Panchang in Sofia, Sofia-Capital, Bulgaria Tue 1 Aug 2023

Purnima follows the tithi at sunrise. Purnima runs from 01:22 on Tue 1 Aug to 21:31 on Tue 1 Aug, so it holds sunrise only on Tue 1 Aug, at 06:17. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Sofia

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, 06:17 here. Chaturdashi ended at 01:22, before it. Purnima ends at 21:31, 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 20:48 Mon to sunrise 06:17, 9 h 29 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:17 to 20:47, 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, 20:47 to 06:19 Wed, 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 3 at 273°20′. It leaves at 13:33, for Shravana.

Add the Sun's and the Moon's places among the stars: 104.5° + 275.4° = 379.9°, one full turn and 19.9°. 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 16:22, 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 11:28, when the lead reaches 174°; Bava until 21:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:17 to 06:19 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 21:31 Mon to 16 Aug 12:38 Wed the Sun stayed in Karka, entering Simha at 17 Aug 11:02 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, 19:23 Tue. Since then the Sun has moved 127.9° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
