The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 36°–48° is the 4th, Shukla Chaturthi. A day takes the tithi in force at its sunrise, 08:14 here. Tritiya ended at 02:20, before it. Chaturthi ends at 03:11 Fri, when the lead reaches 48°. The lead passed 0° at the new moon of 9 Dec, so the Moon is waxing: Shukla paksha.

The night of Wed 12 Dec ran from sunset 17:33 Wed to sunrise 08:14, 14 h 41 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:14 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 08:15 Fri, 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 3 at 273°20′. It leaves at 16:35, for Shravana.

Add the Sun's and the Moon's places among the stars: 236.8° + 275.6° = 512.4°, one full turn and 152.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 21:36, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Vanija and the second Vishti. Vanija runs until 14:48, when the lead reaches 42°; Vishti until 03:11 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:14 to 08:15 Fri, so the hours after midnight still belong to Guruwara.

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, 8 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 9 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: 19 Mar 2007, 06:42 Mon. Since then the Sun has moved 262.6° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
