Panchang in Sevan, Gegharkunik, Armenia Mon 19 Jan 2004

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 10:12 on Mon 19 Jan to 07:07 on Tue 20 Jan, so only Monday’s pradosha (18:01–20:53) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 08:19 here. Ekadashi ended at 13:08 Sun, before it. Dwadashi ends at 10:12, when the lead reaches 324°. The lead passed 180° at the full moon of 7 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 10:12 and ended at 07:07 Tue, between the sunrises of 08:19 and 08:19 Tue. Monday reads Dwadashi and Tuesday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Sun 18 Jan ran from sunset 18:00 Sun to sunrise 08:19, 14 h 19 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:19 to 18:01, splits into 8 choghadiyas of 1 h 12 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:01 to 08:19 Tue, splits into 8 choghadiyas of 1 h 47 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 4 at 236°40′. It leaves at 12:30, for Mula.

Add the Sun's and the Moon's places among the stars: 274.5° + 237.4° = 511.9°, one full turn and 151.9°. 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 20:35, then Vyaghata.

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 23:42 Sun, when the lead reached 318°; Taitila runs until 10:12.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:19 to 08:19 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 22 Jan, 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 22 Jan, 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: 2 Apr 2003, 00:18 Wed. Since then the Sun has moved 286.7° round the stars. Vikram Samvat numbers that year 2060; Shaka Samvat numbers it 1925.
