Panchang in Ipameri, Goiás, Brazil Mon 24 Apr 1989

The Sankashti fast is broken at moonrise. Chaturthi runs from 05:18 on Mon 24 Apr to 06:15 on Tue 25 Apr, so it holds moonrise only on Mon 24 Apr, at 20:28. 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, 06:24 here. Tritiya ended at 05:18, before it. Chaturthi ends at 06:15 Tue, when the lead reaches 228°. The lead passed 180° at the full moon of 21 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

The night of Sun 23 Apr ran from sunset 17:58 Sun to sunrise 06:24, 12 h 26 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:24 to 17:57, 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, 17:57 to 06:24 Tue, splits into 8 choghadiyas of 1 h 33 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 07:20 Tue, for Mula.

Add the Sun's and the Moon's places among the stars: 10.5° + 227° = 237.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 10:58, then Parigha.

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 17:50, when the lead reaches 222°; Balava until 06:15 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:24 to 06:24 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 5 May, finds it in Mesha and begins Vaishakha.

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 5 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 6 Apr 1989, 00:32 Thu. Since then the Sun has moved 17.9° round the stars. Vikram Samvat numbers that year 2046; Shaka Samvat numbers it 1911.
