Panchang in Sevan, Gegharkunik, Armenia Mon 28 Sep 2009

Dussehra’s rites are done in aparahna, the fourth fifth of the day. Dashami runs from 01:36 on Mon 28 Sep to 04:12 on Tue 29 Sep, so only Monday’s aparahna (15:01–17:24) 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, 07:53 here. Navami ended at 01:36, before it. Dashami ends at 04:12 Tue, when the lead reaches 120°. The lead passed 0° at the new moon of 18 Sep, so the Moon is waxing: Shukla paksha.

The night of Sun 27 Sep ran from sunset 19:49 Sun to sunrise 07:53, 12 h 4 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:53 to 19:47, 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 night here, 19:47 to 07:54 Tue, splits into 8 choghadiyas of 1 h 30 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 2 at 270°. It leaves at 00:13 Tue, for Shravana.

Add the Sun's and the Moon's places among the stars: 161.1° + 272° = 433.1°, one full turn and 73.1°. 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 20:51, then Sukarma.

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 14:55, when the lead reaches 114°; Garaja until 04:12 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:53 to 07:54 Tue, so the hours after midnight still belong to Somawara.

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 17 Oct, inside the month. The next new moon, 18 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 18 Sep, 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: 26 Mar 2009, 20:05 Thu. Since then the Sun has moved 179° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
