SIT
Solomon Islands Time
Solomon Islands Time (SIT, UTC+11:00) is used year-round across the Solomon Islands, keeping a steady clock that never shifts for daylight saving—ideal for simpler planning across the scattered Pacific island chain.

About SIT
A fixed, year-round offset.
Solomon Islands Time (SIT, UTC+11:00) is used year-round across the Solomon Islands, keeping a steady clock that never shifts for daylight saving—ideal for simpler planning across the scattered Pacific island chain.
IANA zones · the technical identifiers
The zone that resolve to SIT.
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 SIT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Does Solomon Islands Time ever change for daylight saving?
- No. Solomon Islands Time stays at UTC+11:00 all year, so clocks never move forward or backward.
- Which places use SIT?
- Mainly the Solomon Islands, represented by Pacific/Guadalcanal, including locations like Honiara and other islands in the archipelago.
- How does SIT compare to its neighbours?
- Solomon Islands Time aligns with parts of Russia, Vanuatu, and Fiji at UTC+11:00, but unlike some Pacific zones, it doesn’t switch for daylight saving.
- Is there a seasonal clock change risk when working with SIT?
- No. Because there’s no daylight saving, meeting times booked in SIT stay consistent throughout the year.
- Why doesn’t SIT observe daylight saving?
- The Solomon Islands are near the equator, where daylight hours change very little, so there’s little benefit from shifting clocks.
- When was SIT last adjusted?
- There is no scheduled DST transition; the region has been stable at UTC+11:00, with recent offsets confirmed as unchanged since 2021.
- Is SIT the same as Australian Eastern Time?
- They can overlap when Australia isn’t on daylight saving (both UTC+11:00), but Australian clocks move to UTC+11:00 only during part of the year, while SIT stays fixed at +11.
- Is SIT used by any other countries?
- Officially, SIT mainly applies to the Solomon Islands; nearby countries at UTC+11:00 often use their own named zones.
