Panchang in Sevan, Gegharkunik, Armenia Tue 12 Oct 1937

Durga Ashtami follows the tithi at sunrise. Ashtami holds both sunrises, 06:07 on Tue 12 Oct and 06:08 on Wed 13 Oct. Over two sunrises the Nirnayasindhu takes the first: Tue 12 Oct. No text giving Durga Ashtami’s time was found; sunrise is Tithika’s convention.

Durga Ashtami: 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, 06:07 here. Saptami ended at 05:43, before it. Ashtami ends at 07:41 Wed, when the lead reaches 96°. The lead passed 0° at the new moon of 4 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ashtami began at 05:43, before sunrise at 06:07, and ends at 07:41 Wed, after the next sunrise at 06:08 Wed. Both days read Ashtami: it is a vriddhi tithi here.

The night of Mon 11 Oct ran from sunset 17:27 Mon to sunrise 06:07, 12 h 40 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:07 to 17:25, 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, 17:25 to 06:08 Wed, splits into 8 choghadiyas of 1 h 35 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′. Purva Ashadha spans 253°20′–266°40′; the Moon entered its pada 2 at 256°40′. It leaves at 20:17, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 175.4° + 259.6° = 435°, one full turn and 75°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 15:27, then Sukarma.

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 runs until 18:47, when the lead reaches 90°; Bava until 07:41 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:07 to 06:08 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 16 Oct, inside the month. The next new moon, 3 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 4 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: 11 Apr 1937, 08:09 Sun. Since then the Sun has moved 177.5° round the stars. Vikram Samvat numbers that year 1994; Shaka Samvat numbers it 1859.
