Panchang in Sevan, Gegharkunik, Armenia Fri 22 Oct 1999

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 09:28 on Fri 22 Oct to 07:35 on Sat 23 Oct, so only Friday’s pradosha (19:10–21:48) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 08:17 here. Ekadashi ended at 10:36 Thu, before it. Dwadashi ends at 09:28, when the lead reaches 144°. The lead passed 0° at the new moon of 9 Oct, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 09:28 and ended at 07:35 Sat, between the sunrises of 08:17 and 08:18 Sat. Friday reads Dwadashi and Saturday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Thu 21 Oct ran from sunset 19:12 Thu to sunrise 08:17, 13 h 5 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:17 to 19:10, splits into 8 choghadiyas of 1 h 21 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:10 to 08:18 Sat, splits into 8 choghadiyas of 1 h 38 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 Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 3 at 326°40′. It leaves at 17:52, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 184.4° + 327.8° = 512.2°, one full turn and 152.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 20:49, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava ended at 22:08 Thu, when the lead reached 138°; Balava runs until 09:28.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:17 to 08:18 Sat, so the hours after midnight still belong to Shukrawara.

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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 8 Nov, finds it in Tula and begins Kartika.

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 9 Oct, with the Sun in Kanya, began Ashwina. This Shukla paksha reads Ashwina in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1999, 22:47 Wed. Since then the Sun has moved 211.5° round the stars. Vikram Samvat numbers that year 2056; Shaka Samvat numbers it 1921.
