Panchang in Myjava, Trenčín Region, Slovakia Sat 31 Oct 2020

Purnima follows the tithi at sunrise. Purnima runs from 13:16 on Fri 30 Oct to 15:49 on Sat 31 Oct, so it holds sunrise only on Sat 31 Oct, at 06:35. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Myjava

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, 06:35 here. Chaturdashi ended at 13:16 Fri, before it. Purnima ends at 15:49, when the lead reaches 180°. The lead passed 0° at the new moon of 16 Oct, so the Moon is waxing: Shukla paksha.

The night of Fri 30 Oct ran from sunset 16:32 Fri to sunrise 06:35, 14 h 3 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:35 to 16:30, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:30 to 06:36 Sun, splits into 8 choghadiyas of 1 h 45 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 3 at 6°40′. It leaves at 13:27, for Bharani.

Add the Sun's and the Moon's places among the stars: 194.1° + 9.9° = 204°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 23:55, 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 02:32, when the lead reached 174°; Bava runs until 15:49.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:35 to 06:36 Sun, so the hours after midnight still belong to Shaniwara.

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, 15 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 16 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: 24 Mar 2020, 10:28 Tue. Since then the Sun has moved 214° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
