Panchang in Codcod, Western Visayas, Philippines Mon 17 Oct 2039

Amavasya follows the tithi at sunrise. Amavasya runs from 05:30 on Mon 17 Oct to 03:09 on Tue 18 Oct, so it holds sunrise only on Mon 17 Oct, 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 05:30, before it. Amavasya ends at 03:09 Tue, when the lead reaches 360°. The lead passed 180° at the full moon of 2 Oct, so the Moon is waning: Krishna paksha.

The night of Sun 16 Oct ran from sunset 17:29 Sun to sunrise 05:36, 12 h 7 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:36 to 17:29, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:29 to 05:36 Tue, splits into 8 choghadiyas of 1 h 30 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 3 at 166°40′. It leaves at 16:14, for Chitra.

Add the Sun's and the Moon's places among the stars: 179° + 167° = 346°. The sum, cut into 27 parts of 13°20′, gives the yoga: 333°20′–346°40′ is the 26th, Indra. It ends at 06:39, then Vaidhriti.

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 16:22, when the lead reaches 354°; Nagava until 03:09 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:36 to 05:36 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Sep 16:23 Sun to 18 Oct 03:09 Tue the Sun stayed in Kanya, entering Tula at 18 Oct 06:25 Tue, after the new moon. A month with no sankranti is Adhika Ashwina, before Ashwina 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 18 Oct, with the Sun in Kanya, begins Ashwina (Adhik). Until then this Krishna paksha reads Ashwina (Adhik) here, and Ashwina (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 2039, 01:59 Fri. Since then the Sun has moved 199.5° round the stars. Vikram Samvat numbers that year 2096; Shaka Samvat numbers it 1961.
