Panchang in Sevan, Gegharkunik, Armenia Sun 13 Jul 2003

Guru Purnima follows the tithi at sunrise. Purnima runs from 02:50 on Sun 13 Jul to 00:21 on Mon 14 Jul, so it holds sunrise only on Sun 13 Jul, at 06:40. No text giving Guru 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, 06:40 here. Chaturdashi ended at 02:50, before it. Purnima ends at 00:21 Mon, when the lead reaches 180°. The lead passed 0° at the new moon of 29 Jun, so the Moon is waxing: Shukla paksha.

The night of Sat 12 Jul ran from sunset 21:31 Sat to sunrise 06:40, 9 h 9 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 to 21:30, splits into 8 choghadiyas of 1 h 51 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:30 to 06:40 Mon, splits into 8 choghadiyas of 1 h 8 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 Ashadha spans 253°20′–266°40′; the Moon entered its pada 1 at 253°20′. It leaves at 23:39, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 86.4° + 256.5° = 342.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 12:32, then Vaidhriti.

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 13:33, when the lead reaches 174°; Bava until 00:21 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 to 06:40 Mon, so the hours after midnight still belong to Raviwara.

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: Mithuna gives Ashadha. The Sun enters Karka on 17 Jul, inside the month. The next new moon, 29 Jul, finds it in Karka and begins Shravana.

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 29 Jun, with the Sun in Mithuna, began Ashadha. This Shukla paksha reads Ashadha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 2 Apr 2003, 00:18 Wed. Since then the Sun has moved 98.6° round the stars. Vikram Samvat numbers that year 2060; Shaka Samvat numbers it 1925.
