Panchang in Pāthardi, Maharashtra Tue 22 Aug 1972

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 01:55 on Tue 22 Aug to 01:53 on Wed 23 Aug, so only Tuesday’s pradosha (18:52–21:08) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Pāthardi

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, 06:11 here. Dwadashi ended at 01:55, before it. Trayodashi ends at 01:53 Wed, when the lead reaches 156°. The lead passed 0° at the new moon of 9 Aug, so the Moon is waxing: Shukla paksha.

The night of Mon 21 Aug ran from sunset 18:52 Mon to sunrise 06:11, 11 h 19 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:11 to 18:52, 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, 18:52 to 06:12 Wed, splits into 8 choghadiyas of 1 h 25 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 2 at 270°. It leaves at 21:37, for Shravana.

Add the Sun's and the Moon's places among the stars: 125.5° + 271.7° = 397.2°, one full turn and 37.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 11:02, then Saubhagya.

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 13:59, when the lead reaches 150°; Taitila until 01:53 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:11 to 06:12 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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 7 Sep, finds it in Simha and begins Bhadrapada.

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 9 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1972, 17:04 Wed. Since then the Sun has moved 154° round the stars. Vikram Samvat numbers that year 2029; Shaka Samvat numbers it 1894.
