Panchang in Sevan, Gegharkunik, Armenia Thu 18 Feb 2016

Smartas test Ekadashi at sunrise: it holds sunrise on Thu 18 Feb only, at 07:50: Thu 18 Feb. Vaishnavas test arunodaya: Dashami ended at 20:36 Wed, before it (06:14–07:50).

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, 07:50 here. Dashami ended at 20:36 Wed, before it. Ekadashi ends at 20:03, when the lead reaches 132°. The lead passed 0° at the new moon of 8 Feb, so the Moon is waxing: Shukla paksha.

The night of Wed 17 Feb ran from sunset 18:36 Wed to sunrise 07:50, 13 h 14 m. Cut into 15 muhurtas of 52 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:50 to 18:37, splits into 8 choghadiyas of 1 h 20 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:37 to 07:49 Fri, splits into 8 choghadiyas of 1 h 39 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 2 at 70°. It leaves at 00:53 Fri, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 304.8° + 70.6° = 375.4°, one full turn and 15.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 02:47 Fri, then Ayushmana.

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 08:16, when the lead reaches 126°; Vishti until 20:03.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:50 to 07:49 Fri, so the hours after midnight still belong to Guruwara.

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, 9 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 8 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: 20 Mar 2015, 13:36 Fri. Since then the Sun has moved 329.4° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
