Birkat Hachama
''Birkat Hachama'' (, "Blessing of the Sun") refers to a rare Jewish blessing that is recited to the Creator, thanking God for creating the sun. The blessing is recited when the Sun completes its cycle every 28 years on a Tuesday at sundown. Jewish tradition says that when the Sun completes this cycle, it has returned to its position when the world was created. Because the blessing needs to be said when the Sun is visible, the blessing is postponed to the following day, on Wednesday morning. According to Judaism, the Sun has a 28-year solar cycle known as ''machzor gadol'' (, "the great cycle"). A solar year is estimated as 365.25 days and the "Blessing of the Sun", being said at the beginning of this cycle, is thus recited every 10,227 (28 times 365.25) days. The last time that it was recited was on April 8, 2009 (14 ''Nisan'' 5769 on the Hebrew calendar.) From an astronomical point of view, there is nothing special to these dates; e.g. the Sun, Moon, planets and stars will not ...

Sunrise
Sunrise (or sunup) is the moment when the upper rim of the Sun appears on the horizon in the morning, at the start of the Sun path. The term can also refer to the entire process of the solar disk crossing the horizon. Terminology Although the Sun appears to "rise" from the horizon, it is actually the ''Earth's'' motion that causes the Sun to appear. The illusion of a moving Sun results from Earth observers being in a rotating reference frame; this apparent motion caused many cultures to have mythologies and religions built around the geocentric model, which prevailed until astronomer Nicolaus Copernicus formulated his heliocentric model in the 16th century. Architect Buckminster Fuller proposed the terms "sunsight" and "sunclipse" to better represent the heliocentric model, though the terms have not entered into common language. Astronomically, sunrise occurs for only an instant, namely the moment at which the upper limb of the Sun appears tangent to the horizon. However, th ...

March Equinox
The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox (or spring equinox) in the Northern Hemisphere and as the autumnal equinox (or fall equinox) in the Southern Hemisphere. On the Gregorian calendar at 0° longitude, the northward equinox can occur as early as 19 March (which happened most recently in 1796, and will happen next in 2044), and it can occur as late as 21 March (which happened most recently in 2007, and will happen next in 2102). For a common year the computed time slippage is about 5 hours 49 minutes ''later'' than the previous year, and for a leap year about 18 hours 11 minutes ''earlier'' than the previous year. Balancing the increases of the common years against the losses of the leap years keeps the calendar date of the March equinox from drifting more than ...

Orach Chaim
''Orach Chayim'' ("manner/way of life") is a section of Rabbi Jacob ben Asher's compilation of Halakha (Jewish law), ''Arba'ah Turim''. This section addresses aspects of Jewish law pertinent to the Hebrew calendar (be it the daily, weekly, monthly, or annual calendar). Rabbi Yosef Karo modeled the framework of the '' Shulkhan Arukh'' (שולחן ערוך), his own compilation of practical Jewish law, after the ''Arba'ah Turim.'' Many later commentators used this framework, as well. Thus, ''Orach Chayim'' in common usage may refer to another area of halakha, separate from Rabbi Jacob ben Asher's compilation. ''Orach Chayim'' deals with but is not limited to: *Washing the hands in the morning *Tefillin *Tzitzit (ritual fringes) *Prayer *Sabbath *Festivals *Torah reading in synagogue. Commentaries on the ''Shulchan Aruch'' – ''Orach Chayim'' * ''Taz (Turei Zohov)'' – by Rabbi David HaLevi Segal * ''Magen Avraham'' – by Rabbi [ vraham Gombiner * ''Biur HaGra'' – by the V ...

Chofetz Chaim
The ''Sefer'' ''Chofetz Chaim'' (or ''Chafetz Chaim'' or ''Hafetz Hayim'') (, trans. "Pursuer of Life") is a book by Rabbi Yisrael Meir Kagan, who is also called "the Chofetz Chaim" after it. The book deals with the Jewish laws of speech. The title of the ''Chafetz Chaim'' is taken from Psalms: The book's subject is ''Hilchoth Shmirath HaLashon'' (laws of clean speech). Kagan provides copious sources from the Torah, Talmud, and ''Rishonim'' about the severity of Jewish law on tale-mongering and gossip. Lashon hara, literally "'the evil tongue", i.e., evil speech (or loosely gossip and slander and prohibitions of defamation), is sometimes translated as "prohibitions of slander", but most commonly concerns the prohibitions of saying evil/bad/unpleasant things, whether or not they are true. The book is divided into three parts: * The legal text is ''Mekor Chayim'' ("Source of Life"). * ''Be'er Mayim Chayim'' ("Well of living water"), the footnotes and legal argument. * It is co ...

