Panchang in Ipameri, Goiás, Brazil Thu 23 Feb 2096

Amavasya follows the tithi at sunrise. Amavasya runs from 21:46 on Wed 22 Feb to 19:30 on Thu 23 Feb, so it holds sunrise only on Thu 23 Feb, at 06:09. 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, 06:09 here. Chaturdashi ended at 21:46 Wed, before it. Amavasya ends at 19:30, when the lead reaches 360°. The lead passed 180° at the full moon of 8 Feb, so the Moon is waning: Krishna paksha.

The night of Wed 22 Feb ran from sunset 18:42 Wed to sunrise 06:09, 11 h 27 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:09 to 18:41, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:41 to 06:10 Fri, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Dhanishtha spans 293°20′–306°40′; the Moon entered its pada 3 at 300°. It leaves at 13:42, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 309.6° + 302.2° = 611.8°, one full turn and 251.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 240°00′–253°20′ is the 19th, Parigha. It ends at 08:39, then Shiva.

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 08:42, when the lead reaches 354°; Nagava until 19:30.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:09 to 06:10 Fri, so the hours after midnight still belong to Guruwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Makara gives Magha. The Sun enters Kumbha on 13 Feb, inside the month. The next new moon, 23 Feb, finds it in Kumbha and begins Phalguna.

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 23 Feb, with the Sun in Kumbha, begins Phalguna. Until then this Krishna paksha reads Phalguna here, and Magha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 4 Apr 2095, 13:37 Mon. Since then the Sun has moved 319.6° round the stars. Vikram Samvat numbers that year 2152; Shaka Samvat numbers it 2017.
