Panchang in Ipameri, Goiás, Brazil Mon 15 Jan 1934

Mauni Amavasya follows the tithi at sunrise. Amavasya runs from 14:21 on Sun 14 Jan to 10:37 on Mon 15 Jan, so it holds sunrise only on Mon 15 Jan, at 05:49. 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, 05:49 here. Chaturdashi ended at 14:21 Sun, before it. Amavasya ends at 10:37, when the lead reaches 360°. The lead passed 180° at the full moon of 31 Dec, so the Moon is waning: Krishna paksha.

The night of Sun 14 Jan ran from sunset 18:54 Sun to sunrise 05:49, 10 h 55 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:49 to 18:54, splits into 8 choghadiyas of 1 h 38 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 05:50 Tue, 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 1 at 266°40′. It leaves at 23:35, for Shravana.

Add the Sun's and the Moon's places among the stars: 271.6° + 268.8° = 540.4°, one full turn and 180.4°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 15:09, then Vajra.

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 00:28, when the lead reached 354°; Nagava runs until 10:37.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:49 to 05:50 Tue, so the hours after midnight still belong to Somawara.

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 13 Jan, inside the month. The next new moon, 15 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 15 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: 26 Mar 1933, 01:20 Sun. Since then the Sun has moved 289.5° round the stars. Vikram Samvat numbers that year 1990; Shaka Samvat numbers it 1855.
