Panchang in Sevan, Gegharkunik, Armenia Mon 6 Aug 1917

The Sankashti fast is broken at moonrise. Chaturthi runs from 21:01 on Sun 5 Aug to 17:46 on Mon 6 Aug, between the two nights’ moonrise, touching neither. The Dharmasindhu then takes the later day: Mon 6 Aug. 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, 05:00 here. Tritiya ended at 21:03 Sun, before it. Chaturthi ends at 17:48, when the lead reaches 228°. The lead passed 180° at the full moon of 3 Aug, so the Moon is waning: Krishna paksha.

The night of Sun 5 Aug ran from sunset 19:11 Sun to sunrise 05:00, 9 h 49 m. Cut into 15 muhurtas of 39 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:00 to 19:10, splits into 8 choghadiyas of 1 h 46 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:10 to 05:01 Tue, splits into 8 choghadiyas of 1 h 13 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 Bhadrapada spans 320°00′–333°20′; the Moon entered its pada 4 at 330°. It leaves at 08:52, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 110.3° + 330.9° = 441.2°, one full turn and 81.2°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 80°00′–93°20′ is the 7th, Sukarma. It ends at 23:28, then Dhriti.

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 07:23, when the lead reaches 222°; Balava until 17:48.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:00 to 05:01 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, 17 Aug, 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 17 Aug, 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: 23 Mar 1917, 07:04 Fri. Since then the Sun has moved 131° round the stars. Vikram Samvat numbers that year 1974; Shaka Samvat numbers it 1839.
