AST
Azerbaijan Standard Time
Azerbaijan Standard Time (AST) keeps Azerbaijan firmly set at UTC+04:00 with no daylight saving changes, making it one of the simpler time regions to track for anyone coordinating with Baku or working across this South Caucasus hub—just one stable offset year-round means fewer scheduling surprises and a reliable anchor for logistics, remotes teams, and trading partners.

About AST
A fixed, year-round offset.
Azerbaijan Standard Time (AST) keeps Azerbaijan firmly set at UTC+04:00 with no daylight saving changes, making it one of the simpler time regions to track for anyone coordinating with Baku or working across this South Caucasus hub—just one stable offset year-round means fewer scheduling surprises and a reliable anchor for logistics, remotes teams, and trading partners.
IANA zones · the technical identifiers
The zone that resolve to AST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

- Does Azerbaijan observe daylight saving time?
- No, Azerbaijan discontinued daylight saving observance after 2016 and has remained on a fixed UTC+04:00 offset, making scheduling more predictable.
- What is the time difference between Baku and London?

- What is the time difference between Baku and New York?
- Baku is typically 8–9 hours ahead of New York, depending on whether the U.S. is observing daylight saving time.
- Is there more than one time zone in Azerbaijan?
- No, the entire country follows a single time zone, Asia/Baku, which aligns with Azerbaijan Standard Time at UTC+04:00.
- Why does Azerbaijan no longer observe DST?
- In 2016, Azerbaijan decided to abolish daylight saving time to simplify timekeeping, improve energy efficiency, and align better with regional partners.
- How does the fixed offset benefit international collaboration?
- A stable UTC+04:00 offset reduces confusion, avoids biannual schedule shifts, and simplifies coordination with global teams or supply chains.
- Which countries share the same UTC+04:00 offset?
- Regions like Georgia, Armenia, and parts of Russia (e.g., Samara) share this offset, though daylight rules may differ.
- What is the best time to schedule meetings with Baku-based teams?
