Panchang in Ipameri, Goiás, Brazil Sat 13 Nov 1993

Lakshmi Puja is done in pradosha, the 3 muhurtas after sunset. Amavasya runs from 22:51 on Fri 12 Nov to 19:34 on Sat 13 Nov, so it touches only Saturday’s pradosha (19:24–21:37). Every reading takes that day.

Lakshmi Puja muhurat: pradosha, 19:24–21:37. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 19:31 to 21:37.

Diwali: every date in Ipameri

Amavasya follows the tithi at sunrise. Amavasya runs from 22:51 on Fri 12 Nov to 19:34 on Sat 13 Nov, so it holds sunrise only on Sat 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 22:51 Fri, before it. Amavasya ends at 19:34, when the lead reaches 360°. The lead passed 180° at the full moon of 30 Oct, so the Moon is waning: Krishna paksha.

The night of Fri 12 Nov ran from sunset 19:24 Fri 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 19:24, splits into 8 choghadiyas of 1 h 36 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:24 to 06:29 Sun, 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 07:04, for Vishakha.

Add the Sun's and the Moon's places among the stars: 207.2° + 199.6° = 406.8°, one full turn and 46.8°. 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 16:17, 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 09:11, when the lead reaches 354°; Nagava until 19:34.

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

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 17 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: 23 Mar 1993, 04:14 Tue. Since then the Sun has moved 228.3° round the stars. Vikram Samvat numbers that year 2050; Shaka Samvat numbers it 1915.
