Panchang in Ipameri, Goiás, Brazil Thu 29 Sep 2039

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:19 on Thu 29 Sep to 05:16 on Fri 30 Sep, so only Thursday’s pradosha (18:09–20:31) falls within it. 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, 05:56 here. Ekadashi ended at 07:39 Wed, before it. Dwadashi ends at 06:19, when the lead reaches 144°. The lead passed 0° at the new moon of 18 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:19 and ended at 05:16 Fri, between the sunrises of 05:56 and 05:55 Fri. Thursday reads Dwadashi and Friday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Wed 28 Sep ran from sunset 18:09 Wed to sunrise 05:56, 11 h 47 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:56 to 18:09, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:09 to 05:55 Fri, splits into 8 choghadiyas of 1 h 28 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 08:01, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 161.7° + 305.5° = 467.2°, one full turn and 107.2°. 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 03:09 Fri, 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 ended at 18:57 Wed, when the lead reached 138°; Balava runs until 06:19.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:56 to 05:55 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Sep 05:23 Sun to 17 Oct 16:09 Mon the Sun stayed in Kanya, entering Tula at 17 Oct 19:25 Mon, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina itself.

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 18 Sep, with the Sun in Kanya, began Ashwina (Adhik). This Shukla paksha reads Ashwina (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2039, 14:59 Thu. Since then the Sun has moved 182.2° round the stars. Vikram Samvat numbers that year 2096; Shaka Samvat numbers it 1961.
