Panchang in Codcod, Western Visayas, Philippines Sat 24 Oct 2020

Durga Ashtami follows the tithi at sunrise. Ashtami runs from 09:27 on Fri 23 Oct to 09:29 on Sat 24 Oct, so it holds sunrise only on Sat 24 Oct, at 05:36. No text giving Durga Ashtami’s time was found; sunrise is Tithika’s convention.

Durga Ashtami: every date in Codcod

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, 05:36 here. Saptami ended at 09:27 Fri, before it. Ashtami ends at 09:29, when the lead reaches 96°. The lead passed 0° at the new moon of 17 Oct, so the Moon is waxing: Shukla paksha.

The night of Fri 23 Oct ran from sunset 17:26 Fri to sunrise 05:36, 12 h 10 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:36 to 17:25, splits into 8 choghadiyas of 1 h 28 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 05:36 Sun, splits into 8 choghadiyas of 1 h 31 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 1 at 280°. It leaves at 05:07 Sun, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 186.8° + 280.9° = 467.7°, one full turn and 107.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 03:10 Sun, then Ganda.

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 21:22 Fri, when the lead reached 90°; Bava runs until 09:29.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:36 to 05:36 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, 15 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 17 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: 24 Mar 2020, 17:28 Tue. Since then the Sun has moved 206.7° round the stars. Vikram Samvat numbers that year 2077; Shaka Samvat numbers it 1942.
