Panchang in Diffa, Niger Sun 16 May 2038

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 06:12 on Sun 16 May to 02:37 on Mon 17 May, so only Sunday’s pradosha (18:28–20:43) falls within it. No text giving Pradosh Vrat’s time was found; pradosha is Tithika’s convention.

Pradosh Vrat: every date in Diffa

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 132°–144° is the 12th, Shukla Dwadashi. A day takes the tithi in force at its sunrise, 05:43 here. Ekadashi ended at 09:32 Sat, before it. Dwadashi ends at 06:12, when the lead reaches 144°. The lead passed 0° at the new moon of 4 May, so the Moon is waxing: Shukla paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 06:12 and ended at 02:37 Mon, between the sunrises of 05:43 and 05:43 Mon. Sunday reads Dwadashi and Monday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Sat 15 May ran from sunset 18:28 Sat 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 Mon, 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′. Chitra spans 173°20′–186°40′; the Moon entered its pada 1 at 173°20′. It leaves at 00:41 Mon, for Swati.

Add the Sun's and the Moon's places among the stars: 31.1° + 174.8° = 205.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 16:59, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Bava and the second Balava. Bava ended at 19:54 Sat, when the lead reached 138°; Balava runs until 06:12.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:43 to 05:43 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: 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: 4 Apr 2038, 17:43 Sun. Since then the Sun has moved 40.5° round the stars. Vikram Samvat numbers that year 2095; Shaka Samvat numbers it 1960.
