Panchang in Diffa, Niger Sun 20 May 2018

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 60°–72° is the 6th, Shukla Shashthi. A day takes the tithi in force at its sunrise, 05:42 here. Panchami ended at 22:14 Sat, before it. Shashthi ends at 19:48, when the lead reaches 72°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

The night of Sat 19 May ran from sunset 18:29 Sat to sunrise 05:42, 11 h 13 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 18:29, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:29 to 05:42 Mon, splits into 8 choghadiyas of 1 h 24 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′. Pushya spans 93°20′–106°40′; the Moon entered its pada 2 at 96°40′. It leaves at 18:14, for Ashlesha.

Add the Sun's and the Moon's places among the stars: 35° + 99.2° = 134.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 133°20′–146°40′ is the 11th, Vriddhi. It ends at 01:19 Mon, then Dhruva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Shashthi is Kaulava and the second Taitila. Kaulava runs until 08:58, when the lead reaches 66°; Taitila until 19:48.

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

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 12:47 Tue to 13 Jun 20:43 Wed the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 07:06 Fri, 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 15 May, with the Sun in Vrishabha, began Jyeshtha (Adhik). This Shukla paksha reads Jyeshtha (Adhik) in both counts.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 14:11 Sat. Since then the Sun has moved 62.2° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
