Panchang in Sevan, Gegharkunik, Armenia Wed 14 Dec 2016

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 08:15 here. Purnima ended at 04:05, before it. Pratipada ends at 00:37 Thu, when the lead reaches 192°. The lead passed 180° at the full moon of 14 Dec, so the Moon is waning: Krishna paksha.

The night of Tue 13 Dec ran from sunset 17:33 Tue to sunrise 08:15, 14 h 42 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:15 to 17:33, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:33 to 08:16 Thu, splits into 8 choghadiyas of 1 h 50 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 3 at 60°. It leaves at 17:21, for Ardra.

Add the Sun's and the Moon's places among the stars: 238.5° + 61° = 299.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 19:00, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava runs until 14:19, when the lead reaches 186°; Kaulava until 00:37 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:15 to 08:16 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, 29 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 29 Dec, 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: 7 Apr 2016, 15:23 Thu. Since then the Sun has moved 244.5° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
