Panchang in Sevan, Gegharkunik, Armenia Wed 12 Jun 2019

Ganga Dussehra follows the tithi at sunrise. Dashami runs from 18:49 on Tue 11 Jun to 16:57 on Wed 12 Jun, so it holds sunrise only on Wed 12 Jun, at 05:29. 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, 05:29 here. Navami ended at 18:49 Tue, before it. Dashami ends at 16:57, when the lead reaches 120°. The lead passed 0° at the new moon of 3 Jun, so the Moon is waxing: Shukla paksha.

The night of Tue 11 Jun ran from sunset 20:30 Tue to sunrise 05:29, 8 h 59 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:29 to 20:30, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:30 to 05:28 Thu, 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 4 at 170°. It leaves at 10:20, for Chitra.

Add the Sun's and the Moon's places among the stars: 56.7° + 170.5° = 227.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 02:07 Thu, then Parigha.

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 05:51, when the lead reaches 114°; Garaja until 16:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:29 to 05:28 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 2 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 3 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: 5 Apr 2019, 12:50 Fri. Since then the Sun has moved 65.5° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
