A fixed, year-round offset.
Armenia Standard Time (AST) keeps clocks steady at UTC+04:00 year-round, with no daylight saving shifts. Whether you're coordinating with Yerevan or building across Armenia, the consistent offset simplifies scheduling and avoids the twice-yearly clock changes many other regions deal with.
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.
