Panchang in Sevan, Gegharkunik, Armenia Sat 15 Jul 1950

Amavasya follows the tithi at sunrise. Amavasya runs from 07:18 on Fri 14 Jul to 08:05 on Sat 15 Jul, so it holds sunrise only on Sat 15 Jul, at 04:41. 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, 04:41 here. Chaturdashi ended at 07:18 Fri, before it. Amavasya ends at 08:05, when the lead reaches 360°. The lead passed 180° at the full moon of 29 Jun, so the Moon is waning: Krishna paksha.

The night of Fri 14 Jul ran from sunset 19:30 Fri to sunrise 04:41, 9 h 11 m. Cut into 15 muhurtas of 36 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 04:41 to 19:29, splits into 8 choghadiyas of 1 h 51 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:29 to 04:42 Sun, splits into 8 choghadiyas of 1 h 9 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′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 3 at 86°40′. It leaves at 16:18, for Pushya.

Add the Sun's and the Moon's places among the stars: 88.8° + 87.2° = 176°. The sum, cut into 27 parts of 13°20′, gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 23:19, then Vajra.

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 19:45 Fri, when the lead reached 354°; Nagava runs until 08:05.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 04:41 to 04:42 Sun, so the hours after midnight still belong to Shaniwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 15 Jun 18:52 Thu to 15 Jul 08:05 the Sun stayed in Mithuna, entering Karka at 16 Jul 09:41 Sun, after the new moon. A month with no sankranti is Adhika Ashadha, before Ashadha 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 15 Jul, with the Sun in Mithuna, begins Ashadha (Adhik). Until then this Krishna paksha reads Ashadha (Adhik) here, and Ashadha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1950, 18:20 Sat. Since then the Sun has moved 114.5° round the stars. Vikram Samvat numbers that year 2007; Shaka Samvat numbers it 1872.
