Panchang in Ipameri, Goiás, Brazil Tue 13 Nov 2012

Lakshmi Puja is done in pradosha, the 3 muhurtas after sunset. Amavasya runs from 23:43 on Mon 12 Nov to 20:08 on Tue 13 Nov, so it touches only Tuesday’s pradosha (19:25–21:37). Every reading takes that day.

Lakshmi Puja muhurat: pradosha, 19:25–21:37. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 19:30 to 21:37.

Amavasya follows the tithi at sunrise. Amavasya runs from 23:43 on Mon 12 Nov to 20:08 on Tue 13 Nov, so it holds sunrise only on Tue 13 Nov, at 06:29. 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, 06:29 here. Chaturdashi ended at 23:43 Mon, before it. Amavasya ends at 20:08, when the lead reaches 360°. The lead passed 180° at the full moon of 29 Oct, so the Moon is waning: Krishna paksha.

Sunrise here, 06:42, came before Chaturdashi ended at 07:13: this day reads Chaturdashi. Amavasya ends at 03:38 Wed, before the next sunrise, so no day here reads Amavasya: it is kshaya.

Sunrise here, 06:29, came after Chaturdashi ended at 23:43 Mon: this day reads Amavasya.

The night of Mon 12 Nov ran from sunset 19:24 Mon to sunrise 06:29, 11 h 5 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:29 to 19:25, 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, 19:25 to 06:29 Wed, splits into 8 choghadiyas of 1 h 23 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′. Swati spans 186°40′–200°00′; the Moon entered its pada 4 at 196°40′. It leaves at 07:36, for Vishakha.

Add the Sun's and the Moon's places among the stars: 207.3° + 199.3° = 406.6°, one full turn and 46.6°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 16:28, then Shobhana.

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 09:57, when the lead reaches 354°; Nagava until 20:08.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:29 to 06:29 Wed, so the hours after midnight still belong to Mangalawara.

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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 13 Nov, finds it in Tula and begins Kartika.

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 13 Nov, with the Sun in Tula, begins Kartika. Until then this Krishna paksha reads Kartika here, and Ashwina in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 22 Mar 2012, 11:37 Thu. Since then the Sun has moved 229° round the stars. Vikram Samvat numbers that year 2069; Shaka Samvat numbers it 1934.
