Panchang in Ipameri, Goiás, Brazil Fri 27 Mar 2048

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:51 on Fri 27 Mar to 03:32 on Sat 28 Mar, so only Friday’s pradosha (18:17–20:41) 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, 06:18 here. Dwadashi ended at 04:51, before it. Trayodashi ends at 03:32 Sat, when the lead reaches 156°. The lead passed 0° at the new moon of 14 Mar, so the Moon is waxing: Shukla paksha.

The night of Thu 26 Mar ran from sunset 18:18 Thu to sunrise 06:18, 12 h 0 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 18:17, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:17 to 06:18 Sat, splits into 8 choghadiyas of 1 h 30 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 3 at 126°40′. It leaves at 16:25, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 342.9° + 127.6° = 470.5°, one full turn and 110.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 21:57, then Ganda.

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 16:17, when the lead reaches 150°; Taitila until 03:32 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:18 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Mar 11:27 Sat to 13 Apr 02:19 Mon the Sun stayed in Meena, entering Mesha at 13 Apr 16:17 Mon, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra 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 14 Mar, with the Sun in Meena, began Chaitra (Adhik). This Shukla paksha reads Chaitra (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 14 Mar 2048, 11:27 Sat. Since then the Sun has moved 12.7° round the stars. Vikram Samvat numbers that year 2105; Shaka Samvat numbers it 1970.
