Panchang in Sevan, Gegharkunik, Armenia Mon 14 Feb 2011

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 14 Feb only, at 07:55: Mon 14 Feb. Vaishnavas test arunodaya: Dashami ended at 00:27, before it (06:19–07:55).

Jaya Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 07:55 here. Dashami ended at 00:27, before it. Ekadashi ends at 23:28, when the lead reaches 132°. The lead passed 0° at the new moon of 3 Feb, so the Moon is waxing: Shukla paksha.

The night of Sun 13 Feb ran from sunset 18:32 Sun to sunrise 07:55, 13 h 23 m. Cut into 15 muhurtas of 53 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:55 to 18:33, splits into 8 choghadiyas of 1 h 19 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:33 to 07:54 Tue, splits into 8 choghadiyas of 1 h 40 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 4 at 63°20′. It leaves at 11:01, for Ardra.

Add the Sun's and the Moon's places among the stars: 301.1° + 64.9° = 366°, one full turn and 6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 19:59, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija runs until 12:04, when the lead reaches 126°; Vishti until 23:28.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:55 to 07:54 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: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 5 Mar, finds it in Kumbha and begins Phalguna.

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 3 Feb, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2010, 01:01 Tue. Since then the Sun has moved 329.9° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
