Panchang in Sevan, Gegharkunik, Armenia Thu 29 Jan 1953

Purnima follows the tithi at sunrise. Purnima runs from 00:30 on Thu 29 Jan to 02:44 on Fri 30 Jan, so it holds sunrise only on Thu 29 Jan, at 07:12. 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, 07:12 here. Chaturdashi ended at 00:30, before it. Purnima ends at 02:44 Fri, when the lead reaches 180°. The lead passed 0° at the new moon of 15 Jan, so the Moon is waxing: Shukla paksha.

The night of Wed 28 Jan ran from sunset 17:12 Wed to sunrise 07:12, 14 h 0 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:12 to 17:13, 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 night here, 17:13 to 07:12 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Pushya spans 93°20′–106°40′; the Moon entered its pada 2 at 96°40′. It leaves at 02:52 Fri, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 285.8° + 96.9° = 382.7°, one full turn and 22.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 14:40, then Ayushmana.

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 13:34, when the lead reaches 174°; Bava until 02:44 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:12 to 07:12 Fri, so the hours after midnight still belong to Guruwara.

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 12 Feb, inside the month. The next new moon, 14 Feb, 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 15 Jan, 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: 25 Mar 1952, 23:12 Tue. Since then the Sun has moved 303.9° round the stars. Vikram Samvat numbers that year 2009; Shaka Samvat numbers it 1874.
