Panchang in Ipameri, Goiás, Brazil Wed 5 Oct 2033

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 18:32 on Wed 5 Oct to 15:18 on Thu 6 Oct, so it touches only Wednesday’s pradosha (18:11–20:30). 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, 05:51 here. Ekadashi ended at 21:17 Tue, before it. Dwadashi ends at 18:32, when the lead reaches 144°. The lead passed 0° at the new moon of 23 Sep, so the Moon is waxing: Shukla paksha.

The night of Tue 4 Oct ran from sunset 18:10 Tue to sunrise 05:51, 11 h 41 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:51 to 18:11, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:11 to 05:50 Thu, splits into 8 choghadiyas of 1 h 27 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 4 at 303°20′. It leaves at 08:45, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 168.1° + 304.9° = 473°, one full turn and 113°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 16:36, then Ganda.

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 07:59, when the lead reaches 138°; Balava until 18:32.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:51 to 05:50 Thu, so the hours after midnight still belong to Budhawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 23 Oct, finds it in Tula and begins Kartika.

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 23 Sep, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 30 Mar 2033, 14:51 Wed. Since then the Sun has moved 182.1° round the stars. Vikram Samvat numbers that year 2090; Shaka Samvat numbers it 1955.
