Panchang in Diffa, Niger Tue 28 May 2019

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 276°–288° is the 24th, Krishna Navami. A day takes the tithi in force at its sunrise, 05:41 here. Ashtami ended at 06:46 Mon, before it. Navami ends at 09:01, when the lead reaches 288°. The lead passed 180° at the full moon of 18 May, so the Moon is waning: Krishna paksha.

The night of Mon 27 May ran from sunset 18:31 Mon to sunrise 05:41, 11 h 10 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:41 to 18:31, 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, 18:31 to 05:41 Wed, 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′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 3 at 326°40′. It leaves at 14:28, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 42.5° + 328.9° = 371.4°, one full turn and 11.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 09:15, then Priti.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Navami is Taitila and the second Garaja. Taitila ended at 19:56 Mon, when the lead reached 282°; Garaja runs until 09:01.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:41 to 05:41 Wed, so the hours after midnight still belong to Mangalawara.

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 3 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: 5 Apr 2019, 09:50 Fri. Since then the Sun has moved 51.3° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
