Panchang in Ipameri, Goiás, Brazil Sat 21 Nov 2009

Vivah Panchami follows the tithi at sunrise. Panchami runs from 22:31 on Fri 20 Nov to 01:04 on Sun 22 Nov, so it holds sunrise only on Sat 21 Nov, at 06:28. No text giving Vivah Panchami’s time was found; sunrise is Tithika’s convention.

Vivah Panchami: every date in Ipameri

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, 06:28 here. Chaturthi ended at 22:31 Fri, before it. Panchami ends at 01:04 Sun, when the lead reaches 60°. The lead passed 0° at the new moon of 16 Nov, so the Moon is waxing: Shukla paksha.

The night of Fri 20 Nov ran from sunset 19:28 Fri to sunrise 06:28, 11 h 0 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:28 to 19:29, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:29 to 06:28 Sun, splits into 8 choghadiyas of 1 h 22 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 1 at 266°40′. It leaves at 09:18 Sun, for Shravana.

Add the Sun's and the Moon's places among the stars: 215.2° + 266.8° = 482°, one full turn and 122°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 03:46 Sun, then Vriddhi.

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 11:45, when the lead reaches 54°; Balava until 01:04 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:28 to 06:28 Sun, so the hours after midnight still belong to Shaniwara.

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 15 Dec, inside the month. The next new moon, 16 Dec, 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 16 Nov, 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: 26 Mar 2009, 13:05 Thu. Since then the Sun has moved 233.1° round the stars. Vikram Samvat numbers that year 2066; Shaka Samvat numbers it 1931.
