Panchang in Diffa, Niger Fri 17 May 2019

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, 05:43 here. Trayodashi ended at 01:34, before it. Chaturdashi ends at 23:41, when the lead reaches 168°. The lead passed 0° at the new moon of 4 May, so the Moon is waxing: Shukla paksha.

Sunrise here, 05:29, came before Trayodashi ended at 06:04: this day reads Trayodashi. Chaturdashi ends at 04:11 Sat, before the next sunrise, so no day here reads Chaturdashi: it is kshaya.

The night of Thu 16 May ran from sunset 18:28 Thu to sunrise 05:43, 11 h 15 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:43 to 18:28, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:28 to 05:43 Sat, splits into 8 choghadiyas of 1 h 24 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 2 at 190°. It leaves at 22:37, for Vishakha.

Add the Sun's and the Moon's places among the stars: 31.9° + 190.2° = 222.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 13:06, then Variyana.

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 runs until 12:35, when the lead reaches 162°; Vanija until 23:41.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:43 to 05:43 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: Mesha gives Vaishakha. The Sun enters Vrishabha on 15 May, inside the month. The next new moon, 3 Jun, finds it in Vrishabha and begins Jyeshtha.

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 May, with the Sun in Mesha, began Vaishakha. This Shukla paksha reads Vaishakha in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 2019, 09:50 Fri. Since then the Sun has moved 40.7° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
