Panchang in Diffa, Niger Fri 27 Dec 2013

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 06:30 here. Navami ended at 03:11, before it. Dashami ends at 02:25 Sat, when the lead reaches 300°. The lead passed 180° at the full moon of 17 Dec, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 07:12, came before Navami ended at 07:41: this day reads Navami. Dashami ends at 06:55 Sat, before the next sunrise, so no day here reads Dashami: it is kshaya.

Sunrise here, 06:30, came after Navami ended at 03:11: this day reads Dashami.

The night of Thu 26 Dec ran from sunset 17:50 Thu to sunrise 06:30, 12 h 40 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:30 to 17:51, 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, 17:51 to 06:30 Sat, 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 16:15, for Swati.

Add the Sun's and the Moon's places among the stars: 251.6° + 181.2° = 432.8°, one full turn and 72.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 18:30, then Sukarma.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija runs until 14:55, when the lead reaches 294°; Vishti until 02:25 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:30 to 06:30 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: Vrishchika gives Margashirsha. The Sun enters Dhanu on 15 Dec, inside the month. The next new moon, 1 Jan, 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 1 Jan, 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: 10 Apr 2013, 10:35 Wed. Since then the Sun has moved 255° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
