Panchang in Sevan, Gegharkunik, Armenia Mon 20 Sep 2055

The shraddha for all ancestors is done in aparahna, the fourth fifth of the day. Amavasya runs from 10:04 on Mon 20 Sep to 06:20 on Tue 21 Sep, so only Monday’s aparahna (14:06–16:33) falls within it. No text giving Sarva Pitru Amavasya’s time was found; aparahna is Tithika’s convention.

Sarva Pitru Amavasya: every date in Sevan

Amavasya follows the tithi at sunrise. Amavasya begins at 10:04 on Mon 20 Sep, after that sunrise, and ends at 06:20 on Tue 21 Sep, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Mon 20 Sep. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:45 here. Trayodashi ended at 13:30 Sun, before it. Chaturdashi ends at 10:04, when the lead reaches 348°. The lead passed 180° at the full moon of 6 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 10:04 and ended at 06:20 Tue, between the sunrises of 06:45 and 06:46 Tue. Monday reads Chaturdashi and Tuesday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Sun 19 Sep ran from sunset 19:02 Sun to sunrise 06:45, 11 h 43 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:45 to 19:00, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:00 to 06:46 Tue, splits into 8 choghadiyas of 1 h 28 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 Phalguni spans 133°20′–146°40′; the Moon entered its pada 2 at 136°40′. It leaves at 19:36, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 152.5° + 138.6° = 291.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 10:07, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 23:50 Sun, when the lead reached 342°; Shakuni runs until 10:04.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:45 to 06:46 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 21 Sep, finds it in Kanya and begins Ashwina.

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 21 Sep, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2055, 11:01 Sun. Since then the Sun has moved 169.5° round the stars. Vikram Samvat numbers that year 2112; Shaka Samvat numbers it 1977.
