Panchang in Mapleton, Utah, United States Tue 15 May 2018

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 0°–12° is the 1st, Shukla Pratipada. A day takes the tithi in force at its sunrise, 06:10 here. Amavasya ended at 05:47, before it. Pratipada ends at 02:58 Wed, when the lead reaches 12°. The lead passed 0° at the new moon of 15 May, so the Moon is waxing: Shukla paksha.

The night of Mon 14 May ran from sunset 20:34 Mon to sunrise 06:10, 9 h 36 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:10 to 20:35, splits into 8 choghadiyas of 1 h 48 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:35 to 06:09 Wed, splits into 8 choghadiyas of 1 h 11 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′. Krittika spans 26°40′–40°00′; the Moon entered its pada 2 at 30°. It leaves at 21:28, for Rohini.

Add the Sun's and the Moon's places among the stars: 30.5° + 30.7° = 61.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 14:36, then Atiganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Pratipada is Kinstughna and the second Bava. Kinstughna runs until 16:24, when the lead reaches 6°; Bava until 02:58 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:10 to 06:09 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 05:47 to 13 Jun 13:43 Wed the Sun stayed in Vrishabha, entering Mithuna at 15 Jun 00:06 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, 07:11 Sat. Since then the Sun has moved 57.7° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
