Time in Indonesia
The Indonesian archipelago geographically stretches across four time zones from UTC+07:00 in Aceh to UTC+09:00 in Papua. Therefore, the Indonesian government recognizes three time zones in its territory:
- Western Indonesia Time (WIB) — seven hours ahead (UTC+07:00) of the Coordinated Universal Time (UTC or GMT)
- Central Indonesia Time (WITA) — eight hours ahead (UTC+08:00) of UTC; and
- Eastern Indonesia Time (WIT) — nine hours ahead (UTC+09:00) of UTC
The boundary between the Western and Central time zones was established as a line running north between Java and Bali through the provincial boundaries of West and Central Kalimantan. The border between the Central and Eastern time zones runs north from the eastern tip of Indonesian Timor to the eastern tip of Sulawesi.
Daylight saving time is no longer observed anywhere in Indonesia.
