Panchang in Diffa, Niger Mon 28 Aug 2023

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 13:53 on Mon 28 Aug to 10:18 on Tue 29 Aug, so only Monday’s pradosha (18:23–20:42) 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, 05:58 here. Ekadashi ended at 17:03 Sun, before it. Dwadashi ends at 13:53, when the lead reaches 144°. The lead passed 0° at the new moon of 16 Aug, so the Moon is waxing: Shukla paksha.

The night of Sun 27 Aug ran from sunset 18:24 Sun to sunrise 05:58, 11 h 34 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:58 to 18:23, 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, 18:23 to 05:58 Tue, 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 1 at 266°40′. It leaves at 22:13, for Shravana.

Add the Sun's and the Moon's places among the stars: 130.5° + 269.9° = 400.4°, one full turn and 40.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 01:31 Tue, then Shobhana.

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 03:31, when the lead reached 138°; Balava runs until 13:53.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:58 to 05:58 Tue, so the hours after midnight still belong to Somawara.

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, 15 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 16 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: 21 Mar 2023, 18:23 Tue. Since then the Sun has moved 153.9° round the stars. Vikram Samvat numbers that year 2080; Shaka Samvat numbers it 1945.
