Panchang in Sevan, Gegharkunik, Armenia Sun 2 Sep 2096

Purnima follows the tithi at sunrise. Purnima runs from 21:13 on Sat 1 Sep to 19:37 on Sun 2 Sep, so it holds sunrise only on Sun 2 Sep, at 06:29. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Sevan

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, 06:29 here. Chaturdashi ended at 21:13 Sat, before it. Purnima ends at 19:37, when the lead reaches 180°. The lead passed 0° at the new moon of 18 Aug, so the Moon is waxing: Shukla paksha.

The night of Sat 1 Sep ran from sunset 19:30 Sat to sunrise 06:29, 10 h 59 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 19:29, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:29 to 06:30 Mon, splits into 8 choghadiyas of 1 h 22 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 1 at 306°40′. It leaves at 02:27 Mon, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 135.5° + 308.4° = 443.9°, one full turn and 83.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 21:43, then Dhriti.

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 08:29, when the lead reaches 174°; Bava until 19:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:30 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Aug 07:02 Sat to 16 Sep 19:12 Sun the Sun stayed in Simha, entering Kanya at 17 Sep 05:06 Mon, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 18 Aug, with the Sun in Simha, began Bhadrapada (Adhik). This Shukla paksha reads Bhadrapada (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 24 Mar 2096, 12:56 Sat. Since then the Sun has moved 155.9° round the stars. Vikram Samvat numbers that year 2153; Shaka Samvat numbers it 2018.
