Panchang in Sevan, Gegharkunik, Armenia Sat 22 Jul 1972

Smartas test Ekadashi at sunrise. It holds both sunrises, 05:46 on Fri 21 Jul and 05:47 on Sat 22 Jul. Ekadashi (05:31 Fri 21 Jul to 07:37 Sat 22 Jul) and Dwadashi (07:37 Sat 22 Jul to 09:20 Sun 23 Jul) are both longer than their day; when both grow, Smartas take the later day: Sat 22 Jul. Vaishnavas test arunodaya: on Fri 21 Jul Dashami lasts until 05:31, inside it (04:10–05:46); on Sat 22 Jul Ekadashi holds all of it.

Devshayani 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, 05:47 here. Dashami ended at 05:31 Fri, before it. Ekadashi ends at 07:37, when the lead reaches 132°. The lead passed 0° at the new moon of 10 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:31 Fri, before sunrise at 05:46 Fri, and ends at 07:37, after the next sunrise at 05:47. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 21 Jul ran from sunset 20:25 Fri to sunrise 05:47, 9 h 22 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:47 to 20:24, 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, 20:24 to 05:48 Sun, 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 1 at 226°40′. It leaves at 07:26 Sun, for Mula.

Add the Sun's and the Moon's places among the stars: 95.9° + 227° = 322.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 00:56 Sun, then Indra.

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 18:37 Fri, when the lead reached 126°; Vishti runs until 07:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:47 to 05:48 Sun, so the hours after midnight still belong to Shaniwara.

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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 9 Aug, finds it in Karka and begins Shravana.

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 10 Jul, with the Sun in Mithuna, began Ashadha. This Shukla paksha reads Ashadha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1972, 15:34 Wed. Since then the Sun has moved 124.4° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
