Panchang in Sevan, Gegharkunik, Armenia Fri 10 May 1991

Smartas test Ekadashi at sunrise: it holds sunrise on Fri 10 May only, at 05:49: Fri 10 May. Vaishnavas test arunodaya: Dashami ended at 18:45 Thu, before it (04:13–05:49).

Parama Ekadashi: every date in Sevan

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 300°–312° is the 26th, Krishna Ekadashi. A day takes the tithi in force at its sunrise, 05:49 here. Dashami ended at 18:45 Thu, before it. Ekadashi ends at 18:06, when the lead reaches 312°. The lead passed 180° at the full moon of 29 Apr, so the Moon is waning: Krishna paksha.

The night of Thu 9 May ran from sunset 20:03 Thu to sunrise 05:49, 9 h 46 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:49 to 20:04, 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, 20:04 to 05:48 Sat, 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 Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 4 at 330°. It leaves at 10:20, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 25.2° + 330.8° = 356°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 12:30, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Bava and the second Balava. Bava runs until 06:32, when the lead reaches 306°; Balava until 18:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:49 to 05:48 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 23:37 Sun to 14 May 08:35 Tue the Sun stayed in Mesha, entering Vrishabha at 15 May 05:25 Wed, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha itself.

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 Mesha, begins Vaishakha (Adhik). Until then this Krishna paksha reads Vaishakha (Adhik) here, and Vaishakha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 1991, 12:10 Sat. Since then the Sun has moved 53.7° round the stars. Vikram Samvat numbers that year 2048; Shaka Samvat numbers it 1913.
