Panchang in Pāthardi, Maharashtra Wed 29 Apr 1953

Purnima follows the tithi at sunrise. Purnima runs from 08:41 on Tue 28 Apr to 09:50 on Wed 29 Apr, so it holds sunrise only on Wed 29 Apr, at 06:02. 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, 06:02 here. Chaturdashi ended at 08:41 Tue, before it. Purnima ends at 09:50, when the lead reaches 180°. The lead passed 0° at the new moon of 14 Apr, so the Moon is waxing: Shukla paksha.

The night of Tue 28 Apr ran from sunset 18:50 Tue to sunrise 06:02, 11 h 12 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:02 to 18:50, splits into 8 choghadiyas of 1 h 36 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:50 to 06:01 Thu, splits into 8 choghadiyas of 1 h 23 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 3 at 193°20′. It leaves at 18:43, for Vishakha.

Add the Sun's and the Moon's places among the stars: 15.2° + 193.4° = 208.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 14:31, then Vyatipata.

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 21:19 Tue, when the lead reached 174°; Bava runs until 09:50.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:02 to 06:01 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 01:38 Tue to 13 May 10:35 Wed the Sun stayed in Mesha, entering Vrishabha at 14 May 13:11 Thu, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 14 Apr, with the Sun in Mesha, began Vaishakha (Adhik). This Shukla paksha reads Vaishakha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1953, 16:34 Sun. Since then the Sun has moved 43.8° round the stars. Vikram Samvat numbers that year 2010; Shaka Samvat numbers it 1875.
