Panchang in Sevan, Gegharkunik, Armenia Wed 12 Oct 1921

Smartas test Ekadashi at sunrise: it holds sunrise on Wed 12 Oct only, at 06:04: Wed 12 Oct. Vaishnavas test arunodaya: Dashami ended at 16:58 Tue, before it (04:28–06:04).

Papankusha 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, 06:06 here. Dashami ended at 17:00 Tue, before it. Ekadashi ends at 19:27, when the lead reaches 132°. The lead passed 0° at the new moon of 1 Oct, so the Moon is waxing: Shukla paksha.

The night of Tue 11 Oct ran from sunset 17:27 Tue to sunrise 06:06, 12 h 39 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:06 to 17:25, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:25 to 06:07 Thu, splits into 8 choghadiyas of 1 h 35 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 3 at 300°. It leaves at 16:41, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 175.5° + 301.4° = 476.9°, one full turn and 116.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 11:52, then Ganda.

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 06:15, when the lead reaches 126°; Vishti until 19:27.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:06 to 06:07 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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 31 Oct, finds it in Tula and begins Kartika.

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 1 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 1921, 12:04 Fri. Since then the Sun has moved 180.3° round the stars. Vikram Samvat numbers that year 1978; Shaka Samvat numbers it 1843.
