Panchang in Thazhecode, Kerala Sat 11 Dec 2027

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 02:53 on Sat 11 Dec to 01:43 on Sun 12 Dec, so only Saturday’s pradosha (18:03–20:33) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Thazhecode

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 06:34 here. Dwadashi ended at 02:53, before it. Trayodashi ends at 01:43 Sun, when the lead reaches 156°. The lead passed 0° at the new moon of 28 Nov, so the Moon is waxing: Shukla paksha.

The night of Fri 10 Dec ran from sunset 18:03 Fri to sunrise 06:34, 12 h 31 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:34 to 18:03, 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, 18:03 to 06:35 Sun, splits into 8 choghadiyas of 1 h 34 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 3 at 20°. It leaves at 17:38, for Krittika.

Add the Sun's and the Moon's places among the stars: 234.5° + 20.4° = 254.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 01:49 Sun, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava runs until 14:23, when the lead reaches 150°; Taitila until 01:43 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:34 to 06:35 Sun, so the hours after midnight still belong to Shaniwara.

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, 28 Dec, 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 28 Nov, 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: 7 Apr 2027, 05:21 Wed. Since then the Sun has moved 241.8° round the stars. Vikram Samvat numbers that year 2084; Shaka Samvat numbers it 1949.
