Panchang in Mapleton, Utah, United States Mon 26 Oct 2015

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 09:40 on Mon 26 Oct to 06:05 on Tue 27 Oct, so only Monday night’s nishitha (00:44 Tue–01:37 Tue) falls within it. No text giving Sharad Purnima’s time was found; nishitha is Tithika’s convention.

Sharad Purnima: every date in Mapleton

Purnima follows the tithi at sunrise. Purnima begins at 09:40 on Mon 26 Oct, after that sunrise, and ends at 06:05 on Tue 27 Oct, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Mon 26 Oct. 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: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 07:48 here. Trayodashi ended at 13:14 Sun, before it. Chaturdashi ends at 09:40, when the lead reaches 168°. The lead passed 0° at the new moon of 12 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 09:40 and ended at 06:05 Tue, between the sunrises of 07:48 and 07:49 Tue. Monday reads Chaturdashi and Tuesday reads Pratipada: Purnima is a kshaya tithi here.

The night of Sun 25 Oct ran from sunset 18:32 Sun to sunrise 07:48, 13 h 16 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:48 to 18:31, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:31 to 07:49 Tue, splits into 8 choghadiyas of 1 h 39 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 3 at 353°20′. It leaves at 14:42, for Ashwini.

Add the Sun's and the Moon's places among the stars: 188.7° + 355.7° = 544.4°, one full turn and 184.4°. 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 11:11, then Vajra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 23:27 Sun, when the lead reached 162°; Vanija runs until 09:40.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:48 to 07:49 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 17 Oct, inside the month. The next new moon, 11 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 12 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: 20 Mar 2015, 03:36 Fri. Since then the Sun has moved 213.3° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
