Panchang in Sevan, Gegharkunik, Armenia Sat 20 May 1933

Smartas test Ekadashi at sunrise. It holds both sunrises, 04:40 on Fri 19 May and 04:39 on Sat 20 May. Ekadashi (04:09 Fri 19 May to 05:17 Sat 20 May) and Dwadashi (05:17 Sat 20 May to 06:50 Sun 21 May) are both longer than their day; when both grow, Smartas take the later day: Sat 20 May. Vaishnavas test arunodaya: on Fri 19 May Dashami lasts until 04:09, inside it (03:04–04:40); on Sat 20 May Ekadashi holds all of it.

Apara 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, 04:39 here. Dashami ended at 04:09 Fri, before it. Ekadashi ends at 05:17, when the lead reaches 312°. The lead passed 180° at the full moon of 10 May, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Ekadashi began at 04:09 Fri, before sunrise at 04:40 Fri, and ends at 05:17, after the next sunrise at 04:39. Both days read Ekadashi: it is a vriddhi tithi here.

The night of Fri 19 May ran from sunset 19:12 Fri to sunrise 04:39, 9 h 27 m. Cut into 15 muhurtas of 37 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:39 to 19:13, splits into 8 choghadiyas of 1 h 49 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:13 to 04:38 Sun, splits into 8 choghadiyas of 1 h 10 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 1 at 346°40′. It leaves at 05:26 Sun, for Ashwini.

Add the Sun's and the Moon's places among the stars: 35.7° + 347.4° = 383.1°, one full turn and 23.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 13°20′–26°40′ is the 2nd, Priti. It ends at 11:15, then Ayushmana.

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 16:39 Fri, when the lead reached 306°; Balava runs until 05:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:39 to 04:38 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, 24 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 24 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: 26 Mar 1933, 06:20 Sun. Since then the Sun has moved 53.6° round the stars. Vikram Samvat numbers that year 1990; Shaka Samvat numbers it 1855.
