Panchang in Ipameri, Goiás, Brazil Wed 12 Dec 2040

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 96°–108° is the 9th, Shukla Navami. A day takes the tithi in force at its sunrise, 05:31 here. Ashtami ended at 07:43 Tue, before it. Navami ends at 06:32, when the lead reaches 108°. The lead passed 0° at the new moon of 4 Dec, so the Moon is waxing: Shukla paksha.

The night of Tue 11 Dec ran from sunset 18:41 Tue to sunrise 05:31, 10 h 50 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:31 to 18:42, 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, 18:42 to 05:31 Thu, 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 4 at 343°20′. It leaves at 10:19, for Revati.

Add the Sun's and the Moon's places among the stars: 236.5° + 344° = 580.5°, one full turn and 220.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 15:47, then Variyana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Balava and the second Kaulava. Balava ended at 19:04 Tue, when the lead reached 102°; Kaulava runs until 06:32.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:31 to 05:31 Thu, so the hours after midnight still belong to Budhawara.

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, 2 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 4 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: 11 Apr 2040, 11:00 Wed. Since then the Sun has moved 238.6° round the stars. Vikram Samvat numbers that year 2097; Shaka Samvat numbers it 1962.
