Panchang in Codcod, Western Visayas, Philippines Fri 13 Apr 2029

Amavasya follows the tithi at sunrise. Amavasya holds both sunrises, 05:37 on Fri 13 Apr and 05:37 on Sat 14 Apr. Over two sunrises the Nirnayasindhu takes the first: Fri 13 Apr. 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, 05:37 here. Chaturdashi ended at 03:12, before it. Amavasya ends at 05:40 Sat, when the lead reaches 360°. The lead passed 180° at the full moon of 30 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 03:12, before sunrise at 05:37, and ends at 05:40 Sat, after the next sunrise at 05:37 Sat. Both days read Amavasya: it is a vriddhi tithi here.

The night of Thu 12 Apr ran from sunset 17:57 Thu to sunrise 05:37, 11 h 40 m. Cut into 15 muhurtas of 46 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 17:58, splits into 8 choghadiyas of 1 h 32 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:58 to 05:37 Sat, splits into 8 choghadiyas of 1 h 27 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 1 at 346°40′. It leaves at 05:43 Sat, for Ashwini.

Add the Sun's and the Moon's places among the stars: 359° + 348.1° = 707.1°, one full turn and 347.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 05:46 Sat, then Vishkambha.

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 16:26, when the lead reaches 354°; Nagava until 05:40 Sat.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:37 Sat, so the hours after midnight still belong to Shukrawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Mar 12:19 Thu to 14 Apr 05:40 Sat the Sun stayed in Meena, entering Mesha at 14 Apr 06:24 Sat, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra 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 14 Apr, with the Sun in Meena, begins Chaitra (Adhik). Until then this Krishna paksha reads Chaitra (Adhik) here, and Chaitra (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 2029, 12:19 Thu. Since then the Sun has moved 28.4° round the stars. Vikram Samvat numbers that year 2086; Shaka Samvat numbers it 1951.
