Panchang in Codcod, Western Visayas, Philippines Tue 13 Nov 2035

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:31 on Tue 13 Nov to 02:53 on Wed 14 Nov, so only Tuesday’s pradosha (17:21–19:49) falls within it. 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: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 05:41 here. Dwadashi ended at 04:31, before it. Trayodashi ends at 02:53 Wed, when the lead reaches 156°. The lead passed 0° at the new moon of 31 Oct, so the Moon is waxing: Shukla paksha.

The night of Mon 12 Nov ran from sunset 17:21 Mon to sunrise 05:41, 12 h 20 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:41 to 17:21, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:21 to 05:41 Wed, splits into 8 choghadiyas of 1 h 32 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 2 at 350°. It leaves at 22:00, for Ashwini.

Add the Sun's and the Moon's places among the stars: 206° + 350.6° = 556.6°, one full turn and 196.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 11:17, then Siddhi.

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 15:47, when the lead reaches 150°; Taitila until 02:53 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:41 to 05:41 Wed, so the hours after midnight still belong to Mangalawara.

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 17 Nov, inside the month. The next new moon, 30 Nov, 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 31 Oct, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika 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 211.9° round the stars. Vikram Samvat numbers that year 2092; Shaka Samvat numbers it 1957.
