About SIT
A fixed, year-round offset.
Solomon Islands Time (SIT) sits at UTC+11 year-round for the Solomon Islands, stretching across Guadalcanal and neighboring archipelago without daylight saving. Since it never changes clocks, it offers a steady, predictable schedule that simplifies planning across South Pacific time zones.
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].
- Why doesn’t Solomon Islands use daylight saving?
- Being a tropical nation relatively close to the equator, daylight hours in the Solomon Islands don’t vary much through the year, making daylight saving unnecessary.
- What’s unique about Solomon Islands Time compared to nearby zones?
- SIT is fixed all year at UTC+11, unlike other parts of Oceania that switch between standard and daylight saving times, making it easier to keep consistent with distant teams.
- Which major places follow Solomon Islands Time?
- The representative city is Honiara on Guadalcanal, the capital of the Solomon Islands, which governs the official time used throughout the nation’s islands.
- How does SIT compare to neighboring New Zealand time?
- New Zealand alternates between UTC+12 and UTC+13 with daylight saving, so the gap between Honiara and Auckland can be either 1 or 2 hours depending on the time of year.
- Is Solomon Islands Time the same as any well-known business time zones?
- When it’s midday in Honiara (SIT), it’s around 7 AM in Tokyo and 8 AM in Sydney (non-DST), making early-morning planning windows useful for regional teams.
- How stable is this timezone historically?
- The Solomon Islands have recognized this fixed offset since 1912, providing over a century of consistent timekeeping for planning purposes.
- What’s the practical impact of no daylight saving in business?
- Without clock changes, timestamps and schedules stay predictable, so contracts, shipping logs, and meeting invites don’t need seasonal adjustments.
- Could Solomon Islands ever adopt daylight saving?
- It’s unlikely, given the minimal variation in daylight hours in this equatorial region and the simplicity that a fixed offset provides for international partners.
