Panchang in Sevan, Gegharkunik, Armenia Sat 28 Dec 2013

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 28 Dec only, at 08:22: Sat 28 Dec. Vaishnavas test arunodaya: Dashami ended at 05:25, before it (06:46–08:22).

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, 08:22 here. Dashami ended at 05:25, before it. Ekadashi ends at 03:49 Sun, when the lead reaches 312°. The lead passed 180° at the full moon of 17 Dec, so the Moon is waning: Krishna paksha.

The night of Fri 27 Dec ran from sunset 17:39 Fri to sunrise 08:22, 14 h 43 m. Cut into 15 muhurtas of 58 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 08:22 to 17:40, splits into 8 choghadiyas of 1 h 9 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:40 to 08:22 Sun, splits into 8 choghadiyas of 1 h 50 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 3 at 193°20′. It leaves at 18:39, for Vishakha.

Add the Sun's and the Moon's places among the stars: 252.5° + 194.1° = 446.6°, one full turn and 86.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 19:14, then Dhriti.

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 runs until 16:43, when the lead reaches 306°; Balava until 03:49 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 08:22 to 08:22 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 16 Dec, inside the month. The next new moon, 1 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 1 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: 10 Apr 2013, 13:35 Wed. Since then the Sun has moved 255.9° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
