Panchang in Ipameri, Goiás, Brazil Mon 26 Oct 1981

Lakshmi Puja is done in pradosha, the 3 muhurtas after sunset. Amavasya runs from 15:20 on Mon 26 Oct to 17:13 on Tue 27 Oct, so only Monday’s pradosha (18:16–20:32) falls within it. Every reading takes that day.

Lakshmi Puja muhurat: pradosha, 18:16–20:32. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 19:41 to 20:32.

Diwali: every date in Ipameri

The abhyanga bath is taken in arunodaya, the 96 minutes before sunrise. Chaturdashi runs from 13:47 on Sun 25 Oct to 15:20 on Mon 26 Oct, so only Monday’s arunodaya (04:01–05:37) falls within it. No text giving Narak Chaturdashi’s time was found; arunodaya is Tithika’s convention.

Narak Chaturdashi: 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, 05:37 here. Trayodashi ended at 13:47 Sun, before it. Chaturdashi ends at 15:20, when the lead reaches 348°. The lead passed 180° at the full moon of 13 Oct, so the Moon is waning: Krishna paksha.

The night of Sun 25 Oct ran from sunset 18:16 Sun to sunrise 05:37, 11 h 21 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 18:16, splits into 8 choghadiyas of 1 h 34 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:16 to 05:36 Tue, splits into 8 choghadiyas of 1 h 25 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 4 at 170°. It leaves at 06:51, for Chitra.

Add the Sun's and the Moon's places among the stars: 189.2° + 172.7° = 361.9°, one full turn and 1.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 0°00′–13°20′ is the 1st, Vishkambha. It ends at 02:20 Tue, then Priti.

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 02:31, when the lead reached 342°; Shakuni runs until 15:20.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:36 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: Kanya gives Ashwina. The Sun enters Tula on 16 Oct, inside the month. The next new moon, 27 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 27 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: 4 Apr 1981, 17:19 Sat. Since then the Sun has moved 197.8° round the stars. Vikram Samvat numbers that year 2038; Shaka Samvat numbers it 1903.
