Panchang in Midleton, Munster, Ireland Fri 6 May 2016

Amavasya follows the tithi at sunrise. Amavasya runs from 00:17 on Fri 6 May to 20:29 on Fri 6 May, so it holds sunrise only on Fri 6 May, at 05:53. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Midleton

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, 05:53 here. Chaturdashi ended at 00:17, before it. Amavasya ends at 20:29, when the lead reaches 360°. The lead passed 180° at the full moon of 22 Apr, so the Moon is waning: Krishna paksha.

The night of Thu 5 May ran from sunset 21:04 Thu to sunrise 05:53, 8 h 49 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:53 to 21:06, splits into 8 choghadiyas of 1 h 54 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:06 to 05:51 Sat, splits into 8 choghadiyas of 1 h 5 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 02:54 Sat, for Krittika.

Add the Sun's and the Moon's places among the stars: 22° + 13.4° = 35.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 26°40′–40°00′ is the 3rd, Ayushmana. It ends at 12:46, then Saubhagya.

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 10:23, when the lead reaches 354°; Nagava until 20:29.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:53 to 05:51 Sat, so the hours after midnight still belong to Shukrawara.

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: Meena gives Chaitra. The Sun enters Mesha on 13 Apr, inside the month. The next new moon, 6 May, finds it in Mesha and begins Vaishakha.

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 6 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 12:23 Thu. Since then the Sun has moved 28° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
