The Indonesian archipelago geographically stretches across four time zones from UTC+7 in Banda Aceh to UTC+9 in Western Papua. However, The Indonesian government only recognizes three time zones in its territory: Indonesia Western Time—seven hours in advance (UTC+7) of Greenwich Mean Time (GMT), Indonesia Central Time— eight hours ahead (UTC+8) of GMT, and Indonesia Eastern Time—nine hours ahead (UTC+9) of GMT. The boundary between the western and central time zones established is a line running north between Java and Bali through the center of Kalimantan. The border between central and eastern time zones runs north from the eastern tip of Timor to the eastern tip of Sulawesi.

Daylight saving time is never observed in Indonesia due to its tropical location, resulting in each area using their respective time zone all year long.
