Panchang in Ipameri, Goiás, Brazil Tue 16 Sep 2031

Amavasya follows the tithi at sunrise. Amavasya runs from 14:53 on Mon 15 Sep to 15:46 on Tue 16 Sep, so it holds sunrise only on Tue 16 Sep, at 06:07. 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, 06:07 here. Chaturdashi ended at 14:53 Mon, before it. Amavasya ends at 15:46, when the lead reaches 360°. The lead passed 180° at the full moon of 1 Sep, so the Moon is waning: Krishna paksha.

The night of Mon 15 Sep ran from sunset 18:07 Mon to sunrise 06:07, 12 h 0 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:07 to 18:07, splits into 8 choghadiyas of 1 h 30 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 06:06 Wed, splits into 8 choghadiyas of 1 h 29 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 4 at 143°20′. It leaves at 10:34, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 149° + 144.4° = 293.4°. The sum, cut into 27 parts of 13°20′, gives the yoga: 293°20′–306°40′ is the 23rd, Shubha. It ends at 05:33 Wed, then Shukla.

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 03:23, when the lead reached 354°; Nagava runs until 15:46.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:07 to 06:06 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 18 Aug 01:32 Mon to 16 Sep 15:46 the Sun stayed in Simha, entering Kanya at 17 Sep 06:19 Wed, after the new moon. A month with no sankranti is Adhika Bhadrapada, before Bhadrapada 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 Sep, with the Sun in Simha, begins Bhadrapada (Adhik). Until then this Krishna paksha reads Bhadrapada (Adhik) here, and Bhadrapada (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 23 Mar 2031, 00:49 Sun. Since then the Sun has moved 171° round the stars. Vikram Samvat numbers that year 2088; Shaka Samvat numbers it 1953.
