Panchang in Ipameri, Goiás, Brazil Wed 9 Oct 1963

Ahoi Ashtami’s puja is done in pradosha, the 3 muhurtas after sunset. Ashtami runs from 05:06 on Wed 9 Oct to 03:57 on Thu 10 Oct, so only Wednesday’s pradosha (18:11–20:30) falls within it. No text giving Ahoi Ashtami’s time was found; pradosha is Tithika’s convention.

Ahoi Ashtami: every date in Ipameri

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, 05:49 here. Saptami ended at 05:06, before it. Ashtami ends at 03:57 Thu, when the lead reaches 276°. The lead passed 180° at the full moon of 3 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

The night of Tue 8 Oct ran from sunset 18:11 Tue to sunrise 05:49, 11 h 38 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:49 to 18:11, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:11 to 05:48 Thu, splits into 8 choghadiyas of 1 h 27 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 3 at 73°20′. It leaves at 12:10, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 172° + 76.4° = 248.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 13:56, then Shiva.

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 16:27, when the lead reaches 270°; Kaulava until 03:57 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:49 to 05:48 Thu, so the hours after midnight still belong to Budhawara.

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, 17 Oct, 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 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: 25 Mar 1963, 09:09 Mon. Since then the Sun has moved 191.2° round the stars. Vikram Samvat numbers that year 2020; Shaka Samvat numbers it 1885.
