Panchang in Sevan, Gegharkunik, Armenia Sat 10 May 1980

Smartas test Ekadashi at sunrise. It begins at 07:37 on Sat 10 May, after that sunrise (05:48), and ends at 04:48 on Sun 11 May, before the next (05:47 Sun): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Sat 10 May.

Apara Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 05:48 here. Navami ended at 10:03 Fri, before it. Dashami ends at 07:37, when the lead reaches 300°. The lead passed 180° at the full moon of 30 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 07:37 and ended at 04:48 Sun, between the sunrises of 05:48 and 05:47 Sun. Saturday reads Dashami and Sunday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Fri 9 May ran from sunset 20:03 Fri to sunrise 05:48, 9 h 45 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:48 to 20:04, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:04 to 05:47 Sun, splits into 8 choghadiyas of 1 h 12 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 Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 2 at 323°20′. It leaves at 19:39, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 26° + 325° = 351°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 19:52, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija ended at 20:53 Fri, when the lead reached 294°; Vishti runs until 07:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:48 to 05:47 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 14 May, inside the month. The next new moon, 14 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 14 May, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1980, 22:55 Sun. Since then the Sun has moved 53.2° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
