Panchang in Ipameri, Goiás, Brazil Fri 14 Jun 1940

Ganga Dussehra follows the tithi at sunrise. Dashami begins at 07:42 on Fri 14 Jun, after that sunrise, and ends at 05:29 on Sat 15 Jun, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Fri 14 Jun. No text giving Ganga Dussehra’s time was found; sunrise is Tithika’s convention.

Ganga Dussehra: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 06:40 here. Ashtami ended at 09:54 Thu, before it. Navami ends at 07:42, when the lead reaches 108°. The lead passed 0° at the new moon of 5 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Dashami began at 07:42 and ended at 05:29 Sat, between the sunrises of 06:40 and 06:40 Sat. Friday reads Navami and Saturday reads Ekadashi: Dashami is a kshaya tithi here.

The night of Thu 13 Jun ran from sunset 17:45 Thu to sunrise 06:40, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 to 17:45, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:45 to 06:40 Sat, splits into 8 choghadiyas of 1 h 36 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 3 at 166°40′. It leaves at 16:26, for Chitra.

Add the Sun's and the Moon's places among the stars: 60.1° + 167.6° = 227.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 02:10 Sat, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava ended at 20:48 Thu, when the lead reached 102°; Kaulava runs until 07:42.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 to 06:40 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 5 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 5 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: 7 Apr 1940, 17:18 Sun. Since then the Sun has moved 65.3° round the stars. Vikram Samvat numbers that year 1997; Shaka Samvat numbers it 1862.
