Panchang in Pāthardi, Maharashtra Sun 27 Feb 1983

Purnima follows the tithi at sunrise. Purnima runs from 17:51 on Sat 26 Feb to 14:28 on Sun 27 Feb, so it holds sunrise only on Sun 27 Feb, at 06:50. 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, 06:50 here. Chaturdashi ended at 17:51 Sat, before it. Purnima ends at 14:28, when the lead reaches 180°. The lead passed 0° at the new moon of 13 Feb, so the Moon is waxing: Shukla paksha.

The night of Sat 26 Feb ran from sunset 18:33 Sat to sunrise 06:50, 12 h 17 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:50 to 18:33, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:33 to 06:49 Mon, splits into 8 choghadiyas of 1 h 32 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 3 at 126°40′. It leaves at 12:27, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 314.3° + 129.8° = 444.1°, one full turn and 84.1°. 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 20:46, then Dhriti.

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 04:08, when the lead reached 174°; Bava runs until 14:28.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:50 to 06:49 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 13 Feb 06:01 Sun to 14 Mar 23:13 Mon the Sun stayed in Kumbha, entering Meena at 15 Mar 00:14 Tue, after the new moon. A month with no sankranti is Adhika Phalguna, before Phalguna 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 13 Feb, with the Sun in Kumbha, began Phalguna (Adhik). This Shukla paksha reads Phalguna (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 333.5° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
