Panchang in Atliaca, Guerrero, Mexico Wed 6 Apr 2016

Amavasya follows the tithi at sunrise. Amavasya begins at 10:06 on Wed 6 Apr, after that sunrise, and ends at 06:23 on Thu 7 Apr, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Wed 6 Apr. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Atliaca

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, 07:27 here. Trayodashi ended at 13:34 Tue, before it. Chaturdashi ends at 10:06, when the lead reaches 348°. The lead passed 180° at the full moon of 23 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 10:06 and ended at 06:23 Thu, between the sunrises of 07:27 and 07:26 Thu. Wednesday reads Chaturdashi and Thursday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Tue 5 Apr ran from sunset 19:51 Tue to sunrise 07:27, 11 h 36 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:27 to 19:52, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:52 to 07:26 Thu, splits into 8 choghadiyas of 1 h 26 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 2 at 336°40′. It leaves at 18:50, for Revati.

Add the Sun's and the Moon's places among the stars: 353.1° + 339.5° = 692.6°, one full turn and 332.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 08:38, then Indra.

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 23:52 Tue, when the lead reached 342°; Shakuni runs until 10:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:27 to 07:26 Thu, so the hours after midnight still belong to Budhawara.

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: Kumbha gives Phalguna. The Sun enters Meena on 13 Mar, inside the month. The next new moon, 7 Apr, finds it in Meena and begins Chaitra.

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 7 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 03:36 Fri. Since then the Sun has moved 377.7° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
