Panchang in Pāthardi, Maharashtra Sun 3 Oct 1982

Purnima follows the tithi at sunrise. Purnima runs from 07:19 on Sat 2 Oct to 06:38 on Sun 3 Oct, so it holds sunrise only on Sun 3 Oct, at 06:20. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Pāthardi

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 168°–180° is the 15th, Shukla Purnima. A day takes the tithi in force at its sunrise, 06:20 here. Chaturdashi ended at 07:19 Sat, before it. Purnima ends at 06:38, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:38 and ended at 05:28 Mon, between the sunrises of 06:20 and 06:20 Mon. Sunday reads Purnima and Monday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Sat 2 Oct ran from sunset 18:17 Sat to sunrise 06:20, 12 h 3 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:20 to 18:16, 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, 18:16 to 06:20 Mon, 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 4 at 343°20′. It leaves at 08:01, for Revati.

Add the Sun's and the Moon's places among the stars: 165.9° + 345.7° = 511.6°, one full turn and 151.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 20:12, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Purnima is Vishti and the second Bava. Vishti ended at 19:03 Sat, when the lead reached 174°; Bava runs until 06:38.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:20 to 06:20 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Sep 17:39 Fri to 17 Oct 05:34 Sun the Sun stayed in Kanya, entering Tula at 17 Oct 13:16 Sun, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina 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 17 Sep, with the Sun in Kanya, began Ashwina (Adhik). This Shukla paksha reads Ashwina (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1982, 15:47 Thu. Since then the Sun has moved 185.1° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
