Panchang in Codcod, Western Visayas, Philippines Mon 11 May 2037

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 11 May only, at 05:26: Mon 11 May. Vaishnavas test arunodaya: Dashami ended at 07:09 Sun, before it (03:50–05:26).

Apara Ekadashi: every date in Codcod

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, 05:26 here. Dashami ended at 07:09 Sun, before it. Ekadashi ends at 09:25, when the lead reaches 312°. The lead passed 180° at the full moon of 30 Apr, so the Moon is waning: Krishna paksha.

The night of Sun 10 May ran from sunset 18:00 Sun to sunrise 05:26, 11 h 26 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:26 to 18:00, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:00 to 05:26 Tue, splits into 8 choghadiyas of 1 h 25 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 Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 1 at 333°20′. It leaves at 02:01 Tue, for Revati.

Add the Sun's and the Moon's places among the stars: 26.2° + 336.3° = 362.5°, one full turn and 2.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 01:24 Tue, then Priti.

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 20:19 Sun, when the lead reached 306°; Balava runs until 09:25.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:26 to 05:26 Tue, so the hours after midnight still belong to Somawara.

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, 15 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 15 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: 17 Mar 2037, 07:36 Tue. Since then the Sun has moved 53.9° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
