Panchang in Diffa, Niger Sat 11 Jan 2014

Smartas test Ekadashi at sunrise: it holds sunrise on Sat 11 Jan only, at 06:35: Sat 11 Jan. Vaishnavas test arunodaya: Dashami ended at 18:34 Fri, before it (04:59–06:35).

Pausha Putrada Ekadashi: every date in Diffa

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 120°–132° is the 11th, Shukla Ekadashi. A day takes the tithi in force at its sunrise, 06:35 here. Dashami ended at 18:34 Fri, before it. Ekadashi ends at 20:20, when the lead reaches 132°. The lead passed 0° at the new moon of 1 Jan, so the Moon is waxing: Shukla paksha.

The night of Fri 10 Jan ran from sunset 17:59 Fri to sunrise 06:35, 12 h 36 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:35 to 17:59, 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, 17:59 to 06:35 Sun, 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 2 at 30°. It leaves at 21:27, for Rohini.

Add the Sun's and the Moon's places among the stars: 266.9° + 32.5° = 299.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 19:57, then Shukla.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Ekadashi is Vanija and the second Vishti. Vanija runs until 07:24, when the lead reaches 126°; Vishti until 20:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:35 to 06:35 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, 30 Jan, 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 1 Jan, with the Sun in Dhanu, began Pausha. This Shukla paksha reads Pausha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2013, 10:35 Wed. Since then the Sun has moved 270.3° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
