Panchang in Ipameri, Goiás, Brazil Sat 13 Apr 2086

Amavasya follows the tithi at sunrise. Amavasya runs from 17:32 on Fri 12 Apr to 13:54 on Sat 13 Apr, so it holds sunrise only on Sat 13 Apr, at 06:21. 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, 06:21 here. Chaturdashi ended at 17:32 Fri, before it. Amavasya ends at 13:54, when the lead reaches 360°. The lead passed 180° at the full moon of 30 Mar, so the Moon is waning: Krishna paksha.

The night of Fri 12 Apr ran from sunset 18:05 Fri to sunrise 06:21, 12 h 16 m. Cut into 15 muhurtas of 49 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:21 to 18:04, splits into 8 choghadiyas of 1 h 27 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:04 to 06:21 Sun, splits into 8 choghadiyas of 1 h 32 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 3 at 353°20′. It leaves at 15:13, for Ashwini.

Add the Sun's and the Moon's places among the stars: 358.9° + 354.4° = 713.3°, one full turn and 353.3°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 16:22, then Vishkambha.

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 03:42, when the lead reached 354°; Nagava runs until 13:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:21 to 06:21 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 15 Mar 05:05 Fri to 13 Apr 13:54 the Sun stayed in Meena, entering Mesha at 14 Apr 10:05 Sun, after the new moon. A month with no sankranti is Adhika Chaitra, before Chaitra 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 Apr, with the Sun in Meena, begins Chaitra (Adhik). Until then this Krishna paksha reads Chaitra (Adhik) here, and Chaitra (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 15 Mar 2086, 05:05 Fri. Since then the Sun has moved 28.8° round the stars. Vikram Samvat numbers that year 2143; Shaka Samvat numbers it 2008.
