Panchang in Sevan, Gegharkunik, Armenia Thu 1 Nov 2007

Ahoi Ashtami’s puja is done in pradosha, the 3 muhurtas after sunset. Ashtami runs from 13:26 on Thu 1 Nov to 13:21 on Fri 2 Nov, so only Thursday’s pradosha (17:57–20:40) falls within it. No text giving Ahoi Ashtami’s time was found; pradosha is Tithika’s convention.

Ahoi Ashtami: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 252°–264° is the 22nd, Krishna Saptami. A day takes the tithi in force at its sunrise, 07:29 here. Shashthi ended at 14:21 Wed, before it. Saptami ends at 13:26, when the lead reaches 264°. The lead passed 180° at the full moon of 26 Oct, so the Moon is waning: Krishna paksha.

The night of Wed 31 Oct ran from sunset 17:58 Wed to sunrise 07:29, 13 h 31 m. Cut into 15 muhurtas of 54 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:29 to 17:57, splits into 8 choghadiyas of 1 h 18 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:57 to 07:30 Fri, splits into 8 choghadiyas of 1 h 41 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 1 at 93°20′. It leaves at 04:11 Fri, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 194.4° + 95.3° = 289.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 13:39, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Saptami is Vishti and the second Bava. Vishti ended at 01:47, when the lead reached 258°; Bava runs until 13:26.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:29 to 07:30 Fri, so the hours after midnight still belong to Guruwara.

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, 10 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 10 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: 19 Mar 2007, 06:42 Mon. Since then the Sun has moved 220.2° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
