Panchang in Ipameri, Goiás, Brazil Thu 23 Dec 1926

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, 05:35 here. Tritiya ended at 04:12 Wed, before it. Chaturthi ends at 05:45, when the lead reaches 228°. The lead passed 180° at the full moon of 19 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturthi began at 04:12 Wed, before sunrise at 05:35 Wed, and ends at 05:45, after the next sunrise at 05:35. Both days read Chaturthi: it is a vriddhi tithi here.

The night of Wed 22 Dec ran from sunset 18:47 Wed to sunrise 05:35, 10 h 48 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 18:47, splits into 8 choghadiyas of 1 h 39 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:47 to 05:36 Fri, splits into 8 choghadiyas of 1 h 21 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 3 at 113°20′. It leaves at 13:46, for Magha.

Add the Sun's and the Moon's places among the stars: 247.9° + 115.9° = 363.8°, one full turn and 3.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 23:02, then Priti.

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 16:54 Wed, when the lead reached 222°; Balava runs until 05:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:36 Fri, so the hours after midnight still belong to Guruwara.

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 3 Jan, finds it in Dhanu and begins Pausha.

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 3 Jan, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 1926, 09:56 Mon. Since then the Sun has moved 248.9° round the stars. Vikram Samvat numbers that year 1983; Shaka Samvat numbers it 1848.
