Panchang in Sevan, Gegharkunik, Armenia Sat 29 Apr 2056

Purnima follows the tithi at sunrise. Purnima runs from 02:29 on Sat 29 Apr to 22:31 on Sat 29 Apr, so it holds sunrise only on Sat 29 Apr, at 06:01. 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, 06:01 here. Chaturdashi ended at 02:29, before it. Purnima ends at 22:31, when the lead reaches 180°. The lead passed 0° at the new moon of 15 Apr, so the Moon is waxing: Shukla paksha.

The night of Fri 28 Apr ran from sunset 19:53 Fri to sunrise 06:01, 10 h 8 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:01 to 19:54, splits into 8 choghadiyas of 1 h 44 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:54 to 05:59 Sun, splits into 8 choghadiyas of 1 h 15 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 4 at 183°20′. It leaves at 08:39, for Swati.

Add the Sun's and the Moon's places among the stars: 14.9° + 185° = 199.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 06:15, then Siddhi.

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 12:30, when the lead reaches 174°; Bava until 22:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:01 to 05:59 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Apr 03:50 Sat to 14 May 20:06 Sun the Sun stayed in Mesha, entering Vrishabha at 14 May 21:13 Sun, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 Apr, with the Sun in Mesha, began Vaishakha (Adhik). This Shukla paksha reads Vaishakha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2056, 10:52 Thu. Since then the Sun has moved 43.1° round the stars. Vikram Samvat numbers that year 2113; Shaka Samvat numbers it 1978.
