Panchang in Sevan, Gegharkunik, Armenia Mon 26 Feb 2018

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 26 Feb only, at 07:38: Mon 26 Feb. Vaishnavas test arunodaya: Dashami ended at 18:39 Sun, before it (06:02–07:38).

Amalaki 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, 07:38 here. Dashami ended at 18:39 Sun, before it. Ekadashi ends at 15:59, when the lead reaches 132°. The lead passed 0° at the new moon of 16 Feb, so the Moon is waxing: Shukla paksha.

The night of Sun 25 Feb ran from sunset 18:46 Sun to sunrise 07:38, 12 h 52 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:38 to 18:47, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:47 to 07:37 Tue, splits into 8 choghadiyas of 1 h 36 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 1 at 80°. It leaves at 04:29 Tue, for Pushya.

Add the Sun's and the Moon's places among the stars: 313.4° + 80.7° = 394.1°, one full turn and 34.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 16:49, then Saubhagya.

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 ended at 05:21, when the lead reached 126°; Vishti runs until 15:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:38 to 07:37 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 17 Mar, finds it in Meena and begins Chaitra.

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 16 Feb, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 06:57 Tue. Since then the Sun has moved 329.9° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
