Panchang in Sevan, Gegharkunik, Armenia Fri 25 Jan 1907

Smartas test Ekadashi at sunrise. It holds both sunrises, 07:15 on Thu 24 Jan and 07:14 on Fri 25 Jan. Ekadashi (05:00 Thu 24 Jan to 07:38 Fri 25 Jan) and Dwadashi (07:38 Fri 25 Jan to 10:17 Sat 26 Jan) are both longer than their day; when both grow, Smartas take the later day: Fri 25 Jan. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Jaya Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 07:16 here. Dashami ended at 05:02 Thu, before it. Ekadashi ends at 07:40, when the lead reaches 132°. The lead passed 0° at the new moon of 14 Jan, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 05:02 Thu, before sunrise at 07:17 Thu, and ends at 07:40, after the next sunrise at 07:16. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Thu 24 Jan ran from sunset 17:06 Thu to sunrise 07:16, 14 h 10 m. Cut into 15 muhurtas of 56 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:16 to 17:08, splits into 8 choghadiyas of 1 h 14 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:08 to 07:16 Sat, 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′. Rohini spans 40°00′–53°20′; the Moon entered its pada 4 at 50°. It leaves at 07:17, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 281.5° + 53.3° = 334.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 05:24 Sat, then Vaidhriti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija ended at 18:20 Thu, when the lead reached 126°; Vishti runs until 07:40.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:16 to 07:16 Sat, so the hours after midnight still belong to Shukrawara.

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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 12 Feb, finds it in Kumbha and begins Phalguna.

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 14 Jan, with the Sun in Makara, began Magha. This Shukla paksha reads Magha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1906, 02:51 Sun. Since then the Sun has moved 300.6° round the stars. Vikram Samvat numbers that year 1963; Shaka Samvat numbers it 1828.
