Panchang in Mapleton, Utah, United States Thu 29 Aug 2019

Amavasya follows the tithi at sunrise. Amavasya begins at 08:25 on Thu 29 Aug, after that sunrise, and ends at 04:37 on Fri 30 Aug, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Thu 29 Aug. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Mapleton

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 06:51 here. Trayodashi ended at 11:58 Wed, before it. Chaturdashi ends at 08:25, when the lead reaches 348°. The lead passed 180° at the full moon of 15 Aug, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 08:25 and ended at 04:37 Fri, between the sunrises of 06:51 and 06:52 Fri. Thursday reads Chaturdashi and Friday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Wed 28 Aug ran from sunset 20:04 Wed to sunrise 06:51, 10 h 47 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:51 to 20:02, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:02 to 06:52 Fri, splits into 8 choghadiyas of 1 h 21 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 4 at 116°40′. It leaves at 08:40, for Magha.

Add the Sun's and the Moon's places among the stars: 131.8° + 118.8° = 250.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 10:53, then Shiva.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 22:14 Wed, when the lead reached 342°; Shakuni runs until 08:25.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:51 to 06:52 Fri, so the hours after midnight still belong to Guruwara.

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: Karka gives Shravana. The Sun enters Simha on 17 Aug, inside the month. The next new moon, 30 Aug, finds it in Simha and begins Bhadrapada.

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 30 Aug, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 5 Apr 2019, 02:50 Fri. Since then the Sun has moved 140.6° round the stars. Vikram Samvat numbers that year 2076; Shaka Samvat numbers it 1941.
