Panchang in Chahārbāgh, Alborz Province, Iran Thu 30 Sep 2027

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 06:06 on Thu 30 Sep to 03:35 on Fri 1 Oct, so it touches only Thursday’s pratahkala (06:00–08:23).

Sharad Navratri: every date in Chahārbāgh

Amavasya follows the tithi at sunrise. Amavasya runs from 08:55 on Wed 29 Sep to 06:06 on Thu 30 Sep, so it holds sunrise only on Thu 30 Sep, at 06:00. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

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, 06:00 here. Chaturdashi ended at 08:55 Wed, before it. Amavasya ends at 06:06, when the lead reaches 360°. The lead passed 180° at the full moon of 16 Sep, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:06 and ended at 03:35 Fri, between the sunrises of 06:00 and 06:01 Fri. Thursday reads Amavasya and Friday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Wed 29 Sep ran from sunset 17:54 Wed to sunrise 06:00, 12 h 6 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:00 to 17:52, splits into 8 choghadiyas of 1 h 29 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:52 to 06:01 Fri, splits into 8 choghadiyas of 1 h 31 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 1 at 160°. It leaves at 00:11 Fri, for Chitra.

Add the Sun's and the Moon's places among the stars: 162.5° + 162.4° = 324.9°. The sum, cut into 27 parts of 13°20′, gives the yoga: 320°00′–333°20′ is the 25th, Brahma. It ends at 19:09, then Indra.

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 19:29 Wed, when the lead reached 354°; Nagava runs until 06:06.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:00 to 06:01 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: Simha gives Bhadrapada. The Sun enters Kanya on 17 Sep, inside the month. The next new moon, 30 Sep, finds it in Kanya and begins Ashwina.

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 30 Sep, with the Sun in Kanya, begins Ashwina. Until then this Krishna paksha reads Ashwina here, and Bhadrapada in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 2027, 03:21 Wed. Since then the Sun has moved 169.8° round the stars. Vikram Samvat numbers that year 2084; Shaka Samvat numbers it 1949.
