Panchang in Ipameri, Goiás, Brazil Tue 16 Nov 1926

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 20:54 on Tue 16 Nov to 18:10 on Wed 17 Nov, between the two evenings’ pradosha, touching neither. The Nirnayasindhu then takes the earlier day: Tue 16 Nov. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 05:29 here. Ekadashi ended at 23:41 Mon, before it. Dwadashi ends at 20:54, when the lead reaches 144°. The lead passed 0° at the new moon of 5 Nov, so the Moon is waxing: Shukla paksha.

Sunrise here, 06:43, came before Ekadashi ended at 08:11: this day reads Ekadashi. Dwadashi ends at 05:24 Wed, before the next sunrise, so no day here reads Dwadashi: it is kshaya.

Sunrise here, 05:29, came after Ekadashi ended at 23:41 Mon: this day reads Dwadashi.

The night of Mon 15 Nov ran from sunset 18:25 Mon to sunrise 05:29, 11 h 4 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:29 to 18:26, 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, 18:26 to 05:28 Wed, 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 4 at 343°20′. It leaves at 07:07, for Revati.

Add the Sun's and the Moon's places among the stars: 210.4° + 345.7° = 556.1°, one full turn and 196.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 11:31, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava runs until 10:18, when the lead reaches 138°; Balava until 20:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:29 to 05:28 Wed, so the hours after midnight still belong to Mangalawara.

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: Tula gives Kartika. The Sun enters Vrishchika on 15 Nov, inside the month. The next new moon, 5 Dec, finds it in Vrishchika and begins Margashirsha.

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 5 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 1926, 09:56 Mon. Since then the Sun has moved 211.4° round the stars. Vikram Samvat numbers that year 1983; Shaka Samvat numbers it 1848.
