Panchang in Sevan, Gegharkunik, Armenia Tue 12 Nov 1985

Lakshmi Puja is done in pradosha, the 3 muhurtas after sunset. Amavasya runs from 22:04 on Mon 11 Nov to 18:20 on Tue 12 Nov, so it touches only Tuesday’s pradosha (17:45–20:33). Every reading takes that day.

Lakshmi Puja muhurat: pradosha, 17:45–20:33. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 17:51 to 19:39.

Diwali: every date in Sevan

Amavasya follows the tithi at sunrise. Amavasya runs from 22:04 on Mon 11 Nov to 18:20 on Tue 12 Nov, so it holds sunrise only on Tue 12 Nov, at 07:42. 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, 07:42 here. Chaturdashi ended at 22:04 Mon, before it. Amavasya ends at 18:20, when the lead reaches 360°. The lead passed 180° at the full moon of 28 Oct, so the Moon is waning: Krishna paksha.

The night of Mon 11 Nov ran from sunset 17:46 Mon to sunrise 07:42, 13 h 56 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:42 to 17:45, 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, 17:45 to 07:43 Wed, 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 4 at 196°40′. It leaves at 08:06, for Vishakha.

Add the Sun's and the Moon's places among the stars: 206° + 199.7° = 405.7°, one full turn and 45.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 18:51, then Shobhana.

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 runs until 08:13, when the lead reaches 354°; Nagava until 18:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:42 to 07:43 Wed, so the hours after midnight still belong to Mangalawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 12 Nov, finds it in Tula and begins Kartika.

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 12 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 1985, 15:58 Thu. Since then the Sun has moved 228.8° round the stars. Vikram Samvat numbers that year 2042; Shaka Samvat numbers it 1907.
