Panchang in Baoding, Hebei, China Wed 19 Jan 2011

Purnima follows the tithi at sunrise. Purnima begins at 07:48 on Wed 19 Jan, after that sunrise, and ends at 05:21 on Thu 20 Jan, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 19 Jan. No text giving Purnima’s time was found; sunrise is Tithika’s convention.

Purnima: every date in Baoding

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 07:33 here. Trayodashi ended at 09:43 Tue, before it. Chaturdashi ends at 07:48, when the lead reaches 168°. The lead passed 0° at the new moon of 4 Jan, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Purnima began at 07:48 and ended at 05:21 Thu, between the sunrises of 07:33 and 07:33 Thu. Wednesday reads Chaturdashi and Thursday reads Pratipada: Purnima is a kshaya tithi here.

Baoding · UTC+8

Sunrise here, 07:33, came before Chaturdashi ended at 07:48: this day reads Chaturdashi. Purnima ends at 05:21 Thu, before the next sunrise, so no day here reads Purnima: it is kshaya.

The night of Tue 18 Jan ran from sunset 17:22 Tue to sunrise 07:33, 14 h 11 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:33 to 17:23, splits into 8 choghadiyas of 1 h 13 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:23 to 07:33 Thu, splits into 8 choghadiyas of 1 h 46 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 1 at 80°. It leaves at 01:52 Thu, for Pushya.

Add the Sun's and the Moon's places among the stars: 274.5° + 82.4° = 356.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 12:27, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 20:50 Tue, when the lead reached 162°; Vanija runs until 07:48.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:33 to 07:33 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 3 Feb, finds it in Makara and begins Magha.

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 4 Jan, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2010, 05:01 Tue. Since then the Sun has moved 303.3° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
