Panchang in Pāthardi, Maharashtra Thu 16 Jul 2015

Amavasya follows the tithi at sunrise. Amavasya runs from 06:38 on Wed 15 Jul to 06:54 on Thu 16 Jul, so it holds sunrise only on Thu 16 Jul, at 05:59. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Pāthardi

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, 05:59 here. Chaturdashi ended at 06:38 Wed, before it. Amavasya ends at 06:54, when the lead reaches 360°. The lead passed 180° at the full moon of 2 Jul, so the Moon is waning: Krishna paksha.

The night of Wed 15 Jul ran from sunset 19:10 Wed to sunrise 05:59, 10 h 49 m. Cut into 15 muhurtas of 43 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:59 to 19:10, splits into 8 choghadiyas of 1 h 38 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 19:10 to 06:00 Fri, splits into 8 choghadiyas of 1 h 21 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 14:48, for Pushya.

Add the Sun's and the Moon's places among the stars: 89.1° + 88.7° = 177.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 173°20′–186°40′ is the 14th, Harshana. It ends at 21:38, 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 18:42 Wed, when the lead reached 354°; Nagava runs until 06:54.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:59 to 06:00 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 16 Jun 19:35 Tue to 16 Jul 06:54 the Sun stayed in Mithuna, entering Karka at 17 Jul 04:02 Fri, 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 16 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: 20 Mar 2015, 15:06 Fri. Since then the Sun has moved 113.7° round the stars. Vikram Samvat numbers that year 2072; Shaka Samvat numbers it 1937.
