Panchang in Ipameri, Goiás, Brazil Wed 11 Jun 2064

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 17:58 on Wed 11 Jun to 18:58 on Thu 12 Jun, touching pradosha on both evenings. The Nirnayasindhu takes the evening it holds more of: Wed 11 Jun. 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, 06:40 here. Ekadashi ended at 16:26 Tue, before it. Dwadashi ends at 17:58, when the lead reaches 324°. The lead passed 180° at the full moon of 30 May, so the Moon is waning: Krishna paksha.

The night of Tue 10 Jun ran from sunset 17:45 Tue to sunrise 06:40, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 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 05:00 Thu, for Krittika.

Add the Sun's and the Moon's places among the stars: 56.5° + 15.2° = 71.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 21:41, 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 05:16, when the lead reached 318°; Taitila runs until 17:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 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 16 May 06:55 Fri to 14 Jun 19:21 Sat the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 22:06 Sat, 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 14 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: 17 Mar 2064, 22:45 Mon. Since then the Sun has moved 83° round the stars. Vikram Samvat numbers that year 2121; Shaka Samvat numbers it 1986.
