Panchang in Ipameri, Goiás, Brazil Wed 10 Jun 2037

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 15:26 on Wed 10 Jun to 15:35 on Thu 11 Jun, so only Wednesday’s pradosha (17:45–20:20) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 06:39 here. Ekadashi ended at 14:38 Tue, before it. Dwadashi ends at 15:26, when the lead reaches 324°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

The night of Tue 9 Jun ran from sunset 17:44 Tue to sunrise 06:39, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:39 to 17:45, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:45 to 06:40 Thu, splits into 8 choghadiyas of 1 h 36 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 04:14 Thu, for Krittika.

Add the Sun's and the Moon's places among the stars: 55.5° + 15.2° = 70.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 23:00, then Sukarma.

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 ended at 03:07, when the lead reached 318°; Taitila runs until 15:26.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:39 to 06:40 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 15 May 02:54 Fri to 13 Jun 14:10 Sat the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 00:02 Mon, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 13 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2037, 20:36 Mon. Since then the Sun has moved 83.2° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
