Panchang in Sevan, Gegharkunik, Armenia Thu 13 May 2010

Amavasya follows the tithi at sunrise. Amavasya runs from 06:38 on Thu 13 May to 06:04 on Fri 14 May, so it holds sunrise only on Thu 13 May, at 06:45. 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, 06:45 here. Chaturdashi ended at 06:38, before it. Amavasya ends at 06:04 Fri, when the lead reaches 360°. The lead passed 180° at the full moon of 28 Apr, so the Moon is waning: Krishna paksha.

The night of Wed 12 May ran from sunset 21:06 Wed to sunrise 06:45, 9 h 39 m. Cut into 15 muhurtas of 38 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:45 to 21:07, splits into 8 choghadiyas of 1 h 47 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:07 to 06:44 Fri, splits into 8 choghadiyas of 1 h 12 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′. Bharani spans 13°20′–26°40′; the Moon entered its pada 1 at 13°20′. It leaves at 01:37 Fri, for Krittika.

Add the Sun's and the Moon's places among the stars: 28.2° + 16.3° = 44.5°. The sum, cut into 27 parts of 13°20′, gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 21:44, then Shobhana.

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 18:24, when the lead reaches 354°; Nagava until 06:04 Fri.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:45 to 06:44 Fri, so the hours after midnight still belong to Guruwara.

A month normally holds one sankranti, the Sun's entry into a new rashi. From 14 Apr 17:28 Wed to 14 May 06:04 Fri the Sun stayed in Mesha, entering Vrishabha at 15 May 03:16 Sat, after the new moon. A month with no sankranti is Adhika Vaishakha, before Vaishakha 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 May, with the Sun in Mesha, begins Vaishakha (Adhik). Until then this Krishna paksha reads Vaishakha (Adhik) here, and Vaishakha (Adhik) in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 16 Mar 2010, 01:01 Tue. Since then the Sun has moved 57° round the stars. Vikram Samvat numbers that year 2067; Shaka Samvat numbers it 1932.
