Panchang in Ipameri, Goiás, Brazil Thu 10 Feb 1994

Mauni Amavasya follows the tithi at sunrise. Amavasya runs from 12:08 on Wed 9 Feb to 12:29 on Thu 10 Feb, so it holds sunrise only on Thu 10 Feb, at 07:04. 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, 07:04 here. Chaturdashi ended at 12:08 Wed, before it. Amavasya ends at 12:29, when the lead reaches 360°. The lead passed 180° at the full moon of 27 Jan, so the Moon is waning: Krishna paksha.

The night of Wed 9 Feb ran from sunset 19:49 Wed to sunrise 07:04, 11 h 15 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:04 to 19:49, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:49 to 07:05 Fri, splits into 8 choghadiyas of 1 h 24 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 1 at 293°20′. It leaves at 05:13 Fri, for Shatabhisha.

Add the Sun's and the Moon's places among the stars: 297.6° + 295° = 592.6°, one full turn and 232.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 20:02, 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 00:15, when the lead reached 354°; Nagava runs until 12:29.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:04 to 07:05 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: Dhanu gives Pausha. The Sun enters Makara on 14 Jan, inside the month. The next new moon, 10 Feb, 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 10 Feb, 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: 23 Mar 1993, 04:14 Tue. Since then the Sun has moved 318.7° round the stars. Vikram Samvat numbers that year 2050; Shaka Samvat numbers it 1915.
