Panchang in Diffa, Niger Wed 13 Dec 2017

Smartas test Ekadashi at sunrise: it holds sunrise on Wed 13 Dec only, at 06:23: Wed 13 Dec. Vaishnavas test arunodaya: Dashami ended at 21:38 Tue, before it (04:47–06:23).

Saphala Ekadashi: every date in Diffa

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, 06:23 here. Dashami ended at 21:38 Tue, before it. Ekadashi ends at 22:55, when the lead reaches 312°. The lead passed 180° at the full moon of 3 Dec, so the Moon is waning: Krishna paksha.

The night of Tue 12 Dec ran from sunset 17:44 Tue to sunrise 06:23, 12 h 39 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:23 to 17:44, 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 night here, 17:44 to 06:23 Thu, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Chitra spans 173°20′–186°40′; the Moon entered its pada 3 at 180°. It leaves at 16:28, for Swati.

Add the Sun's and the Moon's places among the stars: 237.3° + 181.5° = 418.8°, one full turn and 58.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 20:35, then Atiganda.

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 10:13, when the lead reaches 306°; Balava until 22:55.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:23 to 06:23 Thu, so the hours after midnight still belong to Budhawara.

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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 18 Dec, finds it in Dhanu and begins Pausha.

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 18 Dec, with the Sun in Dhanu, begins Pausha. Until then this Krishna paksha reads Pausha here, and Margashirsha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 28 Mar 2017, 03:57 Tue. Since then the Sun has moved 253.8° round the stars. Vikram Samvat numbers that year 2074; Shaka Samvat numbers it 1939.
