Panchang in Codcod, Western Visayas, Philippines Fri 23 Oct 1981

Smartas test Ekadashi at sunrise: it holds sunrise on Fri 23 Oct only, at 05:36: Fri 23 Oct. Vaishnavas test arunodaya: Dashami ended at 22:23 Thu, before it (04:00–05:36).

Rama 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, 05:36 here. Dashami ended at 22:23 Thu, before it. Ekadashi ends at 22:46, when the lead reaches 312°. The lead passed 180° at the full moon of 13 Oct, so the Moon is waning: Krishna paksha.

The night of Thu 22 Oct ran from sunset 17:26 Thu to sunrise 05:36, 12 h 10 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:36 to 17:26, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:26 to 05:36 Sat, splits into 8 choghadiyas of 1 h 31 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 3 at 126°40′. It leaves at 13:01, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 185.8° + 129.4° = 315.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 14:00, then Brahma.

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 10:31, when the lead reaches 306°; Balava until 22:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:36 to 05:36 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: Kanya gives Ashwina. The Sun enters Tula on 17 Oct, inside the month. The next new moon, 28 Oct, finds it in Tula and begins Kartika.

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 28 Oct, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 1981, 04:19 Sun. Since then the Sun has moved 194.4° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
