Panchang in Davinópolis, Maranhão, Brazil Tue 20 Sep 2067

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 08:16 on Tue 20 Sep to 04:49 on Wed 21 Sep, so only Tuesday’s pradosha (18:05–20:28) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Davinópolis

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, 06:00 here. Ekadashi ended at 11:30 Mon, before it. Dwadashi ends at 08:16, when the lead reaches 144°. The lead passed 0° at the new moon of 8 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 08:16 and ended at 04:49 Wed, between the sunrises of 06:00 and 05:59 Wed. Tuesday reads Dwadashi and Wednesday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Mon 19 Sep ran from sunset 18:06 Mon to sunrise 06:00, 11 h 54 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:00 to 18:05, 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 night here, 18:05 to 05:59 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 1 at 293°20′. It leaves at 00:06 Wed, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 152.7° + 295.4° = 448.1°, one full turn and 88.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 13:56, then Dhriti.

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 21:56 Mon, when the lead reached 138°; Balava runs until 08:16.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:00 to 05:59 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 8 Oct, finds it in Kanya and begins Ashwina.

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 8 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada 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 182.7° round the stars. Vikram Samvat numbers that year 2124; Shaka Samvat numbers it 1989.
