Panchang in Sevan, Gegharkunik, Armenia Fri 2 May 1913

Smartas test Ekadashi at sunrise. It holds both sunrises, 04:58 on Thu 1 May and 04:56 on Fri 2 May. Ekadashi (03:14 Thu 1 May to 05:43 Fri 2 May) and Dwadashi (05:43 Fri 2 May to 07:53 Sat 3 May) are both longer than their day; when both grow, Smartas take the later day: Fri 2 May. Vaishnavas test arunodaya: over two sunrises, they too fast on the second.

Varuthini 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, 04:58 here. Dashami ended at 03:16 Thu, before it. Ekadashi ends at 05:45, when the lead reaches 312°. The lead passed 180° at the full moon of 21 Apr, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 03:16 Thu, before sunrise at 05:00 Thu, and ends at 05:45, after the next sunrise at 04:58. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Thu 1 May ran from sunset 18:54 Thu to sunrise 04:58, 10 h 4 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:58 to 18:55, 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 night here, 18:55 to 04:57 Sat, 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 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 11:34, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 18.4° + 330.1° = 348.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 02:22 Sat, 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 ended at 16:32 Thu, when the lead reached 306°; Balava runs until 05:45.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:58 to 04:57 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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 6 May, finds it in Mesha and begins Vaishakha.

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 6 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 6 Apr 1913, 20:47 Sun. Since then the Sun has moved 24.7° round the stars. Vikram Samvat numbers that year 1970; Shaka Samvat numbers it 1835.
