Panchang in Sevan, Gegharkunik, Armenia Fri 14 Oct 1966

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 07:51 on Fri 14 Oct to 04:32 on Sat 15 Oct, so it touches only Friday’s pratahkala (07:09–09:23).

Sharad Navratri: every date in Sevan

Amavasya follows the tithi at sunrise. Amavasya runs from 11:24 on Thu 13 Oct to 07:51 on Fri 14 Oct, so it holds sunrise only on Fri 14 Oct, at 07:09. 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: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 07:09 here. Chaturdashi ended at 11:24 Thu, before it. Amavasya ends at 07:51, when the lead reaches 360°. The lead passed 180° at the full moon of 29 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 07:51 and ended at 04:32 Sat, between the sunrises of 07:09 and 07:10 Sat. Friday reads Amavasya and Saturday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Thu 13 Oct ran from sunset 18:24 Thu to sunrise 07:09, 12 h 45 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:09 to 18:22, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:22 to 07:10 Sat, 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 1 at 173°20′. It leaves at 23:26, for Swati.

Add the Sun's and the Moon's places among the stars: 176.9° + 176.5° = 353.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 16:58, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada ended at 21:36 Thu, when the lead reached 354°; Nagava runs until 07:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:09 to 07:10 Sat, so the hours after midnight still belong to Shukrawara.

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 16 Sep, inside the month. The next new moon, 14 Oct, 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 14 Oct, 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: 22 Mar 1966, 08:46 Tue. Since then the Sun has moved 199.2° round the stars. Vikram Samvat numbers that year 2023; Shaka Samvat numbers it 1888.
