Panchang in Codcod, Western Visayas, Philippines Sat 4 Feb 1978

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 4 Feb only, at 06:10: Sat 4 Feb. Vaishnavas test arunodaya: Dashami ended at 14:46 Fri, before it (04:34–06:10).

Shattila 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, 06:10 here. Dashami ended at 14:46 Fri, before it. Ekadashi ends at 11:55, when the lead reaches 312°. The lead passed 180° at the full moon of 24 Jan, so the Moon is waning: Krishna paksha.

The night of Fri 3 Feb ran from sunset 17:51 Fri to sunrise 06:10, 12 h 19 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 17:52, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:52 to 06:09 Sun, splits into 8 choghadiyas of 1 h 32 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 4 at 236°40′. It leaves at 06:20, for Mula.

Add the Sun's and the Moon's places among the stars: 291.2° + 239.9° = 531.1°, one full turn and 171.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 09:36, then Harshana.

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 01:23, when the lead reached 306°; Balava runs until 11:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:09 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 7 Feb, finds it in Makara and begins Magha.

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 7 Feb, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 1977, 02:32 Sun. Since then the Sun has moved 315.7° round the stars. Vikram Samvat numbers that year 2034; Shaka Samvat numbers it 1899.
