Panchang in Myjava, Trenčín Region, Slovakia Wed 28 Apr 2010

Purnima follows the tithi at sunrise. Purnima runs from 16:23 on Tue 27 Apr to 14:18 on Wed 28 Apr, so it holds sunrise only on Wed 28 Apr, at 05:35. 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, 05:35 here. Chaturdashi ended at 16:23 Tue, before it. Purnima ends at 14:18, when the lead reaches 180°. The lead passed 0° at the new moon of 14 Apr, so the Moon is waxing: Shukla paksha.

The night of Tue 27 Apr ran from sunset 19:58 Tue to sunrise 05:35, 9 h 37 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:35 to 20:00, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:00 to 05:33 Thu, splits into 8 choghadiyas of 1 h 11 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 1 at 186°40′. It leaves at 00:28 Thu, for Vishakha.

Add the Sun's and the Moon's places among the stars: 13.8° + 189° = 202.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 22:33, 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 03:18, when the lead reached 174°; Bava runs until 14:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:35 to 05:33 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 14:28 Wed to 14 May 03:04 Fri the Sun stayed in Mesha, entering Vrishabha at 15 May 00:16 Sat, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha itself.

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 14 Apr, with the Sun in Mesha, began Vaishakha (Adhik). This Shukla paksha reads Vaishakha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 2010, 22:01 Mon. Since then the Sun has moved 42.6° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
