Panchang in Codcod, Western Visayas, Philippines Mon 2 Mar 1981

Smartas test Ekadashi at sunrise: it holds sunrise on Mon 2 Mar only, at 06:01: Mon 2 Mar. Vaishnavas test arunodaya: Dashami ended at 00:48, before it (04:25–06:01).

Vijaya 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, 06:01 here. Dashami ended at 00:48, before it. Ekadashi ends at 00:59 Tue, when the lead reaches 312°. The lead passed 180° at the full moon of 19 Feb, so the Moon is waning: Krishna paksha.

The night of Sun 1 Mar ran from sunset 17:57 Sun to sunrise 06:01, 12 h 4 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:01 to 17:57, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:57 to 06:01 Tue, splits into 8 choghadiyas of 1 h 30 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 Ashadha spans 253°20′–266°40′; the Moon entered its pada 3 at 260°. It leaves at 18:03, for Uttara Ashadha.

Add the Sun's and the Moon's places among the stars: 317.6° + 260.2° = 577.8°, one full turn and 217.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 21:13, then Variyana.

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 12:59, when the lead reaches 306°; Balava until 00:59 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:01 to 06:01 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: Makara gives Magha. The Sun enters Kumbha on 12 Feb, inside the month. The next new moon, 6 Mar, finds it in Kumbha and begins Phalguna.

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 Mar, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1980, 02:55 Mon. Since then the Sun has moved 344.8° round the stars. Vikram Samvat numbers that year 2037; Shaka Samvat numbers it 1902.
