Panchang in Diffa, Niger Fri 4 Jun 2021

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 288°–300° is the 25th, Krishna Dashami. A day takes the tithi in force at its sunrise, 05:41 here. Navami ended at 21:52 Thu, before it. Dashami ends at 23:37, when the lead reaches 300°. The lead passed 180° at the full moon of 26 May, so the Moon is waning: Krishna paksha.

The night of Thu 3 Jun ran from sunset 18:33 Thu to sunrise 05:41, 11 h 8 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:41 to 18:34, 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, 18:34 to 05:41 Sat, 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 3 at 340°. It leaves at 16:16, for Revati.

Add the Sun's and the Moon's places among the stars: 49.6° + 341.3° = 390.9°, one full turn and 30.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 22:18, then Saubhagya.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Dashami is Vanija and the second Vishti. Vanija runs until 10:41, when the lead reaches 294°; Vishti until 23:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:41 to 05:41 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 14 May, inside the month. The next new moon, 10 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 10 Jun, with the Sun in Vrishabha, begins Jyeshtha. Until then this Krishna paksha reads Jyeshtha here, and Vaishakha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 12 Apr 2021, 03:30 Mon. Since then the Sun has moved 51.3° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
