Panchang in Chahārbāgh, Alborz Province, Iran Thu 20 Nov 2025

Amavasya follows the tithi at sunrise. Amavasya runs from 07:44 on Wed 19 Nov to 10:17 on Thu 20 Nov, so it holds sunrise only on Thu 20 Nov, at 06:47. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Chahārbāgh

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, 06:47 here. Chaturdashi ended at 07:44 Wed, before it. Amavasya ends at 10:17, when the lead reaches 360°. The lead passed 180° at the full moon of 5 Nov, so the Moon is waning: Krishna paksha.

The night of Wed 19 Nov ran from sunset 16:57 Wed to sunrise 06:47, 13 h 50 m. Cut into 15 muhurtas of 55 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:47 to 16:56, splits into 8 choghadiyas of 1 h 16 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 16:56 to 06:48 Fri, splits into 8 choghadiyas of 1 h 44 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′. Vishakha spans 200°00′–213°20′; the Moon entered its pada 4 at 210°. It leaves at 08:58, for Anuradha.

Add the Sun's and the Moon's places among the stars: 213.8° + 212.3° = 426.1°, one full turn and 66.1°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 53°20′–66°40′ is the 5th, Shobhana. It ends at 07:52, then Atiganda.

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 ended at 21:00 Wed, when the lead reached 354°; Nagava runs until 10:17.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:47 to 06:48 Fri, so the hours after midnight still belong to Guruwara.

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: Tula gives Kartika. The Sun enters Vrishchika on 16 Nov, inside the month. The next new moon, 20 Nov, finds it in Vrishchika and begins Margashirsha.

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 20 Nov, with the Sun in Vrishchika, begins Margashirsha. Until then this Krishna paksha reads Margashirsha here, and Kartika in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 29 Mar 2025, 14:27 Sat. Since then the Sun has moved 229° round the stars. Vikram Samvat numbers that year 2082; Shaka Samvat numbers it 1947.
