Panchang in Sevan, Gegharkunik, Armenia Fri 13 May 2011

Smartas test Ekadashi at sunrise. It begins at 07:51 on Fri 13 May, after that sunrise (06:46), and ends at 04:53 on Sat 14 May, before the next (06:45 Sat): it holds no sunrise. A kshaya Ekadashi is kept on the day it is current: Fri 13 May.

Mohini Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 108°–120° is the 10th, Shukla Dashami. A day takes the tithi in force at its sunrise, 06:46 here. Navami ended at 10:28 Thu, before it. Dashami ends at 07:51, when the lead reaches 120°. The lead passed 0° at the new moon of 3 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 07:51 and ended at 04:53 Sat, between the sunrises of 06:46 and 06:45 Sat. Friday reads Dashami and Saturday reads Dwadashi: Ekadashi is a kshaya tithi here.

The night of Thu 12 May ran from sunset 21:06 Thu to sunrise 06:46, 9 h 40 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:46 to 21:07, 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, 21:07 to 06:45 Sat, 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′. Uttara Phalguni spans 146°40′–160°00′; the Moon entered its pada 1 at 146°40′. It leaves at 03:29 Sat, for Hasta.

Add the Sun's and the Moon's places among the stars: 28° + 147.3° = 175.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 00:14 Sat, then Vajra.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Taitila and the second Garaja. Taitila ended at 21:13 Thu, when the lead reached 114°; Garaja runs until 07:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:46 to 06:45 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 2 Jun, 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 3 May, 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: 3 Apr 2011, 19:32 Sun. Since then the Sun has moved 38.5° round the stars. Vikram Samvat numbers that year 2068; Shaka Samvat numbers it 1933.
