Panchang in Myjava, Trenčín Region, Slovakia Fri 29 May 2037

Purnima follows the tithi at sunrise. Purnima runs from 08:03 on Thu 28 May to 06:24 on Fri 29 May, so it holds sunrise only on Fri 29 May, at 04:53. 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, 04:53 here. Chaturdashi ended at 08:03 Thu, before it. Purnima ends at 06:24, when the lead reaches 180°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

The night of Thu 28 May ran from sunset 20:40 Thu to sunrise 04:53, 8 h 13 m. Cut into 15 muhurtas of 32 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:53 to 20:41, splits into 8 choghadiyas of 1 h 58 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:41 to 04:52 Sat, splits into 8 choghadiyas of 1 h 1 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′. Anuradha spans 213°20′–226°40′; the Moon entered its pada 3 at 220°. It leaves at 11:27, for Jyeshtha.

Add the Sun's and the Moon's places among the stars: 43.7° + 222.9° = 266.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 04:56, then Siddha.

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 19:10 Thu, when the lead reached 174°; Bava runs until 06:24.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:53 to 04:52 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 07:54 Fri to 13 Jun 19:10 Sat the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 05:02 Mon, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 15 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2037, 00:36 Tue. Since then the Sun has moved 71.4° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
