Panchang in Ipameri, Goiás, Brazil Thu 5 Jan 2073

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 05:54 on Thu 5 Jan to 05:14 on Fri 6 Jan, so only Thursday’s pradosha (18:52–21:03) 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, 05:44 here. Ekadashi ended at 06:55 Wed, before it. Dwadashi ends at 05:54, when the lead reaches 324°. The lead passed 180° at the full moon of 25 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 05:54 and ended at 05:14 Fri, between the sunrises of 05:44 and 05:44 Fri. Thursday reads Dwadashi and Friday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Wed 4 Jan ran from sunset 18:52 Wed to sunrise 05:44, 10 h 52 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:44 to 18:52, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:52 to 05:44 Fri, splits into 8 choghadiyas of 1 h 21 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 4 at 223°20′. It leaves at 09:20, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 260.7° + 224.6° = 485.3°, one full turn and 125.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 120°00′–133°20′ is the 10th, Ganda. It ends at 18:57, then Vriddhi.

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 18:22 Wed, when the lead reached 318°; Taitila runs until 05:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:44 to 05:44 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 8 Jan, finds it in Dhanu and begins Pausha.

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 8 Jan, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 2072, 17:22 Sat. Since then the Sun has moved 285.5° round the stars. Vikram Samvat numbers that year 2129; Shaka Samvat numbers it 1994.
