Panchang in Thazhecode, Kerala Wed 14 Oct 2020

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 11:51 on Wed 14 Oct to 08:33 on Thu 15 Oct, so only Wednesday’s pradosha (18:08–20:33) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 06:15 here. Ekadashi ended at 14:36 Tue, before it. Dwadashi ends at 11:51, when the lead reaches 324°. The lead passed 180° at the full moon of 2 Oct, so the Moon is waning: Krishna paksha.

The night of Tue 13 Oct ran from sunset 18:09 Tue to sunrise 06:15, 12 h 6 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:15 to 18:08, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:08 to 06:15 Thu, splits into 8 choghadiyas of 1 h 30 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 2 at 136°40′. It leaves at 20:40, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 177° + 137.8° = 314.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 14:13, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 01:18, when the lead reached 318°; Taitila runs until 11:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:15 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Sep 16:30 Thu to 17 Oct 01:01 Sat the Sun stayed in Kanya, entering Tula at 17 Oct 07:05 Sat, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina itself.

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 17 Oct, with the Sun in Kanya, begins Ashwina (Adhik). Until then this Krishna paksha reads Ashwina (Adhik) here, and Ashwina (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2020, 14:58 Tue. Since then the Sun has moved 196.9° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
