| UTC | Coordinated Universal Time | UTC ±0 | Global reference standard (servers, logs, APIs) |

| 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
About IDT to SST Time Conversion
Converting time between Israel Daylight Time (IDT) and Samoa Standard Time (SST) bridges the eastern Mediterranean and the South Pacific. IDT is UTC+3, while SST is UTC-11 and stays constant year-round (American Samoa does not observe daylight saving time). That makes SST 14 hours behind IDT during the Israeli summer — from the Friday before the last Sunday in March to the last Sunday in October. Outside that window Israel is on IST (UTC+2) and the gap shrinks to 13 hours.
This converter uses the IANA timezone database (Asia/Jerusalem) to handle Israel's DST transitions automatically. Whether you're booking a call between Tel Aviv and Pago Pago during Israeli summer, or coordinating with Pacific-based teams from Israel, the tool removes the manual offset arithmetic.
Common Use Cases for IDT to SST Conversion
Business & Work
- Scheduling video calls between Tel Aviv or Jerusalem and American Samoa in summer
- Coordinating Israel–Pacific remote team handoffs and project work
- Planning conference calls that bridge Israeli and Samoan working hours
Personal & Travel
- Calling family in American Samoa from Israel
- Planning travel itineraries connecting through Israel to the Pacific
- Coordinating events with audiences across hemispheres

Frequently Asked Questions
What is the time difference between IDT and SST?
Israel Daylight Time (IDT) is UTC+3, while Samoa Standard Time (SST) is UTC-11. SST is 14 hours behind IDT. When it is 12:00 PM in Tel Aviv, it is 10:00 PM the previous day in Pago Pago.
When does this IDT to SST conversion apply?
It applies during Israeli summer, from the Friday before the last Sunday in March to the last Sunday in October. Outside that window Israel is on IST (UTC+2) and the gap drops to 13 hours. American Samoa stays on SST (UTC-11) year-round.
How does the time difference change throughout the year?
The gap is 14 hours during IDT (late March to late October) and 13 hours during Israeli IST (late October to late March). American Samoa never observes daylight saving, so any seasonal change comes from the Israeli side.
What are the best times for IDT–SST business calls?
A 14-hour gap with the date line in between leaves only a thin overlap. Late evening IDT (8:00–10:00 PM in Tel Aviv) maps to 6:00–8:00 AM the same day in Pago Pago — late on one side, early on the other.
Which countries and regions use SST?
Samoa Standard Time (UTC-11) is used in American Samoa and the uninhabited Midway Atoll. The independent state of Samoa is on UTC+13, on the opposite side of the international date line. Major American Samoa locations include Pago Pago, Tafuna, and Nu’uuli.
Which countries and regions use IDT?
Israel Daylight Time covers Israel during summer months. Major cities include Tel Aviv, Jerusalem, Haifa, Rishon LeZion, and Petah Tikva. The Palestinian Territories also follow Israel's DST rules.
Pro Tips
- • SST is 14 hours behind IDT — more than half a day, plus a date-line crossing, so always confirm the date.
- • American Samoa never observes daylight saving, so any seasonal shift comes from the Israeli side switching between IDT and IST.
- • Late evening IDT and early morning SST is the most workable overlap window for live calls.
- • Outside Israeli summer (late October to late March) Israel is on IST (UTC+2) and the gap drops to 13 hours.
- • Recurring meetings drift twice a year unless you re-pin them around the IDT/IST switch.
- • For one-off calls, double-check the IANA zones (Asia/Jerusalem, Pacific/Pago_Pago) in your calendar tool.
