Panchang in Ipameri, Goiás, Brazil Thu 14 Jun 1923

Amavasya follows the tithi at sunrise. Amavasya runs from 08:32 on Wed 13 Jun to 09:41 on Thu 14 Jun, so it holds sunrise only on Thu 14 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 08:32 Wed, before it. Amavasya ends at 09:41, when the lead reaches 360°. The lead passed 180° at the full moon of 30 May, so the Moon is waning: Krishna paksha.

The night of Wed 13 Jun ran from sunset 17:44 Wed to sunrise 06:40, 12 h 56 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 06:40 Fri, 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′. Mrigashira spans 53°20′–66°40′; the Moon entered its pada 2 at 56°40′. It leaves at 23:07, for Ardra.

Add the Sun's and the Moon's places among the stars: 59.5° + 58.1° = 117.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 106°40′–120°00′ is the 9th, Shula. It ends at 10:58, 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 21:10 Wed, when the lead reached 354°; Nagava runs until 09:41.

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

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 May 19:38 Tue to 14 Jun 09:41 the Sun stayed in Vrishabha, entering Mithuna at 14 Jun 18:42, after the new moon. A month with no sankranti is Adhika Jyeshtha, before Jyeshtha 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 Jun, with the Sun in Vrishabha, begins Jyeshtha (Adhik). Until then this Krishna paksha reads Jyeshtha (Adhik) here, and Jyeshtha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 1923, 09:51 Sat. Since then the Sun has moved 86.4° round the stars. Vikram Samvat numbers that year 1980; Shaka Samvat numbers it 1845.
