Panchang in Ipameri, Goiás, Brazil Wed 13 Aug 1947

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 19:00 on Wed 13 Aug to 15:30 on Thu 14 Aug, so it touches only Wednesday’s pradosha (18:01–20:32). 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 06:33 here. Ekadashi ended at 22:12 Tue, before it. Dwadashi ends at 19:00, when the lead reaches 324°. The lead passed 180° at the full moon of 1 Aug, so the Moon is waning: Krishna paksha.

Sunrise here, 05:48, came before Ekadashi ended at 06:42: this day reads Ekadashi. Dwadashi ends at 03:30 Thu, before the next sunrise, so no day here reads Dwadashi: it is kshaya.

Sunrise here, 06:33, came after Ekadashi ended at 22:12 Tue: this day reads Dwadashi.

The night of Tue 12 Aug ran from sunset 18:01 Tue to sunrise 06:33, 12 h 32 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:33 to 18:01, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:01 to 06:32 Thu, splits into 8 choghadiyas of 1 h 33 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 3 at 73°20′. It leaves at 17:08, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 116.7° + 73.5° = 190.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 21:31, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava runs until 08:39, when the lead reaches 318°; Taitila until 19:00.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:33 to 06:32 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 01:15 Fri to 16 Aug 08:12 Sat the Sun stayed in Karka, entering Simha at 16 Aug 17:42 Sat, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 16 Aug, with the Sun in Karka, begins Shravana (Adhik). Until then this Krishna paksha reads Shravana (Adhik) here, and Shravana (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 1947, 13:34 Sat. Since then the Sun has moved 138.6° round the stars. Vikram Samvat numbers that year 2004; Shaka Samvat numbers it 1869.
