Panchang in Sevan, Gegharkunik, Armenia Mon 16 Sep 1918

Smartas test Ekadashi at sunrise. It begins at 05:57 on Mon 16 Sep, after that sunrise (05:38), and ends at 04:25 on Tue 17 Sep, before the next (05:39 Tue): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Mon 16 Sep.

Parsva Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 05:40 here. Navami ended at 06:39 Sun, before it. Dashami ends at 05:59, when the lead reaches 120°. The lead passed 0° at the new moon of 5 Sep, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:59 and ended at 04:27 Tue, between the sunrises of 05:40 and 05:41 Tue. Monday reads Dashami and Tuesday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Sun 15 Sep ran from sunset 18:10 Sun to sunrise 05:40, 11 h 30 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:40 to 18:09, 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, 18:09 to 05:41 Tue, 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 1 at 266°40′. It leaves at 23:57, for Shravana.

Add the Sun's and the Moon's places among the stars: 149.7° + 269.5° = 419.2°, one full turn and 59.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 17:51, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 18:25 Sun, when the lead reached 114°; Garaja runs until 05:59.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:40 to 05:41 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: Simha gives Bhadrapada. The Sun enters Kanya on 16 Sep, inside the month. The next new moon, 5 Oct, 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 5 Sep, with the Sun in Simha, began Bhadrapada. This Shukla paksha reads Bhadrapada in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1918, 07:33 Thu. Since then the Sun has moved 151.9° round the stars. Vikram Samvat numbers that year 1975; Shaka Samvat numbers it 1840.
