Panchang in Sevan, Gegharkunik, Armenia Tue 31 Jan 1939

Smartas test Ekadashi at sunrise: it holds sunrise on Tue 31 Jan only, at 07:11: Tue 31 Jan. Vaishnavas test arunodaya: Dashami ended at 03:29, before it (05:35–07:11).

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, 07:11 here. Dashami ended at 03:29, before it. Ekadashi ends at 01:08 Wed, when the lead reaches 132°. The lead passed 0° at the new moon of 20 Jan, so the Moon is waxing: Shukla paksha.

The night of Mon 30 Jan ran from sunset 17:14 Mon to sunrise 07:11, 13 h 57 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:11 to 17:15, splits into 8 choghadiyas of 1 h 15 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:15 to 07:10 Wed, splits into 8 choghadiyas of 1 h 44 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 3 at 46°40′. It leaves at 13:48, for Mrigashira.

Add the Sun's and the Moon's places among the stars: 287.4° + 49.4° = 336.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 22:37, 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 runs until 14:23, when the lead reaches 126°; Vishti until 01:08 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:11 to 07:10 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 19 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 20 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: 31 Mar 1938, 21:51 Thu. Since then the Sun has moved 300° round the stars. Vikram Samvat numbers that year 1995; Shaka Samvat numbers it 1860.
