Panchang in Chahārbāgh, Alborz Province, Iran Sat 22 Oct 2033

Lakshmi Puja is done in pradosha, the 3 muhurtas after sunset. Amavasya runs from 08:18 on Sat 22 Oct to 10:58 on Sun 23 Oct, so only Saturday’s pradosha (17:22–19:57) falls within it. Every reading takes that day.

Lakshmi Puja muhurat: pradosha, 17:22–19:57. Within it Vrishabha, a fixed (sthira) lagna, rises in the east from 18:32 to 19:57.

Diwali: every date in Chahārbāgh

The abhyanga bath is taken in arunodaya, the 96 minutes before sunrise. Chaturdashi runs from 05:36 on Fri 21 Oct to 08:18 on Sat 22 Oct, touching arunodaya on both mornings. The Nirnayasindhu takes the morning it holds more of: Sat 22 Oct. No text giving Narak Chaturdashi’s time was found; arunodaya is Tithika’s convention.

Narak Chaturdashi: every date in Chahārbāgh

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, 06:19 here. Trayodashi ended at 05:36 Fri, before it. Chaturdashi ends at 08:18, when the lead reaches 348°. The lead passed 180° at the full moon of 8 Oct, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Chaturdashi began at 05:36 Fri, before sunrise at 06:18 Fri, and ends at 08:18, after the next sunrise at 06:19. Both days read Chaturdashi: it is a vriddhi tithi here.

The night of Fri 21 Oct ran from sunset 17:23 Fri to sunrise 06:19, 12 h 56 m. Cut into 15 muhurtas of 51 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:19 to 17:22, splits into 8 choghadiyas of 1 h 22 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:22 to 06:20 Sun, 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 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 09:27, for Chitra.

Add the Sun's and the Moon's places among the stars: 184.7° + 171.8° = 356.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 12:55, 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 18:57 Fri, when the lead reached 342°; Shakuni runs until 08:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:19 to 06:20 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, 23 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 23 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: 30 Mar 2033, 21:21 Wed. Since then the Sun has moved 198.7° round the stars. Vikram Samvat numbers that year 2090; Shaka Samvat numbers it 1955.
