Anadyr Standard Time
Anadyr Standard Time (AST) covers the far eastern corner of Russia, including the Chukotka region around the city of Anadyr, and sits at a steady UTC+12:00 year-round with no daylight saving changes, making scheduling across this zone more predictable for anyone collaborating with teams or travelers in one of Russia’s most remote timekeeping outposts.

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.

- Is Anadyr Standard Time always UTC+12:00?
- Yes. Unlike many Russian zones that used to spring forward or fall back, Anadyr Standard Time has remained fixed at UTC+12:00 for more than a decade, so there are no daylight saving surprises.
- How many time zones use Anadyr Standard Time?
- Only one: Anadyr, which covers the whole Chukotka region.
- Where exactly is Anadyr Standard Time used?
- It applies primarily to the Chukotka region around the city of Anadyr in the Russian Far East, a sparsely populated area near the border with Alaska.
- Do clocks ever change for daylight saving in this zone?
- No. This region does not observe daylight saving time, so the local time stays the same throughout the year.
- What does the abbreviation “+12” mean on clocks and schedules?
- It’s a short way to show the offset from UTC. When it’s midnight in UTC, it’s already noon the same calendar day in Anadyr.
- Why is Anadyr Standard Time considered remote but interesting?
- It governs one of the few populated areas just west of the International Date Line, meaning you can be among the first places on Earth to start a new calendar day.
- When did Anadyr last change its time rules?
- Since 2011 Anadyr has been fixed at UTC+12, with no daylight saving transitions scheduled.
- Is there any upcoming time change expected for Anadyr?
- No future transitions are recorded, and the zone is expected to remain on the same offset unless Russian time policy changes.
- How does Anadyr Standard Time compare to nearby zones?
- It shares UTC+12:00 with Kamchatka in Russia and with Pacific countries such as Fiji, Tuvalu and the Marshall Islands. New Zealand is also on UTC+12:00 in its winter.
