Panchang in Sevan, Gegharkunik, Armenia Mon 21 Aug 1978

The Sankashti fast is broken at moonrise. Chaturthi runs from 05:42 on Mon 21 Aug to 04:03 on Tue 22 Aug, so it holds moonrise only on Mon 21 Aug, at 21:38. 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, 06:15 here. Tritiya ended at 05:42, before it. Chaturthi ends at 04:03 Tue, when the lead reaches 228°. The lead passed 180° at the full moon of 18 Aug, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise.

Sunrise here, 05:53, came before Tritiya ended at 07:12: this day reads Tritiya. Chaturthi ends at 05:33 Tue, before the next sunrise, so no day here reads Chaturthi: it is kshaya.

Sunrise here, 06:15, came after Tritiya ended at 05:42: this day reads Chaturthi.

The night of Sun 20 Aug ran from sunset 19:51 Sun to sunrise 06:15, 10 h 24 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:15 to 19:49, splits into 8 choghadiyas of 1 h 41 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:49 to 06:16 Tue, splits into 8 choghadiyas of 1 h 18 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′. Uttara Bhadrapada spans 333°20′–346°40′; the Moon entered its pada 3 at 340°. It leaves at 17:00, for Revati.

Add the Sun's and the Moon's places among the stars: 124.1° + 340.4° = 464.5°, one full turn and 104.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 93°20′–106°40′ is the 8th, Dhriti. It ends at 09:39, then Shula.

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 16:47, when the lead reaches 222°; Balava until 04:03 Tue.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:15 to 06:16 Tue, so the hours after midnight still belong to Somawara.

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: Karka gives Shravana. The Sun enters Simha on 16 Aug, inside the month. The next new moon, 2 Sep, finds it in Simha and begins Bhadrapada.

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 2 Sep, with the Sun in Simha, begins Bhadrapada. Until then this Krishna paksha reads Bhadrapada here, and Shravana in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 7 Apr 1978, 19:15 Fri. Since then the Sun has moved 130.2° round the stars. Vikram Samvat numbers that year 2035; Shaka Samvat numbers it 1900.
