Panchang in Sevan, Gegharkunik, Armenia Fri 4 Jan 2008

Smartas test Ekadashi at sunrise. It holds both sunrises, 08:23 on Thu 3 Jan and 08:23 on Fri 4 Jan. Ekadashi (05:56 Thu 3 Jan to 08:30 Fri 4 Jan) and Dwadashi (08:30 Fri 4 Jan to 10:51 Sat 5 Jan) are both longer than their day; when both grow, Smartas take the later day: Fri 4 Jan. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Saphala Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 08:23 here. Dashami ended at 05:56 Thu, before it. Ekadashi ends at 08:30, when the lead reaches 312°. The lead passed 180° at the full moon of 24 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:56 Thu, before sunrise at 08:23 Thu, and ends at 08:30, after the next sunrise at 08:23. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Thu 3 Jan ran from sunset 17:45 Thu to sunrise 08:23, 14 h 38 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:23 to 17:45, splits into 8 choghadiyas of 1 h 10 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:45 to 08:23 Sat, splits into 8 choghadiyas of 1 h 49 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 4 at 210°. It leaves at 12:47, for Anuradha.

Add the Sun's and the Moon's places among the stars: 259.2° + 211.1° = 470.3°, one full turn and 110.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 02:16 Sat, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava ended at 19:14 Thu, when the lead reached 306°; Balava runs until 08:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:23 to 08:23 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 8 Jan, finds it in Dhanu and begins Pausha.

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 8 Jan, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 2007, 06:42 Mon. Since then the Sun has moved 285° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
