Panchang in Diffa, Niger Thu 18 Nov 2021

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 156°–168° is the 14th, Shukla Chaturdashi. A day takes the tithi in force at its sunrise, 06:10 here. Trayodashi ended at 05:20 Wed, before it. Chaturdashi ends at 07:30, when the lead reaches 168°. The lead passed 0° at the new moon of 4 Nov, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 05:20 Wed, before sunrise at 06:09 Wed, and ends at 07:30, after the next sunrise at 06:10. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Wed 17 Nov ran from sunset 17:39 Wed to sunrise 06:10, 12 h 31 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 17:39, 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 night here, 17:39 to 06:10 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Bharani spans 13°20′–26°40′; the Moon entered its pada 2 at 16°40′. It leaves at 20:59, for Krittika.

Add the Sun's and the Moon's places among the stars: 211.9° + 19.3° = 231.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 22:28, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Garaja and the second Vanija. Garaja ended at 18:23 Wed, when the lead reached 162°; Vanija runs until 07:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:10 Fri, so the hours after midnight still belong to Guruwara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 4 Dec, finds it in Vrishchika and begins Margashirsha.

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 4 Nov, with the Sun in Tula, began Kartika. This Shukla paksha reads Kartika in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 2021, 03:30 Mon. Since then the Sun has moved 213.6° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
