Panchang in Sevan, Gegharkunik, Armenia Sun 25 May 1980

Smartas test Ekadashi at sunrise: it holds sunrise on Sun 25 May only, at 05:35: Sun 25 May. Vaishnavas test arunodaya: Dashami ended at 17:18 Sat, before it (03:59–05:35).

Padmini Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 05:35 here. Dashami ended at 17:18 Sat, before it. Ekadashi ends at 19:43, when the lead reaches 132°. The lead passed 0° at the new moon of 14 May, so the Moon is waxing: Shukla paksha.

The night of Sat 24 May ran from sunset 20:17 Sat to sunrise 05:35, 9 h 18 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 20:18, splits into 8 choghadiyas of 1 h 50 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:18 to 05:34 Mon, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Hasta spans 160°00′–173°20′; the Moon entered its pada 2 at 163°20′. It leaves at 20:25, for Chitra.

Add the Sun's and the Moon's places among the stars: 40.4° + 166° = 206.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 18:32, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija runs until 06:32, when the lead reaches 126°; Vishti until 19:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:34 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 May 16:00 Wed to 13 Jun 00:38 Fri the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 16:25 Sat, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 14 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1980, 22:55 Sun. Since then the Sun has moved 67.6° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
