Panchang in Mapleton, Utah, United States Mon 18 Oct 2032

Purnima follows the tithi at sunrise. Purnima runs from 15:56 on Sun 17 Oct to 12:58 on Mon 18 Oct, so it holds sunrise only on Mon 18 Oct, at 07:40. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Mapleton

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, 07:40 here. Chaturdashi ended at 15:56 Sun, before it. Purnima ends at 12:58, when the lead reaches 180°. The lead passed 0° at the new moon of 4 Oct, so the Moon is waxing: Shukla paksha.

The night of Sun 17 Oct ran from sunset 18:42 Sun to sunrise 07:40, 12 h 58 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:40 to 18:41, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:41 to 07:41 Tue, splits into 8 choghadiyas of 1 h 37 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 10:17, for Ashwini.

Add the Sun's and the Moon's places among the stars: 181.4° + 358.4° = 539.8°, one full turn and 179.8°. 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 18:12, 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 ended at 02:25, when the lead reached 174°; Bava runs until 12:58.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:40 to 07:41 Tue, so the hours after midnight still belong to Somawara.

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 16 Oct, inside the month. The next new moon, 2 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 4 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: 9 Apr 2032, 20:39 Fri. Since then the Sun has moved 184.9° round the stars. Vikram Samvat numbers that year 2089; Shaka Samvat numbers it 1954.
