Panchang in Pāthardi, Maharashtra Sun 13 Aug 1950

Amavasya follows the tithi at sunrise. Amavasya runs from 22:47 on Sat 12 Aug to 22:18 on Sun 13 Aug, so it holds sunrise only on Sun 13 Aug, at 06:09. 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, 06:09 here. Chaturdashi ended at 22:47 Sat, before it. Amavasya ends at 22:18, when the lead reaches 360°. The lead passed 180° at the full moon of 29 Jul, so the Moon is waning: Krishna paksha.

The night of Sat 12 Aug ran from sunset 18:59 Sat to sunrise 06:09, 11 h 10 m. Cut into 15 muhurtas of 44 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:09 to 18:58, splits into 8 choghadiyas of 1 h 36 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 06:09 Mon, splits into 8 choghadiyas of 1 h 23 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 03:21 Mon, for Magha.

Add the Sun's and the Moon's places among the stars: 116.5° + 108.3° = 224.8°. The sum, cut into 27 parts of 13°20′, gives the yoga: 213°20′–226°40′ is the 17th, Vyatipata. It ends at 09:18, then Variyana.

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 10:36, when the lead reaches 354°; Nagava until 22:18.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:09 to 06:09 Mon, so the hours after midnight still belong to Raviwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 13 Aug, finds it in Karka and begins Shravana.

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 13 Aug, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 18 Mar 1950, 20:50 Sat. Since then the Sun has moved 142.2° round the stars. Vikram Samvat numbers that year 2007; Shaka Samvat numbers it 1872.
