Panchang in Davinópolis, Maranhão, Brazil Wed 3 Oct 2040

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 23:51 on Tue 2 Oct to 01:13 on Thu 4 Oct, so only Wednesday’s pradosha (18:03–20:25) 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: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 05:53 here. Dwadashi ended at 23:51 Tue, before it. Trayodashi ends at 01:13 Thu, when the lead reaches 336°. The lead passed 180° at the full moon of 20 Sep, so the Moon is waning: Krishna paksha.

The night of Tue 2 Oct ran from sunset 18:03 Tue to sunrise 05:53, 11 h 50 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:53 to 18:03, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:03 to 05:53 Thu, splits into 8 choghadiyas of 1 h 28 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 4 at 130°. It leaves at 06:12, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 166.3° + 133.2° = 299.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 18:47, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja runs until 12:36, when the lead reaches 330°; Vanija until 01:13 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:53 to 05:53 Thu, so the hours after midnight still belong to Budhawara.

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 16 Sep, inside the month. The next new moon, 6 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 6 Oct, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 2040, 11:00 Wed. Since then the Sun has moved 168.4° round the stars. Vikram Samvat numbers that year 2097; Shaka Samvat numbers it 1962.
