Panchang in Ipameri, Goiás, Brazil Sun 21 Oct 1928

Durga Ashtami follows the tithi at sunrise. Ashtami holds both sunrises, 05:40 on Sun 21 Oct and 05:39 on Mon 22 Oct. Over two sunrises the Nirnayasindhu takes the first: Sun 21 Oct. No text giving Durga Ashtami’s time was found; sunrise is Tithika’s convention.

Durga Ashtami: every date in Ipameri

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, 05:40 here. Saptami ended at 05:17, before it. Ashtami ends at 06:43 Mon, when the lead reaches 96°. The lead passed 0° at the new moon of 13 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ashtami began at 05:17, before sunrise at 05:40, and ends at 06:43 Mon, after the next sunrise at 05:39 Mon. Both days read Ashtami: it is a vriddhi tithi here.

The night of Sat 20 Oct ran from sunset 18:14 Sat to sunrise 05:40, 11 h 26 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:40 to 18:15, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:15 to 05:39 Mon, splits into 8 choghadiyas of 1 h 25 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 1 at 266°40′. It leaves at 03:05 Mon, for Shravana.

Add the Sun's and the Moon's places among the stars: 184.8° + 269° = 453.8°, one full turn and 93.8°. 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 04:44 Mon, 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 runs until 18:06, when the lead reaches 90°; Bava until 06:43 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:40 to 05:39 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 16 Oct, inside the month. The next new moon, 12 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 13 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: 21 Mar 1928, 17:29 Wed. Since then the Sun has moved 206.7° round the stars. Vikram Samvat numbers that year 1985; Shaka Samvat numbers it 1850.
