History in Sri Lanka

On 15 April 2006, Sri Lanka Time went back to match Indian Standard Time calculated from the Allahabad Observatory in India 82.5° longitude east of Greenwich, the calculation place for GMT. This time zone is used fully by Sri Lanka.

Since 1880, the time zone in Sri Lanka (also known as Ceylon up to 1972) has changed from UTC+05:30 to UTC+06:30.[1][2]
