Panchang in Diffa, Niger Thu 19 Jan 2023

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 08:48 on Thu 19 Jan to 05:30 on Fri 20 Jan, so only Thursday’s pradosha (18:03–20:34) 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: 312°–324° is the 27th, Krishna Dwadashi. A day takes the tithi in force at its sunrise, 06:36 here. Ekadashi ended at 11:33 Wed, before it. Dwadashi ends at 08:48, when the lead reaches 324°. The lead passed 180° at the full moon of 7 Jan, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Trayodashi began at 08:48 and ended at 05:30 Fri, between the sunrises of 06:36 and 06:36 Fri. Thursday reads Dwadashi and Friday reads Chaturdashi: Trayodashi is a kshaya tithi here.

The night of Wed 18 Jan ran from sunset 18:03 Wed to sunrise 06:36, 12 h 33 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:36 to 18:03, splits into 8 choghadiyas of 1 h 25 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:03 to 06:36 Fri, splits into 8 choghadiyas of 1 h 34 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 4 at 236°40′. It leaves at 10:47, for Mula.

Add the Sun's and the Moon's places among the stars: 274.7° + 237.4° = 512.1°, one full turn and 152.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 18:33, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dwadashi is Kaulava and the second Taitila. Kaulava ended at 22:15 Wed, when the lead reached 318°; Taitila runs until 08:48.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:36 to 06:36 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 21 Jan, finds it in Makara and begins Magha.

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 21 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 1 Apr 2022, 07:24 Fri. Since then the Sun has moved 287.4° round the stars. Vikram Samvat numbers that year 2079; Shaka Samvat numbers it 1944.
