Panchang in Cuenca, Azuay, Ecuador Sat 29 Jan 2022

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 10:07 on Sat 29 Jan to 06:59 on Sun 30 Jan, so only Saturday’s pradosha (18:36–20:57) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Cuenca

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, 06:21 here. Ekadashi ended at 13:06 Fri, before it. Dwadashi ends at 10:07, when the lead reaches 324°. The lead passed 180° at the full moon of 17 Jan, so the Moon is waning: Krishna paksha.

The night of Fri 28 Jan ran from sunset 18:36 Fri to sunrise 06:21, 11 h 45 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:21 to 18:36, 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, 18:36 to 06:22 Sun, 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 3 at 246°40′. It leaves at 16:19, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 285.4° + 247.2° = 532.6°, one full turn and 172.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 07:32, then Harshana.

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 23:38 Fri, when the lead reached 318°; Taitila runs until 10:07.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:21 to 06:22 Sun, so the hours after midnight still belong to Shaniwara.

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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 1 Feb, finds it in Makara and begins Magha.

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 1 Feb, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 2021, 21:30 Sun. Since then the Sun has moved 287.1° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
