Panchang in Ipameri, Goiás, Brazil Mon 4 Nov 1963

The Sankashti fast is broken at moonrise. Chaturthi runs from 00:50 on Mon 4 Nov to 21:52 on Mon 4 Nov, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Mon 4 Nov. 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, 06:32 here. Tritiya ended at 00:50, before it. Chaturthi ends at 21:52, when the lead reaches 228°. The lead passed 180° at the full moon of 1 Nov, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 06:34, came before Tritiya ended at 08:20: this day reads Tritiya. Chaturthi ends at 05:22 Tue, before the next sunrise, so no day here reads Chaturthi: it is kshaya.

Sunrise here, 06:32, came after Tritiya ended at 00:50: this day reads Chaturthi.

The night of Sun 3 Nov ran from sunset 19:19 Sun to sunrise 06:32, 11 h 13 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:32 to 19:20, 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 night here, 19:20 to 06:32 Tue, splits into 8 choghadiyas of 1 h 24 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 2 at 56°40′. It leaves at 22:09, for Ardra.

Add the Sun's and the Moon's places among the stars: 197.9° + 57.1° = 255°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 00:28 Tue, then Siddha.

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 11:17, when the lead reaches 222°; Balava until 21:52.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:32 to 06:32 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Oct 09:42 Thu to 16 Nov 04:50 Sat the Sun stayed in Tula, entering Vrishchika at 16 Nov 08:39 Sat, after the new moon. A month with no sankranti is Adhika Kartika, before Kartika itself.

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 16 Nov, with the Sun in Tula, begins Kartika (Adhik). Until then this Krishna paksha reads Kartika (Adhik) here, and Kartika (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1963, 09:09 Mon. Since then the Sun has moved 217.1° round the stars. Vikram Samvat numbers that year 2020; Shaka Samvat numbers it 1885.
