Panchang in Ipameri, Goiás, Brazil Sun 18 Oct 1914

Lakshmi Puja is done in pradosha, the 3 muhurtas after sunset. Amavasya runs from 07:18 on Sun 18 Oct to 03:33 on Mon 19 Oct, so only Sunday’s pradosha (18:13–20:31) falls within it. Every reading takes that day.

Lakshmi Puja muhurat: pradosha, 18:13–20:31. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 20:11 to 20:31.

Diwali: every date in Ipameri

The abhyanga bath is taken in arunodaya, the 96 minutes before sunrise. Chaturdashi runs from 10:45 on Sat 17 Oct to 07:18 on Sun 18 Oct, so only Sunday’s arunodaya (04:06–05:42) falls within it. No text giving Narak Chaturdashi’s time was found; arunodaya is Tithika’s convention.

Narak Chaturdashi: every date in Ipameri

Amavasya follows the tithi at sunrise. Amavasya begins at 07:18 on Sun 18 Oct, after that sunrise, and ends at 03:33 on Mon 19 Oct, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Sun 18 Oct. 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: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:42 here. Trayodashi ended at 10:45 Sat, before it. Chaturdashi ends at 07:18, when the lead reaches 348°. The lead passed 180° at the full moon of 4 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 07:18 and ended at 03:33 Mon, between the sunrises of 05:42 and 05:41 Mon. Sunday reads Chaturdashi and Monday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Sat 17 Oct ran from sunset 18:13 Sat to sunrise 05:42, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:42 to 18:13, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:13 to 05:41 Mon, splits into 8 choghadiyas of 1 h 26 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′. Hasta spans 160°00′–173°20′; the Moon entered its pada 3 at 166°40′. It leaves at 13:19, for Chitra.

Add the Sun's and the Moon's places among the stars: 181.5° + 168.5° = 350°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 20:34, then Vishkambha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 21:05 Sat, when the lead reached 342°; Shakuni runs until 07:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:42 to 05:41 Mon, so the hours after midnight still belong to Raviwara.

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, 19 Oct, 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 19 Oct, 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: 26 Mar 1914, 15:08 Thu. Since then the Sun has moved 198.9° round the stars. Vikram Samvat numbers that year 1971; Shaka Samvat numbers it 1836.
