Panchang in Sevan, Gegharkunik, Armenia Sat 29 Oct 1983

Ahoi Ashtami’s puja is done in pradosha, the 3 muhurtas after sunset. Ashtami runs from 20:34 on Fri 28 Oct to 18:34 on Sat 29 Oct, touching pradosha on both evenings. The Nirnayasindhu takes the evening it holds more of: Sat 29 Oct. 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: 264°–276° is the 23rd, Krishna Ashtami. A day takes the tithi in force at its sunrise, 07:25 here. Saptami ended at 20:34 Fri, before it. Ashtami ends at 18:34, when the lead reaches 276°. The lead passed 180° at the full moon of 22 Oct, so the Moon is waning: Krishna paksha.

The night of Fri 28 Oct ran from sunset 18:02 Fri to sunrise 07:25, 13 h 23 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:25 to 18:01, splits into 8 choghadiyas of 1 h 19 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:01 to 07:26 Sun, splits into 8 choghadiyas of 1 h 40 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 3 at 100°. It leaves at 16:22, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 191.5° + 101.4° = 292.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 08:05, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Balava and the second Kaulava. Balava runs until 07:36, when the lead reaches 270°; Kaulava until 18:34.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:25 to 07:26 Sun, so the hours after midnight still belong to Shaniwara.

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, 5 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 5 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: 13 Apr 1983, 12:58 Wed. Since then the Sun has moved 192.3° round the stars. Vikram Samvat numbers that year 2040; Shaka Samvat numbers it 1905.
