Panchang in Sevan, Gegharkunik, Armenia Fri 22 Oct 1920

Dussehra’s rites are done in aparahna, the fourth fifth of the day. Dashami runs from 18:33 on Thu 21 Oct to 19:58 on Fri 22 Oct, so only Friday’s aparahna (12:47–14:58) falls within it.

Dussehra: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 06:18 here. Navami ended at 18:35 Thu, before it. Dashami ends at 20:00, when the lead reaches 120°. The lead passed 0° at the new moon of 12 Oct, so the Moon is waxing: Shukla paksha.

The night of Thu 21 Oct ran from sunset 17:11 Thu to sunrise 06:18, 13 h 7 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 17:10, splits into 8 choghadiyas of 1 h 21 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:10 to 06:19 Sat, splits into 8 choghadiyas of 1 h 38 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 2 at 296°40′. It leaves at 20:49, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 185.7° + 299.2° = 484.9°, one full turn and 124.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 21:31, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila runs until 07:22, when the lead reaches 114°; Garaja until 20:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:19 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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 10 Nov, 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 12 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: 20 Mar 1920, 13:55 Sat. Since then the Sun has moved 208.9° round the stars. Vikram Samvat numbers that year 1977; Shaka Samvat numbers it 1842.
