Kshaya Tithi and Vriddhi Tithi: Every Case, 2026–27

A Hindu calendar day takes its tithi from the moment the Sun rises. That reading is the udaya tithi, and when someone says a vrat falls “by udaya tithi” (udaya tithi ke hisab se) they mean the day whose sunrise the tithi is current at. Most tithis last close to a day, so most hold exactly one sunrise and name exactly one day. Two kinds do not. A kshaya tithi starts after one sunrise and is over before the next, so no day carries its name. A vriddhi tithi is already running at one sunrise and is still running at the next, so two days in a row carry the same name.

Reading the sunrise tithi at New Delhi for all 730 days of 2026 and 2027 in the site’s computed panchang, 34 tithis were kshaya (17 in 2026, 17 in 2027) and 23 were vriddhi (11 and 12). Below is every case from November 2026 to the end of 2027, what it did to the festival table, and how near each one came to going the other way.

One Case Worked Through: Dev Uthani Ekadashi 2026

On Friday 20 November 2026 the Sun rises at New Delhi with Shukla Dashami still running. The Shukla Ekadashi begins 29 minutes later and lasts 23 h 16 min, which is less than the gap to the next sunrise; it closes sixteen minutes before the Sun comes up on Saturday, by which time Shukla Dwadashi has taken over. The daily panchang therefore lists Shukla Dashami on the 20th and Shukla Dwadashi on the 21st, and Ekadashi appears on neither line. The festival table still has to put Dev Uthani Ekadashi somewhere, and it puts it on Friday 20 November, the day the Ekadashi opens. Why the fast can honestly be kept on either day, and what a Vaishnava calendar does instead, is the subject of the Dev Uthani Ekadashi 2026 page.

Every Kshaya and Vriddhi Tithi, November 2026 to December 2027

For a kshaya tithi the dates are the two sunrises it falls between; for a vriddhi tithi, the two sunrises it holds. The margin is how many minutes separate the tithi’s nearer edge from a New Delhi sunrise: the smaller it is, the closer the case came to being an ordinary one-sunrise tithi.

That is twenty kshaya and fourteen vriddhi tithis in fourteen months. The lengths sort them cleanly: every kshaya tithi in the list is shorter than twenty-four hours, the longest being the Shukla Ekadashi of 20 November at 23 h 16 min, and every vriddhi tithi is longer, the shortest being the Krishna Dwitiya of 17 September at 24 h 52 min. Length alone does not decide it, though. A tithi of twenty-three hours still holds a sunrise if it happens to begin a little before one; what makes it kshaya is that both of its edges fall inside the same night-and-day gap.

Why There Are More Kshaya Than Vriddhi

The imbalance is built in. A lunar month has thirty tithis but only twenty-nine or thirty sunrises, so over a long run the tithis outnumber the days that can be named after them. Every tithi that names no day is a kshaya; every tithi that names two is a vriddhi. Across the 730 sunrises of 2026–27, 741 different tithis ran, and the surplus, 11, is exactly the 34 kshaya minus the 23 vriddhi. How long tithis and months actually run is measured on how many days are in a lunar month.

No tithi is kshaya by nature. Over the two years, 19 of the thirty tithi names were skipped at least once and none more than four times, a spread with no pattern a reader could plan around. Which tithi goes missing depends on where the Moon is in its orbit and on the hour the tithi happens to begin, both of which shift from month to month. The per-tithi pages under tithi in the panchang list the skipped and repeated days for each name.

What a Kshaya Tithi Does to a Festival

Of the festivals the site tabulates, four land on a kshaya tithi in this stretch: Dev Uthani (Prabodhini) Ekadashi on Friday 20 November 2026, Sakat Chauth (Sankashti Chaturthi) on Monday 25 January 2027, Hariyali Teej on Wednesday 4 August 2027 and the first day of Sharad Navratri on Thursday 30 September 2027. In all four the table gives the festival to the day on which the tithi opens. That is a convention, and almanacs that apply another rule can land on the next day instead; the Ghatasthapana question this raises for Navratri is worked through on Navratri 2027, and the moonrise reading that keeps Sakat Chauth on its day is on the Sankashti Chaturthi 2027 list.

A festival that is tested at some other moment of the day than sunrise can sidestep the problem altogether. A kshaya tithi still has a stretch of daylight or evening in it, so a festival read at noon, at pradosh or at midnight can find the tithi running at that moment on one of the two days even though it holds no sunrise.

What a Vriddhi Tithi Does

A vriddhi tithi is the opposite problem: two days have an equal claim by the sunrise test. The festival table flags only one such row in the stretch, Durga Ashtami on Thursday 7 October 2027, and dates it to the first of the two days. The Shukla Ashtami holds the sunrise of both 7 October and 8 October, so a reader who finds a calendar printing the second day is looking at a different rule, not a mistake. The other vriddhi cases in the list touch no tabulated festival, but they matter for any vrat kept by tithi: a monthly fast on, say, a Krishna Chaturthi that runs across two sunrises needs a rule for which of the two days to keep, and the rule belongs to the family’s calendar.

Why the List Can Differ Between Cities

The tithi itself begins and ends at the same instant everywhere. Sunrise does not: across India it moves by over an hour between the far east and the far west on the same date. The Shukla Saptami of 10 June 2027 closes eight minutes before the New Delhi sunrise, so in a city where the Sun comes up more than eight minutes earlier it is still running at sunrise, and there it is not kshaya at all. The Krishna Panchami of 25 April 2027 works the other way: it opens only four minutes before the New Delhi sunrise, so a city whose sunrise comes earlier still has the previous tithi at dawn and sees one sunrise in it, not two. Of the 34 cases above, seven sit within fifteen minutes of a New Delhi sunrise: the Krishna Chaturthi of 27 November 2026, the Purnima of 23 December 2026, the Shukla Tritiya of 10 January 2027, the Krishna Panchami of 25 April 2027, the Shukla Saptami of 10 June 2027, the Krishna Dwitiya of 17 September 2027 and the Shukla Ashtami of 7 October 2027. Those are the ones on which almanacs printed for other cities are most likely to disagree with this table, and Durga Ashtami 2027 is among them. The cases with margins of an hour or more will read the same almost anywhere in the country.

This page does not grade a kshaya or a vriddhi tithi as good or bad for anything. It reports where they fall. To see how a missing or doubled tithi moves a birthday kept by the Hindu calendar, use the tithi birthday table; for how the muhurat rules group tithis, see the Rikta, Nanda, Bhadra, Jaya and Purna groups.

In Brief

• Udaya tithi: the tithi current at sunrise, which names the day
• Kshaya tithi: opens after one sunrise and closes before the next; 34 in 2026–27 at New Delhi
• Vriddhi tithi: holds two sunrises; 23 in 2026–27
• Festivals touched, Nov 2026 to Dec 2027: four on kshaya tithis and one on a vriddhi tithi
• City differences: likeliest on the seven cases with a margin under fifteen minutes
