Panchang in Assiut, Asyut, Egypt Sun 31 Dec 2028

Purnima follows the tithi at sunrise. Purnima runs from 19:44 on Sat 30 Dec to 18:48 on Sun 31 Dec, so it holds sunrise only on Sun 31 Dec, at 06:44. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Assiut

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, 06:44 here. Chaturdashi ended at 19:44 Sat, before it. Purnima ends at 18:48, when the lead reaches 180°. The lead passed 0° at the new moon of 16 Dec, so the Moon is waxing: Shukla paksha.

The night of Sat 30 Dec ran from sunset 17:11 Sat to sunrise 06:44, 13 h 33 m. Cut into 15 muhurtas of 54 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:44 to 17:12, splits into 8 choghadiyas of 1 h 18 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:12 to 06:44 Mon, splits into 8 choghadiyas of 1 h 41 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 1 at 66°40′. It leaves at 01:20 Mon, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 255.8° + 69.5° = 325.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 20:04, then Indra.

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 07:20, when the lead reaches 174°; Bava until 18:48.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:44 to 06:44 Mon, so the hours after midnight still belong to Raviwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 14 Jan, finds it in Makara and begins Magha.

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 16 Dec, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 26 Mar 2028, 06:31 Sun. Since then the Sun has moved 274° round the stars. Vikram Samvat numbers that year 2085; Shaka Samvat numbers it 1950.
