Panchang in Ipameri, Goiás, Brazil Sun 23 Jan 1955

Mauni Amavasya follows the tithi at sunrise. Amavasya runs from 21:25 on Sat 22 Jan to 22:06 on Sun 23 Jan, so it holds sunrise only on Sun 23 Jan, at 05:54. No text giving Mauni 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, 05:54 here. Chaturdashi ended at 21:25 Sat, before it. Amavasya ends at 22:06, when the lead reaches 360°. The lead passed 180° at the full moon of 8 Jan, so the Moon is waning: Krishna paksha.

The night of Sat 22 Jan ran from sunset 18:54 Sat to sunrise 05:54, 11 h 0 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:54 to 18:54, splits into 8 choghadiyas of 1 h 37 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:54 to 05:55 Mon, splits into 8 choghadiyas of 1 h 22 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′. Uttara Ashadha spans 266°40′–280°00′; the Moon entered its pada 2 at 270°. It leaves at 22:02, for Shravana.

Add the Sun's and the Moon's places among the stars: 279.3° + 271.4° = 550.7°, one full turn and 190.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 186°40′–200°00′ is the 15th, Vajra. It ends at 21:59, then Siddhi.

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 09:50, when the lead reaches 354°; Nagava until 22:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:54 to 05:55 Mon, so the hours after midnight still belong to Raviwara.

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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 23 Jan, finds it in Makara and begins Magha.

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 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 3 Apr 1954, 09:24 Sat. Since then the Sun has moved 289.3° round the stars. Vikram Samvat numbers that year 2011; Shaka Samvat numbers it 1876.
