Panchang in Khmelnytskyi, Ukraine Sun 15 Apr 2018

Amavasya follows the tithi at sunrise. Amavasya runs from 06:07 on Sun 15 Apr to 04:57 on Mon 16 Apr, so it holds sunrise only on Sun 15 Apr, at 06:20. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Khmelnytskyi

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, 06:20 here. Chaturdashi ended at 06:07, before it. Amavasya ends at 04:57 Mon, when the lead reaches 360°. The lead passed 180° at the full moon of 31 Mar, so the Moon is waning: Krishna paksha.

The night of Sat 14 Apr ran from sunset 20:02 Sat to sunrise 06:20, 10 h 18 m. Cut into 15 muhurtas of 41 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:20 to 20:04, splits into 8 choghadiyas of 1 h 43 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 20:04 to 06:18 Mon, splits into 8 choghadiyas of 1 h 16 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′. Revati spans 346°40′–360°00′; the Moon entered its pada 1 at 346°40′. It leaves at 01:34 Mon, for Ashwini.

Add the Sun's and the Moon's places among the stars: 1° + 349.1° = 350.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 346°40′–360°00′ is the 27th, Vaidhriti. It ends at 22:39, then Vishkambha.

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 17:36, when the lead reaches 354°; Nagava until 04:57 Mon.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:20 to 06:18 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: Meena gives Chaitra. The Sun enters Mesha on 14 Apr, inside the month. The next new moon, 16 Apr, finds it in Mesha and begins Vaishakha.

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 Apr, with the Sun in Mesha, begins Vaishakha. Until then this Krishna paksha reads Vaishakha here, and Chaitra in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 17 Mar 2018, 15:11 Sat. Since then the Sun has moved 28.2° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
