About WIT
A fixed, year-round offset.
Eastern Indonesia Time (WIT) keeps things straightforward across its single member zone, Jayapura, which sticks to UTC+09:00 all year round with no daylight saving confusion. Businesses and communities here enjoy the one-clock simplicity that makes scheduling and communication a breeze.
IANA zones · the technical identifiers
The zone that resolve to WIT.
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 WIT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why doesn't WIT observe daylight saving time?
- Indonesia lies near the equator, where there are minimal seasonal changes in daylight hours, so daylight saving time is unnecessary.
- What does having only one member zone mean for this timezone?
- It means that the entire region uses a single, consistent time zone. Whether you are in Jayapura or elsewhere in Eastern Indonesia, there is no need to adjust clocks DST-wise.
- How does WIT compare to other Indonesian time zones?
- Indonesia uses three different time zones, and WIT represents the most eastern one. The other two are Central Indonesia Time (WIB, UTC+07:00) and Western Indonesia Time (WIB, UTC+07:00), but WIT (UTC+09:00) aligns Jayapura with cities like Tokyo and Pyongyang rather than the rest of Indonesia’s time zones.
- Is WIT used outside of Indonesia?
- Technically yes, other time zones like Japan Standard Time (JST) and Korea Standard Time also use UTC+09:00, but WIT specifically refers to Eastern Indonesia Time and is only used in Indonesia’s Papua region.
- What are the benefits of being in the WIT time zone?
- Being aligned with major economies like South Korea and Japan can facilitate smoother business communication and coordination across Asia.
- How do I set my clock in Jayapura?
- Simply set your clock to UTC+09:00—no need for seasonal reset due to lack of DST.
- Has WIT’s UTC offset ever changed?
- The offset has been fixed at UTC+09:00 since May 2021, following a national review aimed at simplifying Indonesia’s timekeeping practices.
