Panchang in Diffa, Niger Wed 10 Jun 2037

Shiva’s Pradosh puja is done in pradosha, the 3 muhurtas after sunset. Trayodashi runs from 19:26 on Wed 10 Jun to 19:35 on Thu 11 Jun, touching pradosha on both evenings. The Nirnayasindhu takes the evening it holds more of: Wed 10 Jun. 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, 05:42 here. Ekadashi ended at 18:38 Tue, before it. Dwadashi ends at 19:26, when the lead reaches 324°. The lead passed 180° at the full moon of 29 May, so the Moon is waning: Krishna paksha.

The night of Tue 9 Jun ran from sunset 18:35 Tue to sunrise 05:42, 11 h 7 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 18:36, splits into 8 choghadiyas of 1 h 36 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:36 to 05:42 Thu, splits into 8 choghadiyas of 1 h 23 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′. Ashwini spans 0°00′–13°20′; the Moon entered its pada 4 at 10°. It leaves at 07:06, for Bharani.

Add the Sun's and the Moon's places among the stars: 55.3° + 12.6° = 67.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 66°40′–80°00′ is the 6th, Atiganda. It ends at 03:00 Thu, then Sukarma.

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 runs until 07:07, when the lead reaches 318°; Taitila until 19:26.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:42 to 05:42 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 06:54 Fri to 13 Jun 18:10 Sat the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 04:02 Mon, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha itself.

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 13 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2037, 00:36 Tue. Since then the Sun has moved 83° round the stars. Vikram Samvat numbers that year 2094; Shaka Samvat numbers it 1959.
