Panchang in Ipameri, Goiás, Brazil Tue 14 Feb 2068

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi began at 18:44 on Tue 14 Feb, before that evening’s pradosha, and ended at 20:52 on Wed 15 Feb, partway into the next. The Nirnayasindhu takes the evening Trayodashi fills: Tue 14 Feb. 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, 06:06 here. Ekadashi ended at 16:53 Mon, before it. Dwadashi ends at 18:44, when the lead reaches 144°. The lead passed 0° at the new moon of 3 Feb, so the Moon is waxing: Shukla paksha.

The night of Mon 13 Feb ran from sunset 18:47 Mon to sunrise 06:06, 11 h 19 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:06 to 18:47, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:47 to 06:06 Wed, splits into 8 choghadiyas of 1 h 24 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 4 at 76°40′. It leaves at 08:24, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 300.7° + 78.8° = 379.5°, one full turn and 19.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 19:11, then Ayushmana.

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 ended at 05:46, when the lead reached 138°; Balava runs until 18:44.

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

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, 3 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 3 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: 15 Mar 2067, 05:29 Tue. Since then the Sun has moved 330.7° round the stars. Vikram Samvat numbers that year 2124; Shaka Samvat numbers it 1989.
