Panchang in Ipameri, Goiás, Brazil Sat 18 Jun 2039

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:44 on Sat 18 Jun to 09:18 on Sun 19 Jun, so only Saturday’s pradosha (17:46–20:21) 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, 06:41 here. Ekadashi ended at 04:18 Fri, before it. Dwadashi ends at 06:44, when the lead reaches 324°. The lead passed 180° at the full moon of 6 Jun, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Dwadashi began at 04:18 Fri, before sunrise at 06:41 Fri, and ends at 06:44, after the next sunrise at 06:41. Both days read Dwadashi: it is a vriddhi tithi here.

The night of Fri 17 Jun ran from sunset 17:45 Fri to sunrise 06:41, 12 h 56 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 17:46, 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, 17:46 to 06:42 Sun, splits into 8 choghadiyas of 1 h 37 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 4 at 23°20′. It leaves at 06:46, for Krittika.

Add the Sun's and the Moon's places among the stars: 62.6° + 26.6° = 89.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 14:20, then Dhriti.

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 17:29 Fri, when the lead reached 318°; Taitila runs until 06:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:42 Sun, so the hours after midnight still belong to Shaniwara.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 21 Jun, finds it in Mithuna and begins Ashadha.

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 21 Jun, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

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 83.1° round the stars. Vikram Samvat numbers that year 2096; Shaka Samvat numbers it 1961.
