Panchang in Ipameri, Goiás, Brazil Fri 4 Oct 2097

The shraddha for all ancestors is done in aparahna, the fourth fifth of the day. Amavasya runs from 09:44 on Fri 4 Oct to 08:47 on Sat 5 Oct, so only Friday’s aparahna (13:15–15:43) falls within it. No text giving Sarva Pitru Amavasya’s time was found; aparahna is Tithika’s convention.

Sarva Pitru Amavasya: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:51 here. Trayodashi ended at 11:09 Thu, before it. Chaturdashi ends at 09:44, when the lead reaches 348°. The lead passed 180° at the full moon of 21 Sep, so the Moon is waning: Krishna paksha.

The night of Thu 3 Oct ran from sunset 18:10 Thu to sunrise 05:51, 11 h 41 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:51 to 18:10, 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, 18:10 to 05:50 Sat, 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 2 at 150°. It leaves at 18:47, for Hasta.

Add the Sun's and the Moon's places among the stars: 166.7° + 152.7° = 319.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 06:50, then Brahma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 22:23 Thu, when the lead reached 342°; Shakuni runs until 09:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:51 to 05:50 Sat, so the hours after midnight still belong to Shukrawara.

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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 5 Oct, finds it in Kanya and begins Ashwina.

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 5 Oct, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 2097, 06:28 Fri. Since then the Sun has moved 168.6° round the stars. Vikram Samvat numbers that year 2154; Shaka Samvat numbers it 2019.
