Panchang in Sevan, Gegharkunik, Armenia Sat 19 Jan 1957

The Sankashti fast is broken at moonrise. Chaturthi runs from 22:09 on Fri 18 Jan to 18:57 on Sat 19 Jan, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Sat 19 Jan. 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, 07:19 here. Tritiya ended at 22:09 Fri, before it. Chaturthi ends at 18:57, when the lead reaches 228°. The lead passed 180° at the full moon of 16 Jan, so the Moon is waning: Krishna paksha.

The night of Fri 18 Jan ran from sunset 17:00 Fri to sunrise 07:19, 14 h 19 m. Cut into 15 muhurtas of 57 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:19 to 17:02, splits into 8 choghadiyas of 1 h 12 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:02 to 07:19 Sun, splits into 8 choghadiyas of 1 h 47 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′. Purva Phalguni spans 133°20′–146°40′; the Moon entered its pada 2 at 136°40′. It leaves at 23:12, for Uttara Phalguni.

Add the Sun's and the Moon's places among the stars: 275.6° + 136.9° = 412.5°, one full turn and 52.5°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 08:36, then Shobhana.

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 08:29, when the lead reaches 222°; Balava until 18:57.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:19 to 07:19 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: Dhanu gives Pausha. The Sun enters Makara on 13 Jan, inside the month. The next new moon, 31 Jan, finds it in Makara and begins Magha.

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 31 Jan, with the Sun in Makara, begins Magha. Until then this Krishna paksha reads Magha here, and Pausha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 1956, 05:38 Wed. Since then the Sun has moved 277.7° round the stars. Vikram Samvat numbers that year 2013; Shaka Samvat numbers it 1878.
