Panchang in Sevan, Gegharkunik, Armenia Sun 20 Oct 1996

Durga Ashtami follows the tithi at sunrise. Ashtami runs from 11:11 on Sat 19 Oct to 09:04 on Sun 20 Oct, so it holds sunrise only on Sun 20 Oct, at 07:16. No text giving Durga Ashtami’s time was found; sunrise is Tithika’s convention.

Durga Ashtami: every date in Sevan

Maha Navami follows the tithi at sunrise. Navami begins at 09:04 on Sun 20 Oct, after that sunrise, and ends at 06:49 on Mon 21 Oct, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Sun 20 Oct. No text giving Maha Navami’s time was found; sunrise is Tithika’s convention.

Maha Navami: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 84°–96° is the 8th, Shukla Ashtami. A day takes the tithi in force at its sunrise, 07:16 here. Saptami ended at 11:11 Sat, before it. Ashtami ends at 09:04, when the lead reaches 96°. The lead passed 0° at the new moon of 12 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Navami began at 09:04 and ended at 06:49 Mon, between the sunrises of 07:16 and 07:17 Mon. Sunday reads Ashtami and Monday reads Dashami: Navami is a kshaya tithi here.

The night of Sat 19 Oct ran from sunset 18:14 Sat to sunrise 07:16, 13 h 2 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:16 to 18:12, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:12 to 07:17 Mon, splits into 8 choghadiyas of 1 h 38 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 4 at 276°40′. It leaves at 10:17, for Shravana.

Add the Sun's and the Moon's places among the stars: 183.2° + 278.2° = 461.4°, one full turn and 101.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 15:34, then Shula.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ashtami is Vishti and the second Bava. Vishti ended at 22:09 Sat, when the lead reached 90°; Bava runs until 09:04.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:16 to 07:17 Mon, so the hours after midnight still belong to Raviwara.

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, 11 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 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 1996, 14:44 Tue. Since then the Sun has moved 207.9° round the stars. Vikram Samvat numbers that year 2053; Shaka Samvat numbers it 1918.
