Panchang in Ipameri, Goiás, Brazil Tue 12 May 1953

Amavasya follows the tithi at sunrise. Amavasya runs from 04:33 on Tue 12 May to 02:05 on Wed 13 May, so it holds sunrise only on Tue 12 May, at 06:29. 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, 06:29 here. Chaturdashi ended at 04:33, before it. Amavasya ends at 02:05 Wed, when the lead reaches 360°. The lead passed 180° at the full moon of 29 Apr, so the Moon is waning: Krishna paksha.

The night of Mon 11 May ran from sunset 17:49 Mon to sunrise 06:29, 12 h 40 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 17:48, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:48 to 06:29 Wed, splits into 8 choghadiyas of 1 h 35 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 2 at 16°40′. It leaves at 22:16, for Krittika.

Add the Sun's and the Moon's places among the stars: 28.1° + 17.2° = 45.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 18:57, then Shobhana.

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 15:16, when the lead reaches 354°; Nagava until 02:05 Wed.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:29 Wed, so the hours after midnight still belong to Mangalawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 13 Apr 17:08 Mon to 13 May 02:05 Wed the Sun stayed in Mesha, entering Vrishabha at 14 May 04:41 Thu, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 13 May, with the Sun in Mesha, begins Vaishakha (Adhik). Until then this Krishna paksha reads Vaishakha (Adhik) here, and Vaishakha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 1953, 08:04 Sun. Since then the Sun has moved 56.7° round the stars. Vikram Samvat numbers that year 2010; Shaka Samvat numbers it 1875.
