Panchang in Ipameri, Goiás, Brazil Sat 19 Apr 2003

The Sankashti fast is broken at moonrise. Chaturthi runs from 05:45 on Sat 19 Apr to 02:47 on Sun 20 Apr, so it holds moonrise only on Sat 19 Apr, at 20:40. 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, 06:22 here. Tritiya ended at 05:45, before it. Chaturthi ends at 02:47 Sun, when the lead reaches 228°. The lead passed 180° at the full moon of 16 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

The night of Fri 18 Apr ran from sunset 18:01 Fri to sunrise 06:22, 12 h 21 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 to 18:00, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:00 to 06:23 Sun, splits into 8 choghadiyas of 1 h 32 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 3 at 220°. It leaves at 14:59, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 5° + 221.4° = 226.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 06:47, then Variyana.

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 16:12, when the lead reaches 222°; Balava until 02:47 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:22 to 06:23 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 1 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 1 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: 1 Apr 2003, 16:18 Tue. Since then the Sun has moved 17.2° round the stars. Vikram Samvat numbers that year 2060; Shaka Samvat numbers it 1925.
