Colombo, Sri Lanka keeps Asia/Colombo time. Every Vedic daily timing here, the Panchang, Rahu Kaal, Choghadiya and Muhurat, is built from Colombo's own sunrise and sunset, not a single all-India (IST) table, so it is specific to Colombo and shifts a little each day. Timings in Colombo follow its own local sunrise, not an Indian (IST) table. The live panel on each page is recalculated daily for Colombo.
The live panel shows today's day and night Choghadiya for Colombo, recalculated from local sunrise.
Amrit, Shubh, Labh and Char are favourable; Rog, Kaal and Udveg are avoided. Exact times depend on Colombo's sunrise.
