Panchang in Sevan, Gegharkunik, Armenia Mon 16 Feb 2060

Purnima follows the tithi at sunrise. Purnima runs from 12:38 on Sun 15 Feb to 13:56 on Mon 16 Feb, so it holds sunrise only on Mon 16 Feb, at 07:52. 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, 07:52 here. Chaturdashi ended at 12:38 Sun, before it. Purnima ends at 13:56, when the lead reaches 180°. The lead passed 0° at the new moon of 2 Feb, so the Moon is waxing: Shukla paksha.

The night of Sun 15 Feb ran from sunset 18:34 Sun to sunrise 07:52, 13 h 18 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:52 to 18:35, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:35 to 07:51 Tue, splits into 8 choghadiyas of 1 h 39 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 4 at 116°40′. It leaves at 08:31, for Magha.

Add the Sun's and the Moon's places among the stars: 302.5° + 119.7° = 422.2°, one full turn and 62.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 15:56, then Atiganda.

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 01:14, when the lead reached 174°; Bava runs until 13:56.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:52 to 07:51 Tue, so the hours after midnight still belong to Somawara.

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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 2 Mar, finds it in Kumbha and begins Phalguna.

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 2 Feb, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 2059, 13:29 Sat. Since then the Sun has moved 304.7° round the stars. Vikram Samvat numbers that year 2116; Shaka Samvat numbers it 1981.
