Panchang in Baoding, Hebei, China Tue 1 Feb 2011

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 07:43 on Tue 1 Feb to 08:56 on Wed 2 Feb, so only Tuesday night’s nishitha (00:03 Wed–00:58 Wed) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Baoding

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 07:24 here. Dwadashi ended at 06:54 Mon, before it. Trayodashi ends at 07:43, when the lead reaches 336°. The lead passed 180° at the full moon of 20 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:54 Mon, before sunrise at 07:25 Mon, and ends at 07:43, after the next sunrise at 07:24. Both days read Trayodashi: it is a vriddhi tithi here.

The night of Mon 31 Jan ran from sunset 17:37 Mon to sunrise 07:24, 13 h 47 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:24 to 17:38, splits into 8 choghadiyas of 1 h 16 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:38 to 07:24 Wed, splits into 8 choghadiyas of 1 h 43 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 Ashadha spans 253°20′–266°40′; the Moon entered its pada 4 at 263°20′. It leaves at 13:21, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 287.7° + 263.6° = 551.3°, one full turn and 191.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 22:54, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja ended at 19:16 Mon, when the lead reached 330°; Vanija runs until 07:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:24 to 07:24 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: 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 3 Feb, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

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 316.5° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
