Panchang in Myshkin, Yaroslavl Oblast, Russia Wed 5 Feb 1997

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 04:42 on Wed 5 Feb to 01:29 on Thu 6 Feb, so only Wednesday’s pradosha (17:00–20:04) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Myshkin

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 01:29 on Thu 6 Feb to 21:53 on Thu 6 Feb, between the two nights’ nishitha, touching neither. The Nirnayasindhu then takes the earlier day: Wed 5 Feb. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

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, 08:20 here. Dwadashi ended at 04:42, before it. Trayodashi ends at 01:29 Thu, when the lead reaches 336°. The lead passed 180° at the full moon of 23 Jan, so the Moon is waning: Krishna paksha.

Sunrise here, 07:07, came before Dwadashi ended at 07:12: this day reads Dwadashi. Trayodashi ends at 03:59 Thu, before the next sunrise, so no day here reads Trayodashi: it is kshaya.

The night of Tue 4 Feb ran from sunset 16:58 Tue to sunrise 08:20, 15 h 22 m. Cut into 15 muhurtas of 1 h 1 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:20 to 17:00, splits into 8 choghadiyas of 1 h 5 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:00 to 08:18 Thu, splits into 8 choghadiyas of 1 h 54 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 2 at 256°40′. It leaves at 21:11, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 292.6° + 258.7° = 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 21:25, 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 runs until 15:09, when the lead reaches 330°; Vanija until 01:29 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:20 to 08:18 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, 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: 19 Mar 1996, 13:44 Tue. Since then the Sun has moved 317.3° round the stars. Vikram Samvat numbers that year 2053; Shaka Samvat numbers it 1918.
