Panchang in Ipameri, Goiás, Brazil Wed 15 Jul 2015

Amavasya follows the tithi at sunrise. Amavasya runs from 22:08 on Tue 14 Jul to 22:24 on Wed 15 Jul, so it holds sunrise only on Wed 15 Jul, at 06:43. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Ipameri

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, 06:43 here. Chaturdashi ended at 22:08 Tue, before it. Amavasya ends at 22:24, when the lead reaches 360°. The lead passed 180° at the full moon of 1 Jul, so the Moon is waning: Krishna paksha.

The night of Tue 14 Jul ran from sunset 17:53 Tue to sunrise 06:43, 12 h 50 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:43 to 17:53, splits into 8 choghadiyas of 1 h 23 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:53 to 06:43 Thu, splits into 8 choghadiyas of 1 h 36 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 1 at 80°. It leaves at 06:18 Thu, for Pushya.

Add the Sun's and the Moon's places among the stars: 88.5° + 80.8° = 169.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 160°00′–173°20′ is the 13th, Vyaghata. It ends at 13:40, then Harshana.

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 10:12, when the lead reaches 354°; Nagava until 22:24.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:43 to 06:43 Thu, so the hours after midnight still belong to Budhawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 16 Jun 11:05 Tue to 15 Jul 22:24 the Sun stayed in Mithuna, entering Karka at 16 Jul 19:32 Thu, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 15 Jul, with the Sun in Mithuna, begins Ashadha (Adhik). Until then this Krishna paksha reads Ashadha (Adhik) here, and Ashadha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 20 Mar 2015, 06:36 Fri. Since then the Sun has moved 113.1° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
