Panchang in Sevan, Gegharkunik, Armenia Thu 8 May 1930

Smartas test Ekadashi at sunrise: it holds sunrise on Thu 8 May only, at 04:51: Thu 8 May. Vaishnavas test arunodaya: Dashami ended at 02:33, before it (03:15–04:51).

Mohini 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, 04:51 here. Dashami ended at 02:33, before it. Ekadashi ends at 00:43 Fri, when the lead reaches 132°. The lead passed 0° at the new moon of 28 Apr, so the Moon is waxing: Shukla paksha.

The night of Wed 7 May ran from sunset 19:00 Wed to sunrise 04:51, 9 h 51 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:51 to 19:01, 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 night here, 19:01 to 04:50 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 4 at 143°20′. It leaves at 07:30, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 23.9° + 145.1° = 169°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 11:49, then Harshana.

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 13:36, when the lead reaches 126°; Vishti until 00:43 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:51 to 04:50 Fri, so the hours after midnight still belong to Guruwara.

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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 28 May, finds it in Vrishabha and begins Jyeshtha.

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 Apr, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 30 Mar 1930, 08:46 Sun. Since then the Sun has moved 38° round the stars. Vikram Samvat numbers that year 1987; Shaka Samvat numbers it 1852.
