Panchang in Lienz, Tyrol, Austria Tue 1 Aug 2023

Purnima follows the tithi at sunrise. Purnima runs from 00:22 on Tue 1 Aug to 20:31 on Tue 1 Aug, so it holds sunrise only on Tue 1 Aug, at 05:48. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Lienz

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, 05:48 here. Chaturdashi ended at 00:22, before it. Purnima ends at 20:31, when the lead reaches 180°. The lead passed 0° at the new moon of 17 Jul, so the Moon is waxing: Shukla paksha.

The night of Mon 31 Jul ran from sunset 20:42 Mon to sunrise 05:48, 9 h 6 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:48 to 20:41, splits into 8 choghadiyas of 1 h 51 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 05:49 Wed, splits into 8 choghadiyas of 1 h 8 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 3 at 273°20′. It leaves at 12:33, for Shravana.

Add the Sun's and the Moon's places among the stars: 104.5° + 275.7° = 380.2°, one full turn and 20.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 15:22, then Ayushmana.

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 runs until 10:28, when the lead reaches 174°; Bava until 20:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:48 to 05:49 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 20:31 Mon to 16 Aug 11:38 Wed the Sun stayed in Karka, entering Simha at 17 Aug 10:02 Thu, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 17 Jul, with the Sun in Karka, began Shravana (Adhik). This Shukla paksha reads Shravana (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 2023, 18:23 Tue. Since then the Sun has moved 127.9° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
