Panchang in Codcod, Western Visayas, Philippines Tue 16 Sep 2031

Amavasya follows the tithi at sunrise. Amavasya runs from 01:53 on Tue 16 Sep to 02:46 on Wed 17 Sep, so it holds sunrise only on Tue 16 Sep, at 05:36. 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, 05:36 here. Chaturdashi ended at 01:53, before it. Amavasya ends at 02:46 Wed, when the lead reaches 360°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

The night of Mon 15 Sep ran from sunset 17:48 Mon to sunrise 05:36, 11 h 48 m. Cut into 15 muhurtas of 47 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:36 to 17:47, splits into 8 choghadiyas of 1 h 31 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:47 to 05:36 Wed, splits into 8 choghadiyas of 1 h 28 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 2 at 136°40′. It leaves at 21:34, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 148.5° + 138.3° = 286.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 17:05, then Shubha.

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 14:23, when the lead reaches 354°; Nagava until 02:46 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:36 to 05:36 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 18 Aug 12:32 Mon to 17 Sep 02:46 Wed the Sun stayed in Simha, entering Kanya at 17 Sep 17:19 Wed, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 17 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2031, 11:49 Sun. Since then the Sun has moved 170.5° round the stars. Vikram Samvat numbers that year 2088; Shaka Samvat numbers it 1953.
