India Standard Time Zone - IST

India Standard Time is five and a half hours ahead of the Coordinated Universal Time standard, written as an offset of UTC + 5:30. That means to find the standard time in the zone you must add five and a half hours from Coordinated Universal Time.

India Standard Time is considered a nonstandard time zone because it does not have an hourly incremental difference like most other zones. Instead, there's an additional 30 minute time difference between this zone and standard time.

Territories observing the time zone are primarily in southern Asia. It runs through the countries of India and Sri Lanka. Those in the time zone also refer to it as Indian or India Time (IT) and Indian Standard Time (IST).

India and Sri Lanka remain on India Standard Time all year long and do not make any changes for Daylight Saving.
