About this tool
Convert time between Colombo and Washington, D.C. with live clocks and the current, daylight-saving-aware time difference.
See what time it is in Washington, D.C. when you know the time in Colombo — this converter shows both cities' clocks live and the exact current time difference between them, adjusted automatically for daylight saving. Colombo runs on the Asia/Colombo zone (IST) and Washington, D.C. on America/New_York (ET); the tool reads your browser's own time-zone data, so the offset is always right even across the days each city changes its clocks. Type any Colombo time to pin the matching Washington, D.C. time, or press swap to convert the other way. Nothing is uploaded.
