Panchang in Codcod, Western Visayas, Philippines Thu 11 Apr 2086

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 11:47 on Thu 11 Apr to 08:13 on Fri 12 Apr, so only Thursday’s pradosha (17:57–20:17) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 05:38 here. Ekadashi ended at 15:04 Wed, before it. Dwadashi ends at 11:47, when the lead reaches 324°. The lead passed 180° at the full moon of 30 Mar, so the Moon is waning: Krishna paksha.

The night of Wed 10 Apr ran from sunset 17:57 Wed to sunrise 05:38, 11 h 41 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:38 to 17:57, 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 night here, 17:57 to 05:38 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 4 at 316°40′. It leaves at 10:42, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 356.4° + 316.8° = 673.2°, one full turn and 313.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 15:46, 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 01:28, when the lead reached 318°; Taitila runs until 11:47.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:38 to 05:38 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Mar 16:05 Fri to 14 Apr 00:54 Sun the Sun stayed in Meena, entering Mesha at 14 Apr 21:05 Sun, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra 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 14 Apr, with the Sun in Meena, begins Chaitra (Adhik). Until then this Krishna paksha reads Chaitra (Adhik) here, and Chaitra (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 2086, 16:05 Fri. Since then the Sun has moved 26.3° round the stars. Vikram Samvat numbers that year 2143; Shaka Samvat numbers it 2008.
