Panchang in Codcod, Western Visayas, Philippines Wed 12 Dec 2035

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 18:16 on Wed 12 Dec to 15:28 on Thu 13 Dec, so it touches only Wednesday’s pradosha (17:26–19:56). No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 05:54 here. Ekadashi ended at 20:23 Tue, before it. Dwadashi ends at 18:16, when the lead reaches 144°. The lead passed 0° at the new moon of 30 Nov, so the Moon is waxing: Shukla paksha.

The night of Tue 11 Dec ran from sunset 17:25 Tue to sunrise 05:54, 12 h 29 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:54 to 17:26, 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, 17:26 to 05:55 Thu, 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 4 at 10°. It leaves at 07:20, for Bharani.

Add the Sun's and the Moon's places among the stars: 235.3° + 12.5° = 247.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 14:36, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava runs until 07:25, when the lead reaches 138°; Balava until 18:16.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:54 to 05:55 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, 29 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 30 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: 8 Apr 2035, 18:57 Sun. Since then the Sun has moved 241.2° round the stars. Vikram Samvat numbers that year 2092; Shaka Samvat numbers it 1957.
