Panchang in Ipameri, Goiás, Brazil Sun 10 Dec 2045

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 12°–24° is the 2nd, Shukla Dwitiya. A day takes the tithi in force at its sunrise, 05:30 here. Pratipada ended at 08:52 Sat, before it. Dwitiya ends at 09:39, when the lead reaches 24°. The lead passed 0° at the new moon of 8 Dec, so the Moon is waxing: Shukla paksha.

The night of Sat 9 Dec ran from sunset 18:40 Sat to sunrise 05:30, 10 h 50 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:30 to 18:40, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:40 to 05:31 Mon, 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′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 1 at 253°20′. It leaves at 01:44 Mon, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 234.2° + 256.2° = 490.4°, one full turn and 130.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 10:46, then Vriddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwitiya is Balava and the second Kaulava. Balava ended at 21:11 Sat, when the lead reached 18°; Kaulava runs until 09:39.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:30 to 05:31 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 7 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 8 Dec, with the Sun in Vrishchika, began Margashirsha. This Shukla paksha reads Margashirsha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 2045, 14:14 Sat. Since then the Sun has moved 260.2° round the stars. Vikram Samvat numbers that year 2102; Shaka Samvat numbers it 1967.
