Panchang in Ipameri, Goiás, Brazil Mon 10 Dec 1934

Vivah Panchami follows the tithi at sunrise. Panchami runs from 03:41 on Mon 10 Dec to 01:07 on Tue 11 Dec, so it holds sunrise only on Mon 10 Dec, at 05:30. 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, 05:30 here. Chaturthi ended at 03:41, before it. Panchami ends at 01:07 Tue, when the lead reaches 60°. The lead passed 0° at the new moon of 6 Dec, so the Moon is waxing: Shukla paksha.

The night of Sun 9 Dec ran from sunset 18:39 Sun to sunrise 05:30, 10 h 51 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:30 to 18:40, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:40 to 05:30 Tue, splits into 8 choghadiyas of 1 h 21 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 21:32, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 234.7° + 283.7° = 518.4°, one full turn and 158.4°. 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 08:05, 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 14:23, when the lead reaches 54°; Balava until 01:07 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:30 to 05:30 Tue, so the hours after midnight still belong to Somawara.

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, 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 6 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: 15 Mar 1934, 09:08 Thu. Since then the Sun has moved 263.4° round the stars. Vikram Samvat numbers that year 1991; Shaka Samvat numbers it 1856.
