Panchang in Ipameri, Goiás, Brazil Sun 18 Apr 2027

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 23:12 on Sat 17 Apr to 21:38 on Sun 18 Apr, so only Sunday’s pradosha (18:01–20:29) 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: 144°–156° is the 13th, Shukla Trayodashi. A day takes the tithi in force at its sunrise, 06:22 here. Dwadashi ended at 23:12 Sat, before it. Trayodashi ends at 21:38, when the lead reaches 156°. The lead passed 0° at the new moon of 6 Apr, so the Moon is waxing: Shukla paksha.

The night of Sat 17 Apr ran from sunset 18:02 Sat to sunrise 06:22, 12 h 20 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 to 18:01, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:01 to 06:22 Mon, splits into 8 choghadiyas of 1 h 32 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 2 at 150°. It leaves at 20:45, for Hasta.

Add the Sun's and the Moon's places among the stars: 3.9° + 151.7° = 155.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 13:28, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Kaulava and the second Taitila. Kaulava runs until 10:24, when the lead reaches 150°; Taitila until 21:38.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:22 to 06:22 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 6 May, finds it in Mesha and begins Vaishakha.

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 6 Apr, with the Sun in Meena, began Chaitra. This Shukla paksha reads Chaitra in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 6 Apr 2027, 20:51 Tue. Since then the Sun has moved 11.2° round the stars. Vikram Samvat numbers that year 2084; Shaka Samvat numbers it 1949.
