Panchang in Ipameri, Goiás, Brazil Tue 29 Oct 1991

Ahoi Ashtami’s puja is done in pradosha, the 3 muhurtas after sunset. Ashtami runs from 18:10 on Tue 29 Oct to 16:13 on Wed 30 Oct, so only Tuesday’s pradosha (19:17–21:33) 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: 252°–264° is the 22nd, Krishna Saptami. A day takes the tithi in force at its sunrise, 06:35 here. Shashthi ended at 20:16 Mon, before it. Saptami ends at 18:10, when the lead reaches 264°. The lead passed 180° at the full moon of 23 Oct, so the Moon is waning: Krishna paksha.

The night of Mon 28 Oct ran from sunset 19:17 Mon to sunrise 06:35, 11 h 18 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:35 to 19:17, 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 night here, 19:17 to 06:35 Wed, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 3 at 86°40′. It leaves at 13:22, for Pushya.

Add the Sun's and the Moon's places among the stars: 191.7° + 89.3° = 281°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 02:09 Wed, then Shubha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Saptami is Vishti and the second Bava. Vishti runs until 07:12, when the lead reaches 258°; Bava until 18:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:35 to 06:35 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 17 Oct, inside the month. The next new moon, 6 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 6 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: 16 Mar 1991, 05:10 Sat. Since then the Sun has moved 220.2° round the stars. Vikram Samvat numbers that year 2048; Shaka Samvat numbers it 1913.
