Panchang in Codcod, Western Visayas, Philippines Tue 10 Apr 1945

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 08:40 on Tue 10 Apr to 05:13 on Wed 11 Apr, so only Tuesday’s pradosha (18:57–21:18) 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, 06:39 here. Ekadashi ended at 11:38 Mon, before it. Dwadashi ends at 08:40, when the lead reaches 324°. The lead passed 180° at the full moon of 29 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 08:40 and ended at 05:13 Wed, between the sunrises of 06:39 and 06:39 Wed. Tuesday reads Dwadashi and Wednesday reads Chaturdashi: Trayodashi is a kshaya tithi here.

Codcod · UTC+9

Sunrise here, 06:39, came before Dwadashi ended at 08:40: this day reads Dwadashi. Trayodashi ends at 05:13 Wed, before the next sunrise, so no day here reads Trayodashi: it is kshaya.

The night of Mon 9 Apr ran from sunset 18:57 Mon to sunrise 06:39, 11 h 42 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:39 to 18:57, 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, 18:57 to 06:39 Wed, 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 07:37, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 356.6° + 319.4° = 676°, one full turn and 316°. 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 12:44, 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 22:13 Mon, when the lead reached 318°; Taitila runs until 08:40.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:39 to 06:39 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Mar 12:50 Wed to 12 Apr 21:29 Thu the Sun stayed in Meena, entering Mesha at 13 Apr 18:29 Fri, 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 12 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: 14 Mar 1945, 12:50 Wed. Since then the Sun has moved 26.5° round the stars. Vikram Samvat numbers that year 2002; Shaka Samvat numbers it 1867.
