Panchang in Sevan, Gegharkunik, Armenia Sun 26 Feb 1961

Smartas test Ekadashi at sunrise. It holds both sunrises, 07:40 on Sat 25 Feb and 07:39 on Sun 26 Feb. Ekadashi (05:18 Sat 25 Feb to 07:52 Sun 26 Feb) and Dwadashi (07:52 Sun 26 Feb to 10:31 Mon 27 Feb) are both longer than their day; when both grow, Smartas take the later day: Sun 26 Feb. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

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, 07:39 here. Dashami ended at 05:18 Sat, before it. Ekadashi ends at 07:52, when the lead reaches 132°. The lead passed 0° at the new moon of 15 Feb, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:18 Sat, before sunrise at 07:40 Sat, and ends at 07:52, after the next sunrise at 07:39. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Sat 25 Feb ran from sunset 18:46 Sat to sunrise 07:39, 12 h 53 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:39 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 Mon, 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 2 at 83°20′. It leaves at 22:45, for Pushya.

Add the Sun's and the Moon's places among the stars: 314° + 85.9° = 399.9°, one full turn and 39.9°. 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 07:49, 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 18:34 Sat, when the lead reached 126°; Vishti runs until 07:52.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:39 to 07:37 Mon, so the hours after midnight still belong to Raviwara.

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, 16 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 15 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: 27 Mar 1960, 11:37 Sun. Since then the Sun has moved 330.7° round the stars. Vikram Samvat numbers that year 2017; Shaka Samvat numbers it 1882.
