Panchang in Sevan, Gegharkunik, Armenia Wed 21 May 1975

Smartas test Ekadashi at sunrise: it holds sunrise on Wed 21 May only, at 05:39: Wed 21 May. Vaishnavas test arunodaya: Dashami ended at 20:28 Tue, before it (04:03–05:39).

Mohini 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, 05:39 here. Dashami ended at 20:28 Tue, before it. Ekadashi ends at 17:59, when the lead reaches 132°. The lead passed 0° at the new moon of 11 May, so the Moon is waxing: Shukla paksha.

The night of Tue 20 May ran from sunset 20:13 Tue to sunrise 05:39, 9 h 26 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:39 to 20:14, splits into 8 choghadiyas of 1 h 49 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:14 to 05:38 Thu, splits into 8 choghadiyas of 1 h 10 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 1 at 160°. It leaves at 02:17 Thu, for Chitra.

Add the Sun's and the Moon's places among the stars: 35.9° + 161° = 196.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 10:30, then Siddhi.

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 07:14, when the lead reaches 126°; Vishti until 17:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:39 to 05:38 Thu, so the hours after midnight still belong to Budhawara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 9 Jun, finds it in Vrishabha and begins Jyeshtha.

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 11 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1975, 20:38 Fri. Since then the Sun has moved 38.2° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
