Top 10 Most Common Time Zones

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

| 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 IDT to BRT Time Conversion
Converting between Israel Daylight Time (IDT) and Brasilia Time (BRT) connects Israel with Brazil during the warmer months. IDT is UTC+3 and BRT is UTC-3, putting Sao Paulo, Rio de Janeiro and Brasilia 6 hours behind Tel Aviv, Jerusalem and Haifa.
This converter uses the IANA timezone database for accurate calculations. IDT is observed from the Friday before the last Sunday in March to the last Sunday in October. Outside that window, Israel reverts to IST (UTC+2) and the gap to BRT becomes 5 hours.

Frequently Asked Questions
What is the time difference between IDT and BRT?
Israel Daylight Time (IDT) is UTC+3, and Brasilia Time (BRT) is UTC-3. BRT is 6 hours behind IDT. When it is 12:00 PM in Tel Aviv, it is 6:00 AM in Brasilia.
When does this IDT to BRT conversion apply?
IDT runs from the Friday before the last Sunday in March to the last Sunday in October. Outside that window, Israel reverts to IST (Israel Standard Time, UTC+2), and the gap to BRT shrinks to 5 hours.
How does the time difference change throughout the year?
During the Israeli summer the offset is 6 hours; during the winter it shrinks to 5 hours when Israel is on IST. Brazil ended DST in 2019, so the Brazilian side never shifts.
What are the best times for IDT-BRT business calls?
A 6-hour gap leaves a narrow shared window. A late afternoon in Tel Aviv (4:00 to 6:00 PM IDT) maps to a Brazilian morning (10:00 AM to 12:00 PM BRT). For end-of-day handovers, schedule around 8:00 PM IDT, which is 2:00 PM BRT.
Which countries/regions use BRT timezone?
BRT is observed across most of Brazil, including Brasilia, Sao Paulo, Rio de Janeiro, Belo Horizonte and Salvador. A few western Brazilian states use AMT (UTC-4) instead.
Which countries/regions use IDT timezone?
IDT covers the State of Israel during the summer months. Major cities include Tel Aviv, Jerusalem, Haifa, Beersheba and Eilat.
Pro Tips
- • BRT is 6 hours behind IDT — subtract 6 hours from a Tel Aviv time to get the Brasilia time.
- • When Israel switches back to IST in late October, the offset shrinks to 5 hours until late March.
- • Brazil does not observe DST, so any seasonal change comes from the Israeli side.
- • Use IANA identifiers (Asia/Jerusalem and America/Sao_Paulo) in calendars to handle the IDT-IST transitions automatically.
- • The Israeli weekend is Friday-Saturday — different from the Brazilian Saturday-Sunday — so plan handovers accordingly.
- • Israeli late afternoon to early evening pairs cleanly with Brazilian late morning to early afternoon.
