Panchang in Baoding, Hebei, China Sun 5 Feb 1978

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 08:45 on Sun 5 Feb to 05:24 on Mon 6 Feb, so only Sunday’s pradosha (17:43–20:26) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Baoding

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 07:21 here. Ekadashi ended at 11:55 Sat, before it. Dwadashi ends at 08:45, when the lead reaches 324°. The lead passed 180° at the full moon of 24 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 08:45 and ended at 05:24 Mon, between the sunrises of 07:21 and 07:20 Mon. Sunday reads Dwadashi and Monday reads Chaturdashi: Trayodashi is a kshaya tithi here.

Baoding · UTC+8

Sunrise here, 07:21, came before Dwadashi ended at 08:45: this day reads Dwadashi. Trayodashi ends at 05:24 Mon, before the next sunrise, so no day here reads Trayodashi: it is kshaya.

The night of Sat 4 Feb ran from sunset 17:42 Sat to sunrise 07:21, 13 h 39 m. Cut into 15 muhurtas of 54 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:21 to 17:43, splits into 8 choghadiyas of 1 h 17 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:43 to 07:20 Mon, splits into 8 choghadiyas of 1 h 42 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 1 at 253°20′. It leaves at 01:23 Mon, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 292.2° + 255.4° = 547.6°, one full turn and 187.6°. 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 01:52 Mon, then Siddhi.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 22:22 Sat, when the lead reached 318°; Taitila runs until 08:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:21 to 07:20 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 7 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 7 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: 20 Mar 1977, 02:32 Sun. Since then the Sun has moved 316.7° round the stars. Vikram Samvat numbers that year 2034; Shaka Samvat numbers it 1899.
