Panchang in Ipameri, Goiás, Brazil Sat 23 Jul 2016

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, 06:42 here. Tritiya ended at 16:47 Fri, before it. Chaturthi ends at 15:08, when the lead reaches 228°. The lead passed 180° at the full moon of 19 Jul, so the Moon is waning: Krishna paksha.

The night of Fri 22 Jul ran from sunset 17:56 Fri to sunrise 06:42, 12 h 46 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:42 to 17:56, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:56 to 06:41 Sun, splits into 8 choghadiyas of 1 h 35 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 Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 1 at 320°. It leaves at 05:07 Sun, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 96.9° + 320.3° = 417.2°, one full turn and 57.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 21:59, then Atiganda.

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 ended at 03:59, when the lead reached 222°; Balava runs until 15:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:42 to 06:41 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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 2 Aug, finds it in Karka and begins Shravana.

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 2 Aug, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 08:23 Thu. Since then the Sun has moved 102.9° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
