Panchang in Ipameri, Goiás, Brazil Mon 4 May 1931

The Sankashti fast is broken at moonrise. Chaturthi runs from 19:52 on Mon 4 May to 18:58 on Tue 5 May, so it holds moonrise only on Mon 4 May, at 20:00. 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, 06:26 here. Dwitiya ended at 21:27 Sun, before it. Tritiya ends at 19:52, when the lead reaches 216°. The lead passed 180° at the full moon of 2 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 05:38, came before Dwitiya ended at 05:57: this day reads Dwitiya. Tritiya ends at 04:22 Tue, before the next sunrise, so no day here reads Tritiya: it is kshaya.

Sunrise here, 06:26, came after Dwitiya ended at 21:27 Sun: this day reads Tritiya.

The night of Sun 3 May ran from sunset 17:52 Sun to sunrise 06:26, 12 h 34 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:26 to 17:52, splits into 8 choghadiyas of 1 h 25 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:52 to 06:26 Tue, 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 1 at 226°40′. It leaves at 01:53 Tue, for Mula.

Add the Sun's and the Moon's places among the stars: 20.1° + 228.9° = 249°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 13:32, then Shiva.

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 runs until 08:35, when the lead reaches 210°; Vishti until 19:52.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:26 to 06:26 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, 17 May, 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 17 May, 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: 19 Mar 1931, 04:50 Thu. Since then the Sun has moved 45.2° round the stars. Vikram Samvat numbers that year 1988; Shaka Samvat numbers it 1853.
