Panchang in Thazhecode, Kerala Fri 3 Dec 2021

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:30 here. Trayodashi ended at 20:26 Thu, before it. Chaturdashi ends at 16:56, when the lead reaches 348°. The lead passed 180° at the full moon of 19 Nov, so the Moon is waning: Krishna paksha.

The night of Thu 2 Dec ran from sunset 18:00 Thu to sunrise 06:30, 12 h 30 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:30 to 18:00, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:00 to 06:31 Sat, splits into 8 choghadiyas of 1 h 33 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 3 at 206°40′. It leaves at 13:44, for Anuradha.

Add the Sun's and the Moon's places among the stars: 226.9° + 208.8° = 435.7°, one full turn and 75.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 12:55, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti runs until 06:43, when the lead reaches 342°; Shakuni until 16:56.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:30 to 06:31 Sat, so the hours after midnight still belong to Shukrawara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 4 Dec, finds it in Vrishchika and begins Margashirsha.

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 4 Dec, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 2021, 08:00 Mon. Since then the Sun has moved 228.6° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
