Panchang in Sofia, Sofia-Capital, Bulgaria Thu 12 Jul 2018

Amavasya follows the tithi at sunrise. Amavasya begins at 09:31 on Thu 12 Jul, after that sunrise, and ends at 05:47 on Fri 13 Jul, before the next: it holds no sunrise. A tithi that holds no sunrise is kept on the day it is current: Thu 12 Jul. No text giving Amavasya’s time was found; sunrise is Tithika’s convention.

Amavasya: every date in Sofia

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 336°–348° is the 29th, Krishna Chaturdashi. A day takes the tithi in force at its sunrise, 05:59 here. Trayodashi ended at 13:04 Wed, before it. Chaturdashi ends at 09:31, when the lead reaches 348°. The lead passed 180° at the full moon of 28 Jun, so the Moon is waning: Krishna paksha.

A day takes the tithi in force at its sunrise. Amavasya began at 09:31 and ended at 05:47 Fri, between the sunrises of 05:59 and 06:00 Fri. Thursday reads Chaturdashi and Friday reads Pratipada: Amavasya is a kshaya tithi here.

The night of Wed 11 Jul ran from sunset 21:05 Wed to sunrise 05:59, 8 h 54 m. Cut into 15 muhurtas of 35 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:59 to 21:04, splits into 8 choghadiyas of 1 h 53 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 21:04 to 06:00 Fri, splits into 8 choghadiyas of 1 h 7 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′. Ardra spans 66°40′–80°00′; the Moon entered its pada 2 at 70°. It leaves at 19:24, for Punarvasu.

Add the Sun's and the Moon's places among the stars: 85.6° + 71.5° = 157.1°. The sum, cut into 27 parts of 13°20′, gives the yoga: 146°40′–160°00′ is the 12th, Dhruva. It ends at 10:13, then Vyaghata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Chaturdashi is Vishti and the second Shakuni. Vishti ended at 23:20 Wed, when the lead reached 342°; Shakuni runs until 09:31.

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.

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: Vrishabha gives Jyeshtha. The Sun enters Mithuna on 15 Jun, inside the month. The next new moon, 13 Jul, finds it in Mithuna and begins Ashadha.

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 Jul, with the Sun in Mithuna, begins Ashadha. Until then this Krishna paksha reads Ashadha here, and Jyeshtha 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 112.8° round the stars. Vikram Samvat numbers that year 2075; Shaka Samvat numbers it 1940.
