December 2026 spans the lunar months of Kartika and Margashira. It opens on Krishna Ashtami, with the moon in Simha, and closes on Krishna Ashtami. The grid above shows every day's tithi and the exact time it ends — a tithi rarely fills a calendar day, so the end time is what tells you how much of it is left.

This month the full moon falls on Thursday, 24 December 2026, and the new moon on Tuesday, 8 December 2026.

No major festival falls in December 2026, but the monthly vratams below run as they always do — Ekadashi twice, Pradosham twice, and the rest on their own tithis.

Days are getting shorter through the month: the daylight period runs 10h 49m on the first and 10h 44m on the last. That matters more than it sounds, because rahu kalam, yamagandam and gulika kalam are each an eighth of the daylight period — so they shift and change length along with it. The timings on each day's page are computed for the city you have selected.
