Panchang in Sevan, Gegharkunik, Armenia Sun 17 Sep 1922

Smartas test Ekadashi at sunrise: it holds sunrise on Sun 17 Sep only, at 05:39: Sun 17 Sep. Vaishnavas test arunodaya: Dashami ended at 23:05 Sat, before it (04:03–05:39).

Indira 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, 05:41 here. Dashami ended at 23:07 Sat, before it. Ekadashi ends at 20:57, when the lead reaches 312°. The lead passed 180° at the full moon of 6 Sep, so the Moon is waning: Krishna paksha.

The night of Sat 16 Sep ran from sunset 18:08 Sat to sunrise 05:41, 11 h 33 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:41 to 18:07, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 05:42 Mon, splits into 8 choghadiyas of 1 h 26 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 1 at 93°20′. It leaves at 02:37 Mon, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 150.6° + 94.2° = 244.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 19:05, then Shiva.

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 runs until 10:07, when the lead reaches 306°; Balava until 20:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:41 to 05:42 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 21 Sep, finds it in Kanya and begins Ashwina.

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 21 Sep, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 1922, 16:03 Tue. Since then the Sun has moved 166.3° round the stars. Vikram Samvat numbers that year 1979; Shaka Samvat numbers it 1844.
