Panchang in Ipameri, Goiás, Brazil Tue 10 Dec 2019

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 05:30 here. Trayodashi ended at 02:13, before it. Chaturdashi ends at 02:29 Wed, when the lead reaches 168°. The lead passed 0° at the new moon of 26 Nov, so the Moon is waxing: Shukla paksha.

The night of Mon 9 Dec ran from sunset 18:39 Mon to sunrise 05:30, 10 h 51 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 05:30 Wed, 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 2 at 30°. It leaves at 21:27, for Rohini.

Add the Sun's and the Moon's places among the stars: 233.8° + 31.4° = 265.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 07:54, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja runs until 14:25, when the lead reaches 162°; Vanija until 02:29 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:30 to 05:30 Wed, so the hours after midnight still belong to Mangalawara.

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 16 Dec, inside the month. The next new moon, 26 Dec, 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 26 Nov, 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: 5 Apr 2019, 05:50 Fri. Since then the Sun has moved 242.6° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
