Panchang in Sevan, Gegharkunik, Armenia Wed 26 Jun 2013

The Sankashti fast is broken at moonrise. Chaturthi runs from 04:27 on Wed 26 Jun to 01:30 on Thu 27 Jun, so it holds moonrise only on Wed 26 Jun, at 22:43. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Sevan

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, 05:31 here. Tritiya ended at 04:27, before it. Chaturthi ends at 01:30 Thu, when the lead reaches 228°. The lead passed 180° at the full moon of 23 Jun, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 05:25, came before Tritiya ended at 05:57: this day reads Tritiya. Chaturthi ends at 03:00 Thu, before the next sunrise, so no day here reads Chaturthi: it is kshaya.

Sunrise here, 05:31, came after Tritiya ended at 04:27: this day reads Chaturthi.

The night of Tue 25 Jun ran from sunset 20:34 Tue to sunrise 05:31, 8 h 57 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:31 to 20:34, splits into 8 choghadiyas of 1 h 52 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:34 to 05:31 Thu, splits into 8 choghadiyas of 1 h 7 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′. Shravana spans 280°00′–293°20′; the Moon entered its pada 3 at 286°40′. It leaves at 15:32, for Dhanishtha.

Add the Sun's and the Moon's places among the stars: 70.6° + 287.2° = 357.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 08:55, then Vishkambha.

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 14:54, when the lead reaches 222°; Balava until 01:30 Thu.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:31 to 05:31 Thu, so the hours after midnight still belong to Budhawara.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 8 Jul, finds it in Mithuna and begins Ashadha.

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 8 Jul, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 10 Apr 2013, 13:35 Wed. Since then the Sun has moved 74° round the stars. Vikram Samvat numbers that year 2070; Shaka Samvat numbers it 1935.
