Panchang in Ipameri, Goiás, Brazil Thu 15 Jun 1950

Amavasya follows the tithi at sunrise. Amavasya runs from 11:01 on Wed 14 Jun to 12:52 on Thu 15 Jun, so it holds sunrise only on Thu 15 Jun, at 06:40. 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, 06:40 here. Chaturdashi ended at 11:01 Wed, before it. Amavasya ends at 12:52, when the lead reaches 360°. The lead passed 180° at the full moon of 31 May, so the Moon is waning: Krishna paksha.

The night of Wed 14 Jun ran from sunset 17:45 Wed to sunrise 06:40, 12 h 55 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:40 to 17:45, 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, 17:45 to 06:41 Fri, splits into 8 choghadiyas of 1 h 37 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 2 at 56°40′. It leaves at 00:25 Fri, for Ardra.

Add the Sun's and the Moon's places among the stars: 60.6° + 57.7° = 118.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 09:57, then Ganda.

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 ended at 23:59 Wed, when the lead reached 354°; Nagava runs until 12:52.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:40 to 06:41 Fri, so the hours after midnight still belong to Guruwara.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 14 Jun, inside the month. The next new moon, 15 Jun, finds it in Mithuna and begins Ashadha.

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 Jun, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1950, 13:20 Sat. Since then the Sun has moved 86.3° round the stars. Vikram Samvat numbers that year 2007; Shaka Samvat numbers it 1872.
