Panchang in Diffa, Niger Sun 17 Mar 2013

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 06:15 here. Panchami ended at 00:10, before it. Shashthi ends at 02:33 Mon, when the lead reaches 72°. The lead passed 0° at the new moon of 11 Mar, so the Moon is waxing: Shukla paksha.

The night of Sat 16 Mar ran from sunset 18:20 Sat to sunrise 06:15, 11 h 55 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:15 to 18:20, 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 night here, 18:20 to 06:15 Mon, 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 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 3 at 33°20′. It leaves at 15:17, for Rohini.

Add the Sun's and the Moon's places among the stars: 332.7° + 35.5° = 368.2°, one full turn and 8.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 15:42, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava runs until 13:19, when the lead reaches 66°; Taitila until 02:33 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:15 Mon, so the hours after midnight still belong to Raviwara.

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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 10 Apr, finds it in Meena and begins Chaitra.

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 11 Mar, with the Sun in Kumbha, began Phalguna. This Shukla paksha reads Phalguna in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 15:37 Thu. Since then the Sun has moved 354.4° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
