The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 192°–204° is the 17th, Krishna Dwitiya. A day takes the tithi in force at its sunrise, 08:19 here. Pratipada ended at 11:07 Mon, before it. Dwitiya ends at 13:24, when the lead reaches 204°. The lead passed 180° at the full moon of 19 Dec, so the Moon is waning: Krishna paksha.

The night of Mon 20 Dec ran from sunset 17:35 Mon to sunrise 08:19, 14 h 44 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:19 to 17:36, 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, 17:36 to 08:20 Wed, 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 3 at 86°40′. It leaves at 20:55, for Pushya.

Add the Sun's and the Moon's places among the stars: 245.3° + 87° = 332.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 10:06, then Indra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwitiya is Taitila and the second Garaja. Taitila ended at 00:17, when the lead reached 198°; Garaja runs until 13:24.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:19 to 08:20 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, 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 2 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 2021, 06:30 Mon. Since then the Sun has moved 247° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
