Time in Colombo, Sri Lanka

Time zone: +0530 (UTC/GMT +05:30) — Asia/Colombo

Colombo runs on +0530. That places it 5 hours 30 minutes ahead of UTC (UTC+05:30); in a calendar, server config or booking form, select Asia/Colombo.

Colombo does not change its clocks. The same UTC+05:30 offset holds in January and July, which makes it a stable anchor for recurring calls.

With a population near 648,034, Colombo comes in 1st of the 11 Sri Lanka cities we list.

Current gap between Colombo and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

No shared working window exists with New York, Los Angeles or Sao Paulo, so those calls have to sit outside somebody's normal hours.

These Sri Lanka cities also use Asia/Colombo, so their clocks read identically to Colombo at every moment of the year.
