Panchang in Ipameri, Goiás, Brazil Wed 30 Mar 1994

The Sankashti fast is broken at moonrise. Chaturthi runs from 21:21 on Tue 29 Mar to 18:17 on Wed 30 Mar, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Wed 30 Mar. 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: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 06:18 here. Tritiya ended at 21:21 Tue, before it. Chaturthi ends at 18:17, when the lead reaches 228°. The lead passed 180° at the full moon of 27 Mar, so the Moon is waning: Krishna paksha.

The night of Tue 29 Mar ran from sunset 18:16 Tue to sunrise 06:18, 12 h 2 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 18:15, 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, 18:15 to 06:18 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 3 at 206°40′. It leaves at 16:56, for Anuradha.

Add the Sun's and the Moon's places among the stars: 345.7° + 206.8° = 552.5°, one full turn and 192.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 17:48, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Bava and the second Balava. Bava runs until 07:45, when the lead reaches 222°; Balava until 18:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:18 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 10 Apr, finds it in Meena and begins Chaitra.

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 10 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1993, 04:14 Tue. Since then the Sun has moved 366.8° round the stars. Vikram Samvat numbers that year 2050; Shaka Samvat numbers it 1915.
