Panchang in Codcod, Western Visayas, Philippines Wed 7 Nov 2012

Ahoi Ashtami’s puja is done in pradosha, the 3 muhurtas after sunset. Ashtami runs from 20:07 on Tue 6 Nov to 20:52 on Wed 7 Nov, so only Wednesday’s pradosha (17:21–19:49) falls within it. No text giving Ahoi Ashtami’s time was found; pradosha is Tithika’s convention.

Ahoi Ashtami: every date in Codcod

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, 05:39 here. Saptami ended at 20:07 Tue, before it. Ashtami ends at 20:52, when the lead reaches 276°. The lead passed 180° at the full moon of 30 Oct, so the Moon is waning: Krishna paksha.

The night of Tue 6 Nov ran from sunset 17:22 Tue to sunrise 05:39, 12 h 17 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:39 to 17:21, 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 night here, 17:21 to 05:40 Thu, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 01:34 Thu, for Magha.

Add the Sun's and the Moon's places among the stars: 200.8° + 109.4° = 310.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 22:40, then Brahma.

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 08:35, when the lead reaches 270°; Kaulava until 20:52.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:39 to 05:40 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, 14 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 14 Nov, 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: 22 Mar 2012, 22:37 Thu. Since then the Sun has moved 222.5° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
