Panchang in Myshkin, Yaroslavl Oblast, Russia Sat 11 Jun 2011

Ganga Dussehra follows the tithi at sunrise. Dashami runs from 14:37 on Fri 10 Jun to 12:03 on Sat 11 Jun, so it holds sunrise only on Sat 11 Jun, at 04:26. No text giving Ganga Dussehra’s time was found; sunrise is Tithika’s convention.

Ganga Dussehra: every date in Myshkin

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, 04:26 here. Navami ended at 14:37 Fri, before it. Dashami ends at 12:03, when the lead reaches 120°. The lead passed 0° at the new moon of 2 Jun, so the Moon is waxing: Shukla paksha.

The night of Fri 10 Jun ran from sunset 22:24 Fri to sunrise 04:26, 6 h 2 m. Cut into 15 muhurtas of 24 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:26 to 22:25, splits into 8 choghadiyas of 2 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 22:25 to 04:25 Sun, splits into 8 choghadiyas of 45 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 07:31, for Chitra.

Add the Sun's and the Moon's places among the stars: 55.8° + 171.5° = 227.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 00:20 Sun, 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 ended at 01:21, when the lead reached 114°; Garaja runs until 12:03.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:26 to 04:25 Sun, so the hours after midnight still belong to Shaniwara.

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, 1 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 2 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: 3 Apr 2011, 18:32 Sun. Since then the Sun has moved 66.3° round the stars. Vikram Samvat numbers that year 2068; Shaka Samvat numbers it 1933.
