Important days in April 2028
How the dates are chosen
Every date on this page is calculated from the sky for the chosen city: the Moon’s and Sun’s sidereal positions (Lahiri ayanamsa) give the tithi, and the city’s sunrise decides which civil day it belongs to. Nothing is copied from a printed calendar, so a date can differ by a day from a calendar made for another city or by another rule; the tithi’s start and end are given so you can see why.
Ekadashi
Ekadashi is the eleventh tithi of each fortnight. The fast is kept on the day whose sunrise falls in the tithi. Two traditions can differ by a day: in the Smarta reckoning that day stands, and in the Vaishnava reckoning the fast moves to the next day when Dashami was still running at arunodaya (about an hour and a half before sunrise), or when the Dwadashi that follows holds two sunrises. Where the two differ, both days are shown. Each Ekadashi carries a name from its month and fortnight; an adhika (extra) month has Padmini and Parama.
Purnima
The Purnima date is the day whose sunrise falls in the full-moon tithi. When the tithi begins in the morning of the day before and still runs at noon, the fast (Purnima vrat, Satyanarayan puja) is kept that earlier day; both days are shown then.
Amavasya
The Amavasya date is the day whose sunrise falls in the new-moon tithi; it is named by the purnimanta month, as printed calendars name it. When the tithi began the morning before, that evening is the Darsha, the Moon’s unseen night, and is noted.
Pradosh
Pradosh is kept on the Trayodashi of each fortnight, on the day whose evening (sunset to about two and a half hours after it) the tithi covers most. It takes the weekday’s name: Soma Pradosh on a Monday, Shani Pradosh on a Saturday, and so on.
Sankranti
A Sankranti is the moment the Sun enters a sidereal sign (Lahiri ayanamsa). The day is the civil day of that moment at the place. Makar Sankranti has its own page with the punya kaal; the other eleven mark the solar months.
The seventeen festivals come from their own pages, each with its rule and muhurat. These dates are for guidance; they decide nothing for you, and nothing here is a remedy.

Questions people ask
When is the next Ekadashi?
The list above names the next Ekadashi for the chosen city with the day the tithi begins and ends. Where the Smarta and Vaishnava days differ, both are given.
Why are there two dates for some Ekadashis?
Ekadashi is the eleventh tithi of each fortnight. The fast is kept on the day whose sunrise falls in the tithi. Two traditions can differ by a day: in the Smarta reckoning that day stands, and in the Vaishnava reckoning the fast moves to the next day when Dashami was still running at arunodaya (about an hour and a half before sunrise), or when the Dwadashi that follows holds two sunrises. Where the two differ, both days are shown. Each Ekadashi carries a name from its month and fortnight; an adhika (extra) month has Padmini and Parama.
Why does a date differ from my printed calendar?
Three reasons are common: the calendar was made for another city and the tithi started or ended close to sunrise there; it follows the other tradition for Ekadashi; or it uses a different ayanamsa or method. The tithi times on this page show which it is.
Can I see the panchang of any date?
Yes. Tap a day in the grid: its tithi, nakshatra, yoga, karana, sunrise and sunset, Rahu Kaal and choghadiya open under it, calculated for the chosen city. The months run a year back and two ahead.
