Panchang in Sevan, Gegharkunik, Armenia Sat 24 Jan 1903

Smartas test Ekadashi at sunrise. It holds both sunrises, 07:16 on Fri 23 Jan and 07:15 on Sat 24 Jan. Ekadashi (07:12 Fri 23 Jan to 09:42 Sat 24 Jan) and Dwadashi (09:42 Sat 24 Jan to 12:19 Sun 25 Jan) are both longer than their day; when both grow, Smartas take the later day: Sat 24 Jan. Vaishnavas test arunodaya: on Fri 23 Jan Dashami lasts until 07:12, inside it (05:40–07:16); on Sat 24 Jan Ekadashi holds all of it.

Shattila 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, 07:17 here. Dashami ended at 07:14 Fri, before it. Ekadashi ends at 09:44, when the lead reaches 312°. The lead passed 180° at the full moon of 13 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 07:14 Fri, before sunrise at 07:18 Fri, and ends at 09:44, after the next sunrise at 07:17. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 23 Jan ran from sunset 17:05 Fri to sunrise 07:17, 14 h 12 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:17 to 17:06, splits into 8 choghadiyas of 1 h 13 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:06 to 07:16 Sun, splits into 8 choghadiyas of 1 h 46 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 2 at 230°. It leaves at 00:42 Sun, for Mula.

Add the Sun's and the Moon's places among the stars: 280.5° + 231.4° = 511.9°, one full turn and 151.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 22:23, then Vyaghata.

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 20:27 Fri, when the lead reached 306°; Balava runs until 09:44.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:17 to 07:16 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: Dhanu gives Pausha. The Sun enters Makara on 13 Jan, inside the month. The next new moon, 28 Jan, finds it in Makara and begins Magha.

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 28 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 8 Apr 1902, 16:49 Tue. Since then the Sun has moved 285.2° round the stars. Vikram Samvat numbers that year 1959; Shaka Samvat numbers it 1824.
