Panchang in Codcod, Western Visayas, Philippines Tue 19 Jun 2012

Amavasya follows the tithi at sunrise. Amavasya runs from 21:03 on Mon 18 Jun to 23:02 on Tue 19 Jun, so it holds sunrise only on Tue 19 Jun, at 05:26. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 05:26 here. Chaturdashi ended at 21:03 Mon, before it. Amavasya ends at 23:02, when the lead reaches 360°. The lead passed 180° at the full moon of 4 Jun, so the Moon is waning: Krishna paksha.

The night of Mon 18 Jun ran from sunset 18:10 Mon to sunrise 05:26, 11 h 16 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:26 to 18:10, 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, 18:10 to 05:26 Wed, 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 1 at 53°20′. It leaves at 02:56 Wed, for Ardra.

Add the Sun's and the Moon's places among the stars: 64° + 55.8° = 119.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 05:45, then Ganda.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada runs until 10:05, when the lead reaches 354°; Nagava until 23:02.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:26 to 05:26 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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 19 Jun, finds it in Mithuna and begins Ashadha.

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 19 Jun, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 22:37 Thu. Since then the Sun has moved 85.7° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
