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, 07:17 here. Pratipada ended at 05:07 Sun, before it. Dwitiya ends at 07:39, when the lead reaches 204°. The lead passed 180° at the full moon of 7 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Dwitiya began at 05:07 Sun, before sunrise at 07:17 Sun, and ends at 07:39, after the next sunrise at 07:17. Both days read Dwitiya: it is a vriddhi tithi here.

The night of Sun 8 Jan ran from sunset 17:09 Sun to sunrise 07:17, 14 h 8 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:17 to 17:10, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:10 to 07:17 Tue, splits into 8 choghadiyas of 1 h 45 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 07:01 Tue, for Magha.

Add the Sun's and the Moon's places among the stars: 264.4° + 108.2° = 372.6°, one full turn and 12.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 08:31, then Priti.

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 18:23 Sun, when the lead reached 198°; Garaja runs until 07:39.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:17 to 07:17 Tue, so the hours after midnight still belong to Somawara.

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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 22 Jan, finds it in Makara and begins Magha.

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 22 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 1 Apr 2022, 10:54 Fri. Since then the Sun has moved 277.1° round the stars. Vikram Samvat numbers that year 2079; Shaka Samvat numbers it 1944.
