Panchang in Ipameri, Goiás, Brazil Mon 31 May 1915

The Sankashti fast is broken at moonrise. Chaturthi runs from 07:41 on Mon 31 May to 05:01 on Tue 1 Jun, so it holds moonrise only on Mon 31 May, at 20:47. 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, 06:35 here. Dwitiya ended at 10:57 Sun, before it. Tritiya ends at 07:41, when the lead reaches 216°. The lead passed 180° at the full moon of 28 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 07:41 and ended at 05:01 Tue, between the sunrises of 06:35 and 06:36 Tue. Monday reads Tritiya and Tuesday reads Panchami: Chaturthi is a kshaya tithi here.

The night of Sun 30 May ran from sunset 17:44 Sun to sunrise 06:35, 12 h 51 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:35 to 17:44, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:44 to 06:36 Tue, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 3 at 260°. It leaves at 15:00, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 46.2° + 261.5° = 307.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 01:38 Tue, then Brahma.

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 21:15 Sun, when the lead reached 210°; Vishti runs until 07:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:35 to 06:36 Tue, so the hours after midnight still belong to Somawara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 12 Jun, finds it in Vrishabha and begins Jyeshtha.

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 12 Jun, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha 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 74.7° round the stars. Vikram Samvat numbers that year 1972; Shaka Samvat numbers it 1837.
