Panchang in Ipameri, Goiás, Brazil Wed 15 Sep 1954

The Sankashti fast is broken at moonrise. Chaturthi runs from 07:34 on Wed 15 Sep to 04:24 on Thu 16 Sep, so it holds moonrise only on Wed 15 Sep, at 21:09. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 06:08 here. Dwitiya ended at 10:53 Tue, before it. Tritiya ends at 07:34, when the lead reaches 216°. The lead passed 180° at the full moon of 12 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 07:34 and ended at 04:24 Thu, between the sunrises of 06:08 and 06:07 Thu. Wednesday reads Tritiya and Thursday reads Panchami: Chaturthi is a kshaya tithi here.

The night of Tue 14 Sep ran from sunset 18:07 Tue to sunrise 06:08, 12 h 1 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:08 to 18:07, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 06:07 Thu, splits into 8 choghadiyas of 1 h 30 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 2 at 3°20′. It leaves at 21:21, for Bharani.

Add the Sun's and the Moon's places among the stars: 148.8° + 3.9° = 152.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 17:14, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija ended at 21:13 Tue, when the lead reached 210°; Vishti runs until 07:34.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:08 to 06:07 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 26 Sep, finds it in Kanya and begins Ashwina.

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 26 Sep, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 1954, 09:24 Sat. Since then the Sun has moved 158.8° round the stars. Vikram Samvat numbers that year 2011; Shaka Samvat numbers it 1876.
