Panchang in Codcod, Western Visayas, Philippines Thu 20 Dec 2001

Vivah Panchami follows the tithi at sunrise. Panchami runs from 08:29 on Wed 19 Dec to 10:41 on Thu 20 Dec, so it holds sunrise only on Thu 20 Dec, at 05:59. No text giving Vivah Panchami’s time was found; sunrise is Tithika’s convention.

Vivah Panchami: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 48°–60° is the 5th, Shukla Panchami. A day takes the tithi in force at its sunrise, 05:59 here. Chaturthi ended at 08:29 Wed, before it. Panchami ends at 10:41, when the lead reaches 60°. The lead passed 0° at the new moon of 15 Dec, so the Moon is waxing: Shukla paksha.

The night of Wed 19 Dec ran from sunset 17:29 Wed to sunrise 05:59, 12 h 30 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:59 to 17:30, 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, 17:30 to 05:59 Fri, 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′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 3 at 300°. It leaves at 15:15, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 244.2° + 302.1° = 546.3°, one full turn and 186.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 06:45, then Vajra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Panchami is Bava and the second Balava. Bava ended at 21:32 Wed, when the lead reached 54°; Balava runs until 10:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:59 to 05:59 Fri, so the hours after midnight still belong to Guruwara.

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, 13 Jan, 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 15 Dec, 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: 25 Mar 2001, 09:21 Sun. Since then the Sun has moved 263.6° round the stars. Vikram Samvat numbers that year 2058; Shaka Samvat numbers it 1923.
