Panchang in Ipameri, Goiás, Brazil Sat 16 Aug 1947

Amavasya follows the tithi at sunrise. Amavasya runs from 11:50 on Fri 15 Aug to 08:12 on Sat 16 Aug, so it holds sunrise only on Sat 16 Aug, at 06:31. 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, 06:31 here. Chaturdashi ended at 11:50 Fri, before it. Amavasya ends at 08:12, when the lead reaches 360°. The lead passed 180° at the full moon of 1 Aug, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 08:12 and ended at 04:45 Sun, between the sunrises of 06:31 and 06:31 Sun. Saturday reads Amavasya and Sunday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Fri 15 Aug ran from sunset 18:02 Fri to sunrise 06:31, 12 h 29 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:31 to 18:02, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:02 to 06:31 Sun, splits into 8 choghadiyas of 1 h 33 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 4 at 116°40′. It leaves at 08:48, for Magha.

Add the Sun's and the Moon's places among the stars: 119.6° + 118.6° = 238.2°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 09:20, then Parigha.

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 22:00 Fri, when the lead reached 354°; Nagava runs until 08:12.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:31 to 06:31 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 18 Jul 01:15 Fri to 16 Aug 08:12 the Sun stayed in Karka, entering Simha at 16 Aug 17:42, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana 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 16 Aug, with the Sun in Karka, begins Shravana (Adhik). Until then this Krishna paksha reads Shravana (Adhik) here, and Shravana (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 1947, 13:34 Sat. Since then the Sun has moved 141.5° round the stars. Vikram Samvat numbers that year 2004; Shaka Samvat numbers it 1869.
