Panchang in Sevan, Gegharkunik, Armenia Sat 25 Aug 1900

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 348°–360° is the 30th, Krishna Amavasya. A day takes the tithi in force at its sunrise, 05:19 here. Chaturdashi ended at 05:03 Fri, before it. Amavasya ends at 06:52, when the lead reaches 360°. The lead passed 180° at the full moon of 11 Aug, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 05:03 Fri, before sunrise at 05:18 Fri, and ends at 06:52, after the next sunrise at 05:19. Both days read Amavasya: it is a vriddhi tithi here.

The night of Fri 24 Aug ran from sunset 18:45 Fri to sunrise 05:19, 10 h 34 m. Cut into 15 muhurtas of 42 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:19 to 18:43, 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, 18:43 to 05:20 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′. Magha spans 120°00′–133°20′; the Moon entered its pada 3 at 126°40′. It leaves at 15:31, for Purva Phalguni.

Add the Sun's and the Moon's places among the stars: 128.9° + 128.2° = 257.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 253°20′–266°40′ is the 20th, Shiva. It ends at 22:54, then Siddha.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Amavasya is Chatushpada and the second Nagava. Chatushpada ended at 17:55 Fri, when the lead reached 354°; Nagava runs until 06:52.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:19 to 05:20 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: Karka gives Shravana. The Sun enters Simha on 15 Aug, inside the month. The next new moon, 25 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 25 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: 30 Mar 1900, 23:30 Fri. Since then the Sun has moved 141.7° round the stars. Vikram Samvat numbers that year 1957; Shaka Samvat numbers it 1822.
