Panchang in Sevan, Gegharkunik, Armenia Thu 23 Sep 1920

Smartas test Ekadashi at sunrise: it holds sunrise on Thu 23 Sep only, at 05:45: Thu 23 Sep. Vaishnavas test arunodaya: Dashami ended at 01:43, before it (04:09–05:45).

Parsva 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 01:45, before it. Ekadashi ends at 03:30 Fri, when the lead reaches 132°. The lead passed 0° at the new moon of 12 Sep, so the Moon is waxing: Shukla paksha.

The night of Wed 22 Sep ran from sunset 17:58 Wed to sunrise 05:47, 11 h 49 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:47 to 17:56, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:56 to 05:48 Fri, splits into 8 choghadiyas of 1 h 29 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 4 at 276°40′. It leaves at 08:00, for Shravana.

Add the Sun's and the Moon's places among the stars: 157° + 278.9° = 435.9°, one full turn and 75.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 13:18, then Sukarma.

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 14:41, when the lead reaches 126°; Vishti until 03:30 Fri.

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

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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 12 Oct, finds it in Kanya and begins Ashwina.

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 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1920, 13:55 Sat. Since then the Sun has moved 180.2° round the stars. Vikram Samvat numbers that year 1977; Shaka Samvat numbers it 1842.
