Panchang in Baoding, Hebei, China Sun 11 Sep 2022

The first shraddha of Pitru Paksha is done in aparahna, the fourth fifth of the day. Pratipada runs from 17:59 on Sat 10 Sep to 15:45 on Sun 11 Sep, so it touches only Sunday’s aparahna (13:30–16:01). No text giving Pitru Paksha begins’s time was found; aparahna is Tithika’s convention.

Pitru Paksha begins: every date in Baoding

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 180°–192° is the 16th, Krishna Pratipada. A day takes the tithi in force at its sunrise, 05:55 here. Purnima ended at 17:59 Sat, before it. Pratipada ends at 15:45, when the lead reaches 192°. The lead passed 180° at the full moon of 10 Sep, so the Moon is waning: Krishna paksha.

The night of Sat 10 Sep ran from sunset 18:35 Sat to sunrise 05:55, 11 h 20 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:55 to 18:33, 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, 18:33 to 05:56 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′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 4 at 330°. It leaves at 10:31, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 144° + 330.6° = 474.6°, one full turn and 114.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 14:29, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Balava and the second Kaulava. Balava ended at 04:48, when the lead reached 186°; Kaulava runs until 15:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:55 to 05:56 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 26 Sep, 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 26 Sep, 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: 1 Apr 2022, 14:24 Fri. Since then the Sun has moved 156.7° round the stars. Vikram Samvat numbers that year 2079; Shaka Samvat numbers it 1944.
