Panchang in Ipameri, Goiás, Brazil Sat 26 Jul 1975

The Sankashti fast is broken at moonrise. Chaturthi runs from 07:40 on Sat 26 Jul to 10:00 on Sun 27 Jul, so it holds moonrise only on Sat 26 Jul, at 20:54. 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, 06:41 here. Dwitiya ended at 05:35 Fri, before it. Tritiya ends at 07:40, when the lead reaches 216°. The lead passed 180° at the full moon of 23 Jul, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Tritiya began at 05:35 Fri, before sunrise at 06:41 Fri, and ends at 07:40, after the next sunrise at 06:41. Both days read Tritiya: it is a vriddhi tithi here.

The night of Fri 25 Jul ran from sunset 17:56 Fri to sunrise 06:41, 12 h 45 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 17:57, 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 night here, 17:57 to 06:41 Sun, splits into 8 choghadiyas of 1 h 35 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 3 at 313°20′. It leaves at 17:06, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 99.3° + 314.8° = 414.1°, one full turn and 54.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 06:08 Sun, then Atiganda.

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 18:36 Fri, when the lead reached 210°; Vishti runs until 07:40.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:41 Sun, so the hours after midnight still belong to Shaniwara.

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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 7 Aug, finds it in Karka and begins Shravana.

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 7 Aug, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1975, 13:38 Fri. Since then the Sun has moved 101.6° round the stars. Vikram Samvat numbers that year 2032; Shaka Samvat numbers it 1897.
