Panchang in Sevan, Gegharkunik, Armenia Mon 25 Jun 2007

Ganga Dussehra follows the tithi at sunrise. Dashami runs from 09:51 on Sun 24 Jun to 12:17 on Mon 25 Jun, so it holds sunrise only on Mon 25 Jun, at 06:30. No text giving Ganga Dussehra’s time was found; sunrise is Tithika’s convention.

Ganga 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, 06:30 here. Navami ended at 09:51 Sun, before it. Dashami ends at 12:17, when the lead reaches 120°. The lead passed 0° at the new moon of 15 Jun, so the Moon is waxing: Shukla paksha.

The night of Sun 24 Jun ran from sunset 21:34 Sun to sunrise 06:30, 8 h 56 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:30 to 21:34, splits into 8 choghadiyas of 1 h 53 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:34 to 06:30 Tue, splits into 8 choghadiyas of 1 h 7 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 4 at 183°20′. It leaves at 06:42, for Swati.

Add the Sun's and the Moon's places among the stars: 69.2° + 186.6° = 255.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 02:52 Tue, then Siddha.

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 ended at 23:05 Sun, when the lead reached 114°; Garaja runs until 12:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:30 to 06:30 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 14 Jul, finds it in Mithuna and begins Ashadha.

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 15 Jun, with the Sun in Vrishabha, began Jyeshtha. This Shukla paksha reads Jyeshtha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 2007, 06:42 Mon. Since then the Sun has moved 95° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
