Panchang in Ipameri, Goiás, Brazil Sat 22 Feb 2070

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 02:54 on Sat 22 Feb to 01:24 on Sun 23 Feb, so only Saturday’s pradosha (18:42–20:59) 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, 06:09 here. Dwadashi ended at 02:54, before it. Trayodashi ends at 01:24 Sun, when the lead reaches 156°. The lead passed 0° at the new moon of 10 Feb, so the Moon is waxing: Shukla paksha.

The night of Fri 21 Feb ran from sunset 18:42 Fri to sunrise 06:09, 11 h 27 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:09 to 18:42, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:42 to 06:10 Sun, splits into 8 choghadiyas of 1 h 26 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 1 at 93°20′. It leaves at 02:29 Sun, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 309.2° + 95° = 404.2°, one full turn and 44.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 20:54, then Shobhana.

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 14:07, when the lead reaches 150°; Taitila until 01:24 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:09 to 06:10 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 12 Mar, finds it in Kumbha and begins Phalguna.

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 10 Feb, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2069, 22:14 Fri. Since then the Sun has moved 331° round the stars. Vikram Samvat numbers that year 2126; Shaka Samvat numbers it 1991.
