Panchang in Ipameri, Goiás, Brazil Sun 26 Sep 2010

The Sankashti fast is broken at moonrise. Chaturthi runs from 11:37 on Sun 26 Sep to 12:45 on Mon 27 Sep, so it holds moonrise only on Sun 26 Sep, at 20:59. 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, 05:59 here. Dwitiya ended at 10:08 Sat, before it. Tritiya ends at 11:37, when the lead reaches 216°. The lead passed 180° at the full moon of 23 Sep, so the Moon is waning: Krishna paksha.

The night of Sat 25 Sep ran from sunset 18:09 Sat to sunrise 05:59, 11 h 50 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:59 to 18:09, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:09 to 05:58 Mon, splits into 8 choghadiyas of 1 h 28 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 4 at 10°. It leaves at 07:37, for Bharani.

Add the Sun's and the Moon's places among the stars: 159.2° + 12.5° = 171.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 09:00, then Harshana.

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 22:55 Sat, when the lead reached 210°; Vishti runs until 11:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:59 to 05:58 Mon, so the hours after midnight still belong to Raviwara.

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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 7 Oct, finds it in Kanya and begins Ashwina.

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 Oct, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 2010, 18:01 Mon. Since then the Sun has moved 188° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
