Ekadashi Dates in August and September 2026 — With Exact Tithi Timings

Ekadashi is the eleventh tithi of each lunar fortnight, observed as a fast twice in every lunar month — once in the waxing (Shukla) and once in the waning (Krishna) paksha. The confusion every month is the same: the tithi often begins on one calendar day and the fast falls on the next. Here are the exact windows, so you can see why.

The four Ekadashis, with exact tithi windows (IST, New Delhi)

Why the fast day is not the day the tithi starts

Look at 9 August: the Ekadashi tithi began the previous afternoon (8 August, 1:59 PM) — yet the fast is on the 9th. The deciding question in the classical nirnaya is: which day does Ekadashi prevail at sunrise? On 9 August, sunrise in Delhi is 5:47 AM and the tithi runs until 11:05 AM — so the 9th is the fast day, not the 8th. Our engine applies this sunrise-prevalence test (following the rules it carries from the Dharmasindhu and Nirnayasindhu nirnaya tradition) to every date above, for the Smarta observance. In these two months the Smarta and Vaishnava dates happen to agree on all four fasts.

Check it yourself

If you open the panchang for 8 August 2026, then you will see Ekadashi begin mid-afternoon — and at sunrise that morning the tithi is still Dashami. That is exactly why a calendar that lists Ekadashi on the 8th would send you to fast a day early. The tithi at sunrise, not the tithi's start, names the day.

Where we disagree with most listing sites

Most date lists publish a bare date with no timings and no rule — and when lists disagree, you have no way to judge who is right. We publish the tithi windows and the rule, so you can verify the date rather than trust it. That is the same principle our astrologers apply in consultations: verifiable first, then advice.
