Panchang in Sevan, Gegharkunik, Armenia Sun 15 Aug 1909

Amavasya follows the tithi at sunrise. Amavasya runs from 01:35 on Sun 15 Aug to 02:52 on Mon 16 Aug, so it holds sunrise only on Sun 15 Aug, at 05:07. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Sevan

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, 05:09 here. Chaturdashi ended at 01:37, before it. Amavasya ends at 02:54 Mon, when the lead reaches 360°. The lead passed 180° at the full moon of 2 Aug, so the Moon is waning: Krishna paksha.

The night of Sat 14 Aug ran from sunset 19:00 Sat to sunrise 05:09, 10 h 9 m. Cut into 15 muhurtas of 40 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:09 to 18:58, splits into 8 choghadiyas of 1 h 43 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:58 to 05:10 Mon, splits into 8 choghadiyas of 1 h 16 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′. Ashlesha spans 106°40′–120°00′; the Moon entered its pada 1 at 106°40′. It leaves at 03:09 Mon, for Magha.

Add the Sun's and the Moon's places among the stars: 119° + 108.7° = 227.7°. The sum, cut into 27 parts of 13°20′, gives the yoga: 226°40′–240°00′ is the 18th, Variyana. It ends at 03:22 Mon, then Parigha.

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 runs until 14:13, when the lead reaches 354°; Nagava until 02:54 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:09 to 05:10 Mon, so the hours after midnight still belong to Raviwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 17 Jul 13:44 Sat to 16 Aug 02:54 Mon the Sun stayed in Karka, entering Simha at 16 Aug 06:05 Mon, after the new moon. A month with no sankranti is Adhika Shravana, before Shravana itself.

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 16 Aug, with the Sun in Karka, begins Shravana (Adhik). Until then this Krishna paksha reads Shravana (Adhik) here, and Shravana (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 21 Mar 1909, 23:11 Sun. Since then the Sun has moved 141° round the stars. Vikram Samvat numbers that year 1966; Shaka Samvat numbers it 1831.
