Panchang in Codcod, Western Visayas, Philippines Fri 11 Dec 2037

Vivah Panchami follows the tithi at sunrise. Panchami runs from 04:35 on Fri 11 Dec to 05:36 on Sat 12 Dec, so it holds sunrise only on Fri 11 Dec, at 05:54. 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, 05:54 here. Chaturthi ended at 04:35, before it. Panchami ends at 05:36 Sat, when the lead reaches 60°. The lead passed 0° at the new moon of 7 Dec, so the Moon is waxing: Shukla paksha.

The night of Thu 10 Dec ran from sunset 17:25 Thu 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 Sat, 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 2 at 283°20′. It leaves at 00:49 Sat, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 234.8° + 283.4° = 518.2°, one full turn and 158.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 08:59, then Vyaghata.

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 runs until 17:00, when the lead reaches 54°; Balava until 05:36 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:54 to 05:55 Sat, so the hours after midnight still belong to Shukrawara.

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, 5 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 7 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: 17 Mar 2037, 07:36 Tue. Since then the Sun has moved 262.5° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
