Panchang in Sevan, Gegharkunik, Armenia Sat 21 Jul 1945

Smartas test Ekadashi at sunrise. It holds both sunrises, 04:45 on Fri 20 Jul and 04:46 on Sat 21 Jul. Ekadashi (03:31 Fri 20 Jul to 05:06 Sat 21 Jul) and Dwadashi (05:06 Sat 21 Jul to 06:07 Sun 22 Jul) are both longer than their day; when both grow, Smartas take the later day: Sat 21 Jul. Vaishnavas test arunodaya: on Fri 20 Jul Dashami lasts until 03:31, inside it (03:09–04:45); on Sat 21 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, 04:46 here. Dashami ended at 03:31 Fri, before it. Ekadashi ends at 05:06, when the lead reaches 132°. The lead passed 0° at the new moon of 9 Jul, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 03:31 Fri, before sunrise at 04:45 Fri, and ends at 05:06, after the next sunrise at 04:46. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 20 Jul ran from sunset 19:26 Fri to sunrise 04:46, 9 h 20 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:46 to 19:25, 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, 19:25 to 04:47 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 06:24 Sun, for Mula.

Add the Sun's and the Moon's places among the stars: 94.8° + 226.7° = 321.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 01:56 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 16:22 Fri, when the lead reached 126°; Vishti runs until 05:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:46 to 04:47 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, 8 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 9 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: 14 Mar 1945, 06:50 Wed. Since then the Sun has moved 124.7° round the stars. Vikram Samvat numbers that year 2002; Shaka Samvat numbers it 1867.
