Panchang in Sevan, Gegharkunik, Armenia Mon 30 Jun 2053

Purnima follows the tithi at sunrise. Purnima holds both sunrises, 05:32 on Mon 30 Jun and 05:33 on Tue 1 Jul. Over two sunrises the Nirnayasindhu takes the first: Mon 30 Jun. 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, 05:32 here. Chaturdashi ended at 03:39, before it. Purnima ends at 06:01 Tue, when the lead reaches 180°. The lead passed 0° at the new moon of 16 Jun, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 03:39, before sunrise at 05:32, and ends at 06:01 Tue, after the next sunrise at 05:33 Tue. Both days read Purnima: it is a vriddhi tithi here.

The night of Sun 29 Jun ran from sunset 20:34 Sun to sunrise 05:32, 8 h 58 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:32 to 20:34, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:34 to 05:33 Tue, splits into 8 choghadiyas of 1 h 7 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′. Mula spans 240°00′–253°20′; the Moon entered its pada 1 at 240°. It leaves at 02:23 Tue, for Purva Ashadha.

Add the Sun's and the Moon's places among the stars: 74.2° + 243° = 317.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 10:49, then Brahma.

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 16:49, when the lead reaches 174°; Bava until 06:01 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:32 to 05:33 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 Jun 14:51 Mon to 15 Jul 21:26 Tue the Sun stayed in Mithuna, entering Karka at 16 Jul 20:17 Wed, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 16 Jun, with the Sun in Mithuna, began Ashadha (Adhik). This Shukla paksha reads Ashadha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2053, 11:11 Thu. Since then the Sun has moved 98.7° round the stars. Vikram Samvat numbers that year 2110; Shaka Samvat numbers it 1975.
