Panchang in Ipameri, Goiás, Brazil Fri 4 Sep 1936

The Sankashti fast is broken at moonrise. Chaturthi runs from 23:37 on Thu 3 Sep to 20:24 on Fri 4 Sep, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Fri 4 Sep. 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, 06:17 here. Tritiya ended at 23:37 Thu, before it. Chaturthi ends at 20:24, when the lead reaches 228°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 06:00, came before Tritiya ended at 08:07: this day reads Tritiya. Chaturthi ends at 04:54 Sat, before the next sunrise, so no day here reads Chaturthi: it is kshaya.

Sunrise here, 06:17, came after Tritiya ended at 23:37 Thu: this day reads Chaturthi.

The night of Thu 3 Sep ran from sunset 18:06 Thu to sunrise 06:17, 12 h 11 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:17 to 18:06, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:06 to 06:16 Sat, splits into 8 choghadiyas of 1 h 31 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 08:40, for Ashwini.

Add the Sun's and the Moon's places among the stars: 138.7° + 358.5° = 497.2°, one full turn and 137.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 20:42, then Dhruva.

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 09:59, when the lead reaches 222°; Balava until 20:24.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:17 to 06:16 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Aug 00:20 Mon to 15 Sep 14:41 Tue the Sun stayed in Simha, entering Kanya at 15 Sep 22:01 Tue, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 15 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 1936, 01:13 Mon. Since then the Sun has moved 159.3° round the stars. Vikram Samvat numbers that year 1993; Shaka Samvat numbers it 1858.
