What China and IST mean

China time

China keeps one official time for the whole country, China Standard Time (UTC+8), with no daylight saving time. tzdata lists a separate zone at UTC+6, Asia/Urumqi, for the time many people use in Xinjiang; this page uses the official time.

India Standard Time

IST here is India Standard Time, UTC+5:30, used in all of India all year: no daylight saving time and a single zone for the whole country.

IST can also mean Israel Standard Time (UTC+2, Israel) or Irish Standard Time (UTC+1, Ireland, in summer). This page uses India Standard Time, the meaning people searching for this conversion have in mind. For another one, type the city into the time zone converter.

Questions

How many hours behind China is IST?
IST is 2 hours 30 minutes behind China time all year. Neither side changes its clocks.
When is IST on a different date from China?
From midnight until 2:30 AM China, IST is still on the previous calendar day. So a time early in the China day needs the previous date on the IST side.
Why is the difference not a whole number of hours?
India is on UTC+5:30, a half-hour offset, so every whole hour on one side falls at half past the hour on the other.
