Panchang in Chahārbāgh, Alborz Province, Iran Sat 10 Apr 2032

Ghatasthapana is done in pratahkala, the first fifth of the day. Pratipada runs from 06:09 on Sat 10 Apr to 04:11 on Sun 11 Apr, so it touches only Saturday’s pratahkala (05:40–08:15). No text giving Chaitra Navratri · Ghatasthapana’s time was found; pratahkala is Tithika’s convention.

Chaitra Navratri: every date in Chahārbāgh

Vikram Samvat 2089 begins with Chaitra Shukla Pratipada. Here Pratipada holds no sunrise, so the year begins on the day it is current: Sat 10 Apr.

Amavasya follows the tithi at sunrise. Amavasya runs from 08:33 on Fri 9 Apr to 06:09 on Sat 10 Apr, so it holds sunrise only on Sat 10 Apr, at 05:40. 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, 05:40 here. Chaturdashi ended at 08:33 Fri, before it. Amavasya ends at 06:09, when the lead reaches 360°. The lead passed 180° at the full moon of 27 Mar, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Pratipada began at 06:09 and ended at 04:11 Sun, between the sunrises of 05:40 and 05:38 Sun. Saturday reads Amavasya and Sunday reads Dwitiya: Pratipada is a kshaya tithi here.

The night of Fri 9 Apr ran from sunset 18:35 Fri to sunrise 05:40, 11 h 5 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:40 to 18:36, 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 night here, 18:36 to 05:38 Sun, 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 fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Revati spans 346°40′–360°00′; the Moon entered its pada 3 at 353°20′. It leaves at 12:07, for Ashwini.

Add the Sun's and the Moon's places among the stars: 356.5° + 356.2° = 712.7°, one full turn and 352.7°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 17:19, then Vishkambha.

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 19:18 Fri, when the lead reached 354°; Nagava runs until 06:09.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:40 to 05:38 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: Kumbha gives Phalguna. The Sun enters Meena on 14 Mar, inside the month. The next new moon, 10 Apr, finds it in Meena and begins Chaitra.

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 10 Apr, with the Sun in Meena, begins Chaitra. Until then this Krishna paksha reads Chaitra here, and Phalguna in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2032, 06:09. Since then the Sun has moved 0° round the stars. Vikram Samvat numbers that year 2089; Shaka Samvat numbers it 1954.