Shulchan Aruch
The ''Shulhan Arukh'' ( ),, often called "the Code of Jewish Law", is the most widely consulted of the various legal codes in Rabbinic Judaism. It was authored in the city of Safed in what is now Israel by Joseph Karo in 1563 and published in Venice two years later. Together with its commentaries, it is the most widely accepted compilation of halakha or Jewish law ever written. The halachic rulings in the ''Shulhan Arukh'' generally follow Sephardic law and customs, whereas Ashkenazi Jews generally follow the halachic rulings of Moses Isserles, whose glosses to the ''Shulhan Aruch'' note where the Sephardic and Ashkenazi customs differ. These glosses are widely referred to as the ''mappā'' "tablecloth" to the "Set Table". Almost all published editions of the ''Shulchan Aruch'' include this gloss, and the term has come to denote both Karo's work as well as Isserles', with Karo usually referred to as "the ''Meḥabbēr''" (, "Author") and Isserles as "the Rema" (a Hebrew acr ...

Abraham Ibn Ezra
Abraham ben Meir Ibn Ezra (, often abbreviated as ; ''Ibrāhim al-Mājid ibn Ezra''; also known as Abenezra or simply ibn Ezra, 1089 / 1092 – 27 January 1164 / 23 January 1167)''Jewish Encyclopedia''online; '' Chambers Biographical Dictionary'' gives the dates 1092/93 – 1167 was one of the most distinguished Jewish biblical commentators and philosophers of the Middle Ages. He was born in Tudela, Taifa of Zaragoza (now Navarre). Biography Abraham Ibn Ezra was born in Tudela, one of the oldest and most important Jewish communities in Navarre. At the time, the town was under the rule of the emirs of the Muslim Taifa of Zaragoza. However, when he later moved to Córdoba, he claimed it was his birthplace.

Asher Ben Jehiel
Asher ben Jehiel (, or Asher ben Yechiel, sometimes Asheri) (1250 or 1259 – 1327) was an eminent rabbi and Talmudist best known for his abstract of Talmudic law. He is often referred to as Rabbenu Asher, “our Rabbi Asher” or by the Hebrew acronym for this title, the Rosh (). His yahrzeit is on 9 Cheshvan. Biography The Rosh was probably born in Cologne, Holy Roman Empire, and died in Toledo. His family was prominent for learning and piety, his father Yechiel was a Talmudist, and one of his ancestors was Rabbi Eliezer ben Nathan (the ''RaABaN''). Asher had eight sons, the most prominent of whom were Jacob (author of the ''Arba'ah Turim'') and Judah. In 1286, King Rudolf I had instituted a new persecution of the Jews, and the great teacher of the Rosh, Rabbi Meir of Rothenburg, left Germany but was captured and imprisoned. The Rosh raised a ransom for his release, but Rabbi Meir refused it, for fear of encouraging the imprisonment of other rabbis. Thereafter the Rosh a ...

Winter Solstice
The winter solstice, or hibernal solstice, occurs when either of Earth's geographical pole, poles reaches its maximum axial tilt, tilt away from the Sun. This happens twice yearly, once in each hemisphere (Northern Hemisphere, Northern and Southern Hemisphere, Southern). For that hemisphere, the winter solstice is the day with the shortest daytime, period of daylight and longest night of the year, and when the Sun is at its lowest culmination, daily maximum elevation in the sky. Each Polar Circle, polar region experiences polar night, continuous darkness or twilight around its winter solstice. The opposite event is the summer solstice. The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (December 21 or 22) and in the Southern Hemisphere, this is the June solstice (June 20 or 21). Although the winter solstice itself lasts only a moment, the term also refers to the day on which it occurs. Traditionally, in many Tem ...

Summer Solstice
The summer solstice or estival solstice occurs when one of Earth's poles has its maximum tilt toward the Sun. It happens twice yearly, once in each hemisphere ( Northern and Southern). The summer solstice is the day with the longest period of daylight and shortest night of the year in that hemisphere, when the sun is at its highest position in the sky. At either pole there is continuous daylight at the time of its summer solstice. The opposite event is the winter solstice. The summer solstice occurs during the hemisphere's summer. In the Northern Hemisphere, this is the June solstice (20, 21 or 22 June) and in the Southern Hemisphere, this is the December solstice (20, 21, 22 or 23 of December). Since prehistory, the summer solstice has been a significant time of year in many cultures, and has been marked by festivals and rituals. Traditionally, in temperate regions (especially Europe), the summer solstice is seen as the middle of summer and referred to as midsum ...
