Panchang in Pāthardi, Maharashtra Wed 24 Oct 2018

Purnima follows the tithi at sunrise. Purnima runs from 22:36 on Tue 23 Oct to 22:15 on Wed 24 Oct, so it holds sunrise only on Wed 24 Oct, at 06:26. 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, 06:26 here. Chaturdashi ended at 22:36 Tue, before it. Purnima ends at 22:15, when the lead reaches 180°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

The night of Tue 23 Oct ran from sunset 18:00 Tue to sunrise 06:26, 12 h 26 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:26 to 18:00, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:00 to 06:26 Thu, splits into 8 choghadiyas of 1 h 33 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 4 at 356°40′. It leaves at 09:22, for Ashwini.

Add the Sun's and the Moon's places among the stars: 186.4° + 358.4° = 544.8°, one full turn and 184.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 09:32, then Vajra.

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 runs until 10:29, when the lead reaches 174°; Bava until 22:15.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:26 to 06:26 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 7 Nov, finds it in Tula and begins Kartika.

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 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 18:41 Sat. Since then the Sun has moved 213.6° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
