Panchang in Simrishamn, Skåne, Sweden Wed 13 Dec 2023

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 08:22 here. Amavasya ended at 00:32, before it. Pratipada ends at 22:39, when the lead reaches 12°. The lead passed 0° at the new moon of 13 Dec, so the Moon is waxing: Shukla paksha.

The night of Tue 12 Dec ran from sunset 15:30 Tue to sunrise 08:22, 16 h 52 m. Cut into 15 muhurtas of 1 h 7 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:22 to 15:29, splits into 8 choghadiyas of 53 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 15:29 to 08:23 Thu, splits into 8 choghadiyas of 2 h 6 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 05:16 Thu, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 236.8° + 241° = 477.8°, one full turn and 117.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 11:47, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna runs until 11:39, when the lead reaches 6°; Bava until 22:39.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:22 to 08:23 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 16 Dec, inside the month. The next new moon, 11 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 13 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: 21 Mar 2023, 18:23 Tue. Since then the Sun has moved 260.2° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
