UTC+08:00

UTC+08:00 is an identifier for a time offset from UTC of +08:00. In ISO 8601, the associated time would be written as 2026-08-16T00:59:30+08:00. It is eight hours ahead of UTC, meaning that when the time in UTC is midnight (00:00), the time in areas using the time zone would be 08:00.

It is the most populous time zone in the world, as well as a possible candidate for ASEAN Common Time, mainly due to China's large population, with an estimated population of 1.4 billion people.

This time zone is used in all predominantly Chinese-speaking regions, giving international Chinese websites and TV channels the same time.

The time zone is known as Central Indonesian Time (Indonesian: Waktu Indonesia Tengah/WITA) in Indonesia, Australian Western Standard Time in Australia, and Irkutsk Time (Russian: Иркутское время) or MSK+5 (Russian: МСК+5) in Russia.
