Panchang in Ipameri, Goiás, Brazil Mon 27 Mar 2017

Amavasya follows the tithi at sunrise. Amavasya runs from 02:14 on Mon 27 Mar to 23:57 on Mon 27 Mar, so it holds sunrise only on Mon 27 Mar, at 06:18. 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, 06:18 here. Chaturdashi ended at 02:14, before it. Amavasya ends at 23:57, when the lead reaches 360°. The lead passed 180° at the full moon of 12 Mar, so the Moon is waning: Krishna paksha.

The night of Sun 26 Mar ran from sunset 18:18 Sun to sunrise 06:18, 12 h 0 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:18 to 18:17, 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 night here, 18:17 to 06:18 Tue, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Purva Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 4 at 330°. It leaves at 06:49, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 342.8° + 333° = 675.8°, one full turn and 315.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 306°40′–320°00′ is the 24th, Shukla. It ends at 12:54, then Brahma.

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 13:09, when the lead reaches 354°; Nagava until 23:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:18 to 06:18 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 27 Mar, finds it in Meena and begins Chaitra.

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 27 Mar, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2016, 08:23 Thu. Since then the Sun has moved 348.8° round the stars. Vikram Samvat numbers that year 2073; Shaka Samvat numbers it 1938.
