Panchang in Sevan, Gegharkunik, Armenia Mon 14 Mar 1983

Amavasya follows the tithi at sunrise. Amavasya runs from 20:28 on Sun 13 Mar to 21:43 on Mon 14 Mar, so it holds sunrise only on Mon 14 Mar, at 07:14. 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, 07:14 here. Chaturdashi ended at 20:28 Sun, before it. Amavasya ends at 21:43, when the lead reaches 360°. The lead passed 180° at the full moon of 27 Feb, so the Moon is waning: Krishna paksha.

The night of Sun 13 Mar ran from sunset 19:03 Sun to sunrise 07:14, 12 h 11 m. Cut into 15 muhurtas of 48 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 07:14 to 19:04, splits into 8 choghadiyas of 1 h 28 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:04 to 07:13 Tue, splits into 8 choghadiyas of 1 h 31 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 1 at 320°. It leaves at 04:11 Tue, for Uttara Bhadrapada.

Add the Sun's and the Moon's places among the stars: 329.4° + 322.4° = 651.8°, one full turn and 291.8°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 280°00′–293°20′ is the 22nd, Sadhya. It ends at 09:59, then Shubha.

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 09:09, when the lead reaches 354°; Nagava until 21:43.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 07:14 to 07:13 Tue, so the hours after midnight still belong to Somawara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 13 Feb 04:31 Sun to 14 Mar 21:43 the Sun stayed in Kumbha, entering Meena at 14 Mar 22:44, after the new moon. A month with no sankranti is Adhika Phalguna, before Phalguna 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 14 Mar, with the Sun in Kumbha, begins Phalguna (Adhik). Until then this Krishna paksha reads Phalguna (Adhik) here, and Phalguna (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 25 Mar 1982, 14:17 Thu. Since then the Sun has moved 348.6° round the stars. Vikram Samvat numbers that year 2039; Shaka Samvat numbers it 1904.
