Panchang in Ipameri, Goiás, Brazil Mon 29 Aug 2050

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 17:28 on Mon 29 Aug to 14:08 on Tue 30 Aug, so only Monday’s pradosha (18:05–20:32) 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: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 06:22 here. Ekadashi ended at 20:15 Sun, before it. Dwadashi ends at 17:28, when the lead reaches 144°. The lead passed 0° at the new moon of 17 Aug, so the Moon is waxing: Shukla paksha.

The night of Sun 28 Aug ran from sunset 18:05 Sun to sunrise 06:22, 12 h 17 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:22 to 18:05, 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, 18:05 to 06:21 Tue, 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 Ashadha spans 266°40′–280°00′; the Moon entered its pada 1 at 266°40′. It leaves at 23:44, for Shravana.

Add the Sun's and the Moon's places among the stars: 131.7° + 269.4° = 401.1°, one full turn and 41.1°. 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 01:09 Tue, then Shobhana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava runs until 06:56, when the lead reaches 138°; Balava until 17:28.

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

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Aug 08:47 Wed to 16 Sep 00:49 Fri the Sun stayed in Simha, entering Kanya at 17 Sep 03:03 Sat, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada itself.

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 17 Aug, with the Sun in Simha, began Bhadrapada (Adhik). This Shukla paksha reads Bhadrapada (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2050, 21:41 Tue. Since then the Sun has moved 153.7° round the stars. Vikram Samvat numbers that year 2107; Shaka Samvat numbers it 1972.
