Panchang in Sevan, Gegharkunik, Armenia Sat 25 Feb 1956

Purnima follows the tithi at sunrise. Purnima begins at 07:31 on Sat 25 Feb, after that sunrise, and ends at 04:41 on Sun 26 Feb, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Sat 25 Feb. 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: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:41 here. Trayodashi ended at 10:32 Fri, before it. Chaturdashi ends at 07:31, when the lead reaches 168°. The lead passed 0° at the new moon of 12 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 07:31 and ended at 04:41 Sun, between the sunrises of 06:41 and 06:40 Sun. Saturday reads Chaturdashi and Sunday reads Pratipada: Purnima is a kshaya tithi here.

The night of Fri 24 Feb ran from sunset 17:44 Fri to sunrise 06:41, 12 h 57 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 17:45, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:45 to 06:40 Sun, splits into 8 choghadiyas of 1 h 36 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 07:01, for Magha.

Add the Sun's and the Moon's places among the stars: 312.3° + 119.8° = 432.1°, one full turn and 72.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 18:50, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 21:01 Fri, when the lead reached 162°; Vanija runs until 07:31.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:40 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 12 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 12 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: 24 Mar 1955, 06:42 Thu. Since then the Sun has moved 332.8° round the stars. Vikram Samvat numbers that year 2012; Shaka Samvat numbers it 1877.
