Panchang in Ipameri, Goiás, Brazil Thu 12 Mar 2082

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 23:40 on Wed 11 Mar to 20:46 on Thu 12 Mar, so it touches only Thursday’s pradosha (18:29–20:50). 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, 06:14 here. Dwadashi ended at 23:40 Wed, before it. Trayodashi ends at 20:46, when the lead reaches 156°. The lead passed 0° at the new moon of 27 Feb, so the Moon is waxing: Shukla paksha.

Sunrise here, 06:34, came before Dwadashi ended at 08:10: this day reads Dwadashi. Trayodashi ends at 05:16 Fri, before the next sunrise, so no day here reads Trayodashi: it is kshaya.

The night of Wed 11 Mar ran from sunset 18:30 Wed to sunrise 06:14, 11 h 44 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:14 to 18:29, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:29 to 06:15 Fri, splits into 8 choghadiyas of 1 h 28 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 3 at 113°20′. It leaves at 14:33, for Magha.

Add the Sun's and the Moon's places among the stars: 327.2° + 114.9° = 442.1°, one full turn and 82.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 23:19, then Dhriti.

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 10:17, when the lead reaches 150°; Taitila until 20:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:14 to 06:15 Fri, so the hours after midnight still belong to Guruwara.

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: Kumbha gives Phalguna. The Sun enters Meena on 15 Mar, inside the month. The next new moon, 29 Mar, finds it in Meena and begins Chaitra.

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 27 Feb, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 2081, 05:16 Wed. Since then the Sun has moved 332° round the stars. Vikram Samvat numbers that year 2138; Shaka Samvat numbers it 2003.
