Ekadashi dates in the USA

Ekadashi is dated by the tithi current at local sunrise, so the American date can differ by one day from India's. The next three, computed independently for each location:

Every column is computed for that location’s own sunrise (Udaya Tithi, Smarta convention). When New York and Delhi disagree, both are correct for their own sunrise — this is a property of the lunar calendar, not an error.

Case breakdown: why Mokshada falls on 2026-12-19 in San Francisco but 2026-12-20 in India

Take the mismatched row above. The tithi itself is one physical event — it begins at 22:09 IST on 19 Dec and ends at 20:15 IST on 20 Dec, the same universal instant worldwide. Delhi’s sunrise on 2026-12-20 falls inside that window, so India observes it on 2026-12-20. In San Francisco the very same beginning instant reads as 08:39 local time — before that day’s local sunrise, so the tithi is already running when the Sun rises and the city keeps it on 2026-12-19, one day earlier than India.

Neither reading is an error: the Udaya Tithi rule anchors the date to whichever sunrise finds the tithi running, and sunrise differs by hours across longitudes.

Methodology and reference

All timings on this page are computed astronomically for the respective local coordinates — solar and lunar sidereal positions, the Lahiri (Chitrapaksha) ayanamsa and sunrise-anchored window divisions — and regression-checked against the Government of India publication Rashtriya Panchang (Positional Astronomy Centre, India Meteorological Department, Kolkata). Data verified against the Positional Astronomy Centre, IMD (Government of India) publications on every site update; the computation method is described on the about page.
