Panchang in Sevan, Gegharkunik, Armenia Tue 25 Apr 1911

Smartas test Ekadashi at sunrise: it holds sunrise on Tue 25 Apr only, at 05:06: Tue 25 Apr. Vaishnavas test arunodaya: Dashami ended at 11:12 Mon, before it (03:30–05:06).

Varuthini 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, 05:08 here. Dashami ended at 11:14 Mon, before it. Ekadashi ends at 10:34, when the lead reaches 312°. The lead passed 180° at the full moon of 13 Apr, so the Moon is waning: Krishna paksha.

The night of Mon 24 Apr ran from sunset 18:46 Mon to sunrise 05:08, 10 h 22 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:08 to 18:48, splits into 8 choghadiyas of 1 h 42 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:48 to 05:07 Wed, splits into 8 choghadiyas of 1 h 17 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 Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 1 at 320°. It leaves at 04:03 Wed, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 11.1° + 320.3° = 331.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 08:15, then Indra.

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 23:00 Mon, when the lead reached 306°; Balava runs until 10:34.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:08 to 05:07 Wed, so the hours after midnight still belong to Mangalawara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 29 Apr, finds it in Mesha and begins Vaishakha.

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 29 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 30 Mar 1911, 15:37 Thu. Since then the Sun has moved 25° round the stars. Vikram Samvat numbers that year 1968; Shaka Samvat numbers it 1833.
