About MAWSON
A fixed, year-round offset.

IANA zones · the technical identifiers
The zone that resolve to MAWSON.
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.
Where MAWSON is used

Other zones at UTC+05:00 right now.
These named zones share MAWSON's offset today. When daylight saving rules differ, they drift apart for part of the year.
Frequently asked questions
Common questions about MAWSON, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Does Mawson Time ever change for daylight saving?
- No. Mawson Time stays fixed at UTC+05:00 all year, so there are no daylight saving transitions to track.
- Where is Mawson Time actually used?
- It’s primarily associated with Antarctica/Mawson, the zone serving Mawson Station and surrounding operations on the continent.
- How many time zones are in the MAWSON region?
- Just one: Antarctica/Mawson. The region is represented by this single zone.
- Is there any DST coming up in Mawson Time?
- Currently, no future DST transitions are scheduled; the offset has been steady since at least 2021.
- What’s the current abbreviation for Mawson Time?
- It’s shown as +05, reflecting its constant five‑hour advance over UTC.
- How does constant UTC+05:00 help Antarctic operations?
- By never shifting for daylight saving, flight logs, data timestamps, and supply runs all stay on a consistent clock, reducing errors.
- Is Mawson Time used outside Antarctica?
- The official list only includes Antarctica; if other sites use UTC+05:00, they typically cite a different zone name.
