Panchang in Sevan, Gegharkunik, Armenia Sat 4 Jun 2005

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 00:52 on Sat 4 Jun to 01:09 on Sun 5 Jun, so only Saturday’s pradosha (21:26–23:15) falls within it. 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 began at 01:09 on Sun 5 Jun, before that night’s nishitha, and ended at 01:50 on Mon 6 Jun, partway into the next. The Nirnayasindhu takes the night Chaturdashi fills: Sat 4 Jun. 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, 06:30 here. Dwadashi ended at 00:52, before it. Trayodashi ends at 01:09 Sun, when the lead reaches 336°. The lead passed 180° at the full moon of 24 May, so the Moon is waning: Krishna paksha.

The night of Fri 3 Jun ran from sunset 21:25 Fri to sunrise 06:30, 9 h 5 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:30 to 21:26, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:26 to 06:30 Sun, splits into 8 choghadiyas of 1 h 8 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 01:44 Sun, for Krittika.

Add the Sun's and the Moon's places among the stars: 49.6° + 16.4° = 66°. The sum, cut into 27 parts of 13°20′, gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 07:37, then Atiganda.

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 12:58, when the lead reaches 330°; Vanija until 01:09 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:30 to 06:30 Sun, so the hours after midnight still belong to Shaniwara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 7 Jun, finds it in Vrishabha and begins Jyeshtha.

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 Jun, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha 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 54.4° round the stars. Vikram Samvat numbers that year 2062; Shaka Samvat numbers it 1927.
