MAWSON

Mawson Time

Mawson Time covers the research outpost at Mawson Station in Antarctica, clocking in at a steady UTC+05:00 year-round with no daylight saving adjustments. For expedition teams and remote collaborators, the unchanging offset simplifies mission planning across the long polar day and night.

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.

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].

Why doesn't Mawson observe daylight saving time?
In polar regions, daylight saving offers little benefit; the sun either stays above or below the horizon for months. Mawson chose a fixed UTC+05:00 since 2009 to provide consistent research schedules.
Is Mawson Time the same throughout the year?
Yes. There have been no changes to Mawson's UTC+05:00 offset since its adoption on 18 October 2009, making every day at the station share the same local time.
What is the standard abbreviation for Mawson Time?
The region is abbreviated as +05, reflecting its fixed offset without daylight saving variations.
Which countries use Mawson Time?
Only one country has a zone using Mawson Time: Antarctica's Mawson Station operated by Australia.
When was Mawson Time established as UTC+05:00?
Mawson Station adopted its current UTC+05:00 offset on 18 October 2009, balancing communications with Australian support teams and daylight cycles.
