Panchang in Sevan, Gegharkunik, Armenia Mon 27 Mar 2006

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 01:36 on Mon 27 Mar to 22:12 on Mon 27 Mar, so it touches only Monday’s pradosha (20:19–22:37). No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sevan

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 22:12 on Mon 27 Mar to 18:42 on Tue 28 Mar, so only Monday night’s nishitha (01:41 Tue–02:28 Tue) falls within it. 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, 07:52 here. Dwadashi ended at 01:36, before it. Trayodashi ends at 22:12, when the lead reaches 336°. The lead passed 180° at the full moon of 15 Mar, so the Moon is waning: Krishna paksha.

The night of Sun 26 Mar ran from sunset 20:17 Sun to sunrise 07:52, 11 h 35 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:52 to 20:19, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:19 to 07:50 Tue, splits into 8 choghadiyas of 1 h 26 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′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 1 at 306°40′. It leaves at 23:53, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 342.4° + 309.9° = 652.3°, one full turn and 292.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 09:21, then Shubha.

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 11:56, when the lead reaches 330°; Vanija until 22:12.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:52 to 07:50 Tue, so the hours after midnight still belong to Somawara.

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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 29 Mar, finds it in Meena and begins Chaitra.

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 29 Mar, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 9 Apr 2005, 01:32 Sat. Since then the Sun has moved 347.2° round the stars. Vikram Samvat numbers that year 2062; Shaka Samvat numbers it 1927.
