Panchang in Ipameri, Goiás, Brazil Sat 27 May 1939

Ganga Dussehra follows the tithi at sunrise. Dashami runs from 05:17 on Sat 27 May to 03:35 on Sun 28 May, so it holds sunrise only on Sat 27 May, at 06:34. 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: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 06:34 here. Navami ended at 05:17, before it. Dashami ends at 03:35 Sun, when the lead reaches 120°. The lead passed 0° at the new moon of 19 May, so the Moon is waxing: Shukla paksha.

The night of Fri 26 May ran from sunset 17:45 Fri to sunrise 06:34, 12 h 49 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 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 06:34 Sun, 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 2 at 150°. It leaves at 22:18, for Hasta.

Add the Sun's and the Moon's places among the stars: 42.2° + 150.9° = 193.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 17:44, then Siddhi.

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 16:24, when the lead reaches 114°; Garaja until 03:35 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:34 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 14 Jun, inside the month. The next new moon, 17 Jun, 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 19 May, 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: 20 Mar 1939, 22:49 Mon. Since then the Sun has moved 65.7° round the stars. Vikram Samvat numbers that year 1996; Shaka Samvat numbers it 1861.
