Panchang in Sevan, Gegharkunik, Armenia Sat 13 Mar 2055

Purnima follows the tithi at sunrise. Purnima runs from 16:46 on Fri 12 Mar to 12:57 on Sat 13 Mar, so it holds sunrise only on Sat 13 Mar, at 07:15. 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, 07:15 here. Chaturdashi ended at 16:46 Fri, before it. Purnima ends at 12:57, when the lead reaches 180°. The lead passed 0° at the new moon of 26 Feb, so the Moon is waxing: Shukla paksha.

The night of Fri 12 Mar ran from sunset 19:03 Fri to sunrise 07:15, 12 h 12 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:15 to 19:04, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:04 to 07:13 Sun, splits into 8 choghadiyas of 1 h 31 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 4 at 143°20′. It leaves at 10:39, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 327.9° + 144.5° = 472.4°, one full turn and 112.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 18:27, then Ganda.

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 ended at 02:52, when the lead reached 174°; Bava runs until 12:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:15 to 07:13 Sun, so the hours after midnight still belong to Shaniwara.

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: Kumbha gives Phalguna. The Sun enters Meena on 15 Mar, inside the month. The next new moon, 28 Mar, finds it in Meena and begins Chaitra.

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 26 Feb, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 2054, 08:32 Wed. Since then the Sun has moved 333.9° round the stars. Vikram Samvat numbers that year 2111; Shaka Samvat numbers it 1976.
