Panchang in Ipameri, Goiás, Brazil Sun 3 Jul 2039

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 09:25 on Sun 3 Jul to 06:01 on Mon 4 Jul, so only Sunday’s pradosha (17:49–20:24) 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, 06:44 here. Ekadashi ended at 12:35 Sat, before it. Dwadashi ends at 09:25, when the lead reaches 144°. The lead passed 0° at the new moon of 21 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 09:25 and ended at 06:01 Mon, between the sunrises of 06:44 and 06:44 Mon. Sunday reads Dwadashi and Monday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Sat 2 Jul ran from sunset 17:49 Sat to sunrise 06:44, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:44 to 17:49, 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, 17:49 to 06:44 Mon, 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 2 at 216°40′. It leaves at 18:27, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 77° + 219.4° = 296.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 22:21, then Shukla.

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 23:02 Sat, when the lead reached 138°; Balava runs until 09:25.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:44 to 06:44 Mon, so the hours after midnight still belong to Raviwara.

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: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 21 Jul, finds it in Karka and begins Shravana.

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, began Ashadha. This Shukla paksha reads Ashadha 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 97.5° round the stars. Vikram Samvat numbers that year 2096; Shaka Samvat numbers it 1961.
