Panchang in Sevan, Gegharkunik, Armenia Sat 25 Sep 1943

Smartas test Ekadashi at sunrise. It holds both sunrises, 05:48 on Fri 24 Sep and 05:49 on Sat 25 Sep. Ekadashi (03:46 Fri 24 Sep to 06:26 Sat 25 Sep) and Dwadashi (06:26 Sat 25 Sep to 08:59 Sun 26 Sep) are both longer than their day; when both grow, Smartas take the later day: Sat 25 Sep. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

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, 05:49 here. Dashami ended at 03:46 Fri, before it. Ekadashi ends at 06:26, when the lead reaches 312°. The lead passed 180° at the full moon of 14 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 03:46 Fri, before sunrise at 05:48 Fri, and ends at 06:26, after the next sunrise at 05:49. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 24 Sep ran from sunset 17:55 Fri to sunrise 05:49, 11 h 54 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:49 to 17:54, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:54 to 05:50 Sun, splits into 8 choghadiyas of 1 h 29 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 02:30 Sun, for Magha.

Add the Sun's and the Moon's places among the stars: 158.1° + 109.8° = 267.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 266°40′–280°00′ is the 21st, Siddha. It ends at 04:28 Sun, then Sadhya.

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 17:06 Fri, when the lead reached 306°; Balava runs until 06:26.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:49 to 05:50 Sun, so the hours after midnight still belong to Shaniwara.

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, 29 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 29 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: 5 Apr 1943, 00:52 Mon. Since then the Sun has moved 166.9° round the stars. Vikram Samvat numbers that year 2000; Shaka Samvat numbers it 1865.
