Panchang in Sevan, Gegharkunik, Armenia Fri 19 Oct 1900

Smartas test Ekadashi at sunrise. It holds both sunrises, 06:11 on Thu 18 Oct and 06:12 on Fri 19 Oct. Ekadashi (04:16 Thu 18 Oct to 06:28 Fri 19 Oct) and Dwadashi (06:28 Fri 19 Oct to 08:54 Sat 20 Oct) are both longer than their day; when both grow, Smartas take the later day: Fri 19 Oct. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Rama 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, 06:14 here. Dashami ended at 04:18 Thu, before it. Ekadashi ends at 06:30, when the lead reaches 312°. The lead passed 180° at the full moon of 8 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:18 Thu, before sunrise at 06:13 Thu, and ends at 06:30, after the next sunrise at 06:14. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Thu 18 Oct ran from sunset 17:16 Thu to sunrise 06:14, 12 h 58 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:14 to 17:15, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:15 to 06:15 Sat, splits into 8 choghadiyas of 1 h 37 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 1 at 133°20′. It leaves at 06:25 Sat, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 182.8° + 134.7° = 317.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 10:53, then Brahma.

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 ended at 17:22 Thu, when the lead reached 306°; Balava runs until 06:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:14 to 06:15 Sat, so the hours after midnight still belong to Shukrawara.

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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 23 Oct, finds it in Tula and begins Kartika.

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 23 Oct, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 30 Mar 1900, 23:30 Fri. Since then the Sun has moved 195.6° round the stars. Vikram Samvat numbers that year 1957; Shaka Samvat numbers it 1822.
