Panchang in Chahārbāgh, Alborz Province, Iran Sat 24 Apr 2027

The Sankashti fast is broken at moonrise. Chaturthi runs from 02:21 on Sat 24 Apr to 03:42 on Sun 25 Apr, so it holds moonrise only on Sat 24 Apr, at 22:39. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Chahārbāgh

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 216°–228° is the 19th, Krishna Chaturthi. A day takes the tithi in force at its sunrise, 05:23 here. Tritiya ended at 02:21, before it. Chaturthi ends at 03:42 Sun, when the lead reaches 228°. The lead passed 180° at the full moon of 21 Apr, so the Moon is waning: Krishna paksha.

The night of Fri 23 Apr ran from sunset 18:46 Fri to sunrise 05:23, 10 h 37 m. Cut into 15 muhurtas of 42 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:23 to 18:47, splits into 8 choghadiyas of 1 h 40 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:47 to 05:22 Sun, splits into 8 choghadiyas of 1 h 19 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′. Jyeshtha spans 226°40′–240°00′; the Moon entered its pada 1 at 226°40′. It leaves at 06:57 Sun, for Mula.

Add the Sun's and the Moon's places among the stars: 9.4° + 226.9° = 236.3°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 11:58, then Parigha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturthi is Bava and the second Balava. Bava runs until 14:57, when the lead reaches 222°; Balava until 03:42 Sun.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:23 to 05:22 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 6 May, finds it in Mesha and begins Vaishakha.

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 6 May, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra 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 16.7° round the stars. Vikram Samvat numbers that year 2084; Shaka Samvat numbers it 1949.
