Panchang in Ipameri, Goiás, Brazil Sun 2 May 1915

The Sankashti fast is broken at moonrise. Chaturthi runs from 00:01 on Sun 2 May to 20:48 on Sun 2 May, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Sun 2 May. 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, 06:25 here. Tritiya ended at 00:01, before it. Chaturthi ends at 20:48, when the lead reaches 228°. The lead passed 180° at the full moon of 29 Apr, so the Moon is waning: Krishna paksha.

Sunrise here, 05:40, came before Tritiya ended at 08:31: this day reads Tritiya. Chaturthi ends at 05:18 Mon, before the next sunrise, so no day here reads Chaturthi: it is kshaya.

The night of Sat 1 May ran from sunset 17:53 Sat to sunrise 06:25, 12 h 32 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:25 to 17:53, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:53 to 06:26 Mon, splits into 8 choghadiyas of 1 h 34 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 4 at 236°40′. It leaves at 09:44, for Mula.

Add the Sun's and the Moon's places among the stars: 18.2° + 238° = 256.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 22:26, 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 10:21, when the lead reaches 222°; Balava until 20:48.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:25 to 06:26 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 08:35 Wed to 14 May 00:30 Fri the Sun stayed in Mesha, entering Vrishabha at 14 May 10:42 Fri, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 14 May, with the Sun in Mesha, begins Vaishakha (Adhik). Until then this Krishna paksha reads Vaishakha (Adhik) here, and Vaishakha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1915, 16:41 Mon. Since then the Sun has moved 46.7° round the stars. Vikram Samvat numbers that year 1972; Shaka Samvat numbers it 1837.
