Panchang in Diffa, Niger Fri 21 Aug 2015

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, 05:57 here. Panchami ended at 03:56 Thu, before it. Shashthi ends at 06:10, when the lead reaches 72°. The lead passed 0° at the new moon of 14 Aug, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Shashthi began at 03:56 Thu, before sunrise at 05:57 Thu, and ends at 06:10, after the next sunrise at 05:57. Both days read Shashthi: it is a vriddhi tithi here.

The night of Thu 20 Aug ran from sunset 18:28 Thu to sunrise 05:57, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:57 to 18:27, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:27 to 05:57 Sat, splits into 8 choghadiyas of 1 h 26 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 3 at 193°20′. It leaves at 14:34, for Vishakha.

Add the Sun's and the Moon's places among the stars: 123.8° + 195.7° = 319.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 06:59, then Brahma.

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 ended at 17:06 Thu, when the lead reached 66°; Taitila runs until 06:10.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:57 to 05:57 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: Karka gives Shravana. The Sun enters Simha on 17 Aug, inside the month. The next new moon, 13 Sep, finds it in Simha and begins Bhadrapada.

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 14 Aug, with the Sun in Karka, began Shravana. This Shukla paksha reads Shravana in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 10:36 Fri. Since then the Sun has moved 148.4° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
