Panchang in Ipameri, Goiás, Brazil Wed 19 May 2077

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:55 on Wed 19 May to 04:15 on Thu 20 May, so only Wednesday’s pradosha (17:46–20:19) 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, 06:32 here. Ekadashi ended at 09:40 Tue, before it. Dwadashi ends at 06:55, when the lead reaches 324°. The lead passed 180° at the full moon of 7 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:55 and ended at 04:15 Thu, between the sunrises of 06:32 and 06:32 Thu. Wednesday reads Dwadashi and Thursday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Tue 18 May ran from sunset 17:46 Tue to sunrise 06:32, 12 h 46 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:32 to 17:46, splits into 8 choghadiyas of 1 h 24 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 06:32 Thu, splits into 8 choghadiyas of 1 h 35 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 09:59, for Ashwini.

Add the Sun's and the Moon's places among the stars: 34.1° + 357.9° = 392°, one full turn and 32°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 18:53, then Saubhagya.

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 20:17 Tue, when the lead reached 318°; Taitila runs until 06:55.

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

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 21 May, finds it in Vrishabha and begins Jyeshtha.

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 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2077, 05:25 Wed. Since then the Sun has moved 54.7° round the stars. Vikram Samvat numbers that year 2134; Shaka Samvat numbers it 1999.
