Panchang in Sevan, Gegharkunik, Armenia Fri 22 May 1964

Smartas test Ekadashi at sunrise. It holds both sunrises, 05:38 on Thu 21 May and 05:37 on Fri 22 May. Ekadashi (04:40 Thu 21 May to 05:39 Fri 22 May) and Dwadashi (05:39 Fri 22 May to 07:05 Sat 23 May) are both longer than their day; when both grow, Smartas take the later day: Fri 22 May. Vaishnavas test arunodaya: on Thu 21 May Dashami lasts until 04:40, inside it (04:02–05:38); on Fri 22 May Ekadashi holds all of it.

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, 05:37 here. Dashami ended at 04:40 Thu, before it. Ekadashi ends at 05:39, when the lead reaches 132°. The lead passed 0° at the new moon of 12 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:40 Thu, before sunrise at 05:38 Thu, and ends at 05:39, after the next sunrise at 05:37. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Thu 21 May ran from sunset 20:15 Thu to sunrise 05:37, 9 h 22 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 20:15, 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, 20:15 to 05:36 Sat, 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 3 at 166°40′. It leaves at 12:49, for Chitra.

Add the Sun's and the Moon's places among the stars: 37.6° + 169.6° = 207.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 16:34, 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 ended at 17:05 Thu, when the lead reached 126°; Vishti runs until 05:39.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:36 Sat, so the hours after midnight still belong to Shukrawara.

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 14 May, inside the month. The next new moon, 10 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 12 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: 14 Mar 1964, 06:13 Sat. Since then the Sun has moved 67.4° round the stars. Vikram Samvat numbers that year 2021; Shaka Samvat numbers it 1886.
