Panchang in Myjava, Trenčín Region, Slovakia Sun 28 Oct 2012

Sharad Purnima’s night centres on nishitha, the midnight muhurta. Purnima runs from 18:47 on Sun 28 Oct to 20:49 on Mon 29 Oct, so only Sunday night’s nishitha (23:05–00:01 Mon) falls within it. No text giving Sharad Purnima’s time was found; nishitha is Tithika’s convention.

Sharad Purnima: every date in Myjava

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, 06:30 here. Trayodashi ended at 18:07 Sat, before it. Chaturdashi ends at 18:47, when the lead reaches 168°. The lead passed 0° at the new moon of 15 Oct, so the Moon is waxing: Shukla paksha.

The night of Sat 27 Oct ran from sunset 17:37 Sat to sunrise 06:30, 13 h 53 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:30 to 16:35, splits into 8 choghadiyas of 1 h 15 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:35 to 06:32 Mon, splits into 8 choghadiyas of 1 h 44 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 19:25, for Ashwini.

Add the Sun's and the Moon's places among the stars: 191.2° + 353.4° = 544.6°, one full turn and 184.6°. 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 10:14, 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 05:54, when the lead reached 162°; Vanija runs until 18:47.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:30 to 06:32 Mon, so the hours after midnight still belong to Raviwara.

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, 13 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 15 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: 22 Mar 2012, 15:37 Thu. Since then the Sun has moved 212.9° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
