Molad
''Molad'' (מולד, plural ''Moladot'', מולדות) is a Hebrew word meaning "birth" that also generically refers to the time at which the New Moon is "born". The word is ambiguous, however, because depending on the context, it could refer to the actual or mean astronomical lunar conjunction (calculated by a specified method, for a specified time zone), or the ''molad'' of the traditional Hebrew calendar (or another specified calendar), or at a specified locale the first visibility of the new lunar crescent after a lunar conjunction. Other than its usage connected with the lunar cycle, ''מולד'' is also the word used in the Hebrew term for Christmas, ''חג המולד'' (literally "Holiday of the Birth" or "Holiday of the Nativity"). The traditional ''molad'' interval The ''average molad'' (), which is used for the traditional Hebrew calendar, is based on a constant interval cycle that is widely but incorrectly regarded as an approximation of the time in Jerusalem of the mea ...

Hebrew Calendar
The Hebrew calendar (), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance and as an official calendar of Israel. It determines the dates of Jewish holidays and other rituals, such as '' yahrzeits'' and the schedule of public Torah readings. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays alongside the Gregorian calendar. Like other lunisolar calendars, the Hebrew calendar consists of months of 29 or 30 days which begin and end at approximately the time of the new moon. As 12 such months comprise a total of just 354 days, an extra lunar month is added every 2 or 3 years so that the long-term average year length closely approximates the actual length of the solar year. Originally, the beginning of each month was determined based on physical observation of a new moon, while the decision of whether to add the leap month was based on observation ...

Rosh Hashanah
Rosh Hashanah (, , ) is the New Year in Judaism. The Hebrew Bible, biblical name for this holiday is Yom Teruah (, , ). It is the first of the High Holy Days (, , 'Days of Awe"), as specified by Leviticus 23:23–25, that occur in the late summer/early autumn of the Northern Hemisphere.

Helek
The helek, also spelled chelek (Hebrew חלק, meaning "portion", plural ''halakim'' חלקים) is a unit of time used in the calculation of the Molad. Other spellings used are ''chelak'' and ''chelek'', both with plural ''chalakim''. An hour is divided into 1080 halakim. A helek is 3 seconds or 1/18 minute. The ''helek'' derives from a small Babylonian time period called a ''she'', meaning '"barleycorn", itself equal to 1/72 of a Babylonian time degree (1° of celestial rotation). :360 degrees × 72 ''shes'' per degree / 24 hours = 1080 ''shes'' per hour.

Hebrew
Hebrew (; ''ʿÎbrit'') is a Northwest Semitic languages, Northwest Semitic language within the Afroasiatic languages, Afroasiatic language family. A regional dialect of the Canaanite languages, it was natively spoken by the Israelites and remained in regular use as a first language until after 200 CE and as the Sacred language, liturgical language of Judaism (since the Second Temple period) and Samaritanism. The language was Revival of the Hebrew language, revived as a spoken language in the 19th century, and is the only successful large-scale example of Language revitalization, linguistic revival. It is the only Canaanite language, as well as one of only two Northwest Semitic languages, with the other being Aramaic, still spoken today. The earliest examples of written Paleo-Hebrew alphabet, Paleo-Hebrew date back to the 10th century BCE. Nearly all of the Hebrew Bible is written in Biblical Hebrew, with much of its present form in the dialect that scholars believe flourish ...

Tishrei
Tishrei () or Tishri (; ''tīšrē'' or ''tīšrī''; from Akkadian ''tašrītu'' "beginning", from ''šurrû'' "to begin") is the first month of the civil year (which starts on 1 Tishrei) and the seventh month of the ecclesiastical year (which starts on 1 Nisan) in the Hebrew calendar. The name of the month is Babylonian. It is a month of 30 days. Tishrei usually occurs in September–October on the Gregorian calendar. In the Hebrew Bible the month is called Ethanim ( – ), or simply the seventh month. In the Babylonian calendar the month is known as Araḫ Tišritum, "Month of Beginning" (of the second half-year). Edwin R. Thiele has concluded, in '' The Mysterious Numbers of the Hebrew Kings'', that the ancient Kingdom of Judah counted years using the civil year starting in Tishrei, while the Kingdom of Israel counted years using the ecclesiastical new year starting in Nisan. Tishrei is the month used for the counting of the epoch year – i.e., the count of the year i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Month
A month is a unit of time, used with calendars, that is approximately as long as a natural phase cycle of the Moon; the words ''month'' and ''Moon'' are cognates. The traditional concept of months arose with the cycle of Moon phases; such lunar months ("lunations") are Lunar month#Synodic month, synodic months and last approximately 29.53 days, making for roughly 12.37 such months in one Earth year. From excavated tally sticks, researchers have deduced that people counted days in relation to the Moon's phases as early as the Paleolithic age. Synodic months, based on the Moon's orbital period with respect to the Earth–Sun line, are still the basis of many calendars today and are used to divide the year. Calendars that developed from the Roman calendar system, such as the internationally used Gregorian calendar, divide the year into 12 months, each of which lasts between 28 and 31 days. The names of the months were Anglicized from various Latin names and events important to Rome, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Universal Time
Universal Time (UT or UT1) is a time standard based on Earth's rotation. While originally it was mean solar time at 0° longitude, precise measurements of the Sun are difficult. Therefore, UT1 is computed from a measure of the Earth's angle with respect to the International Celestial Reference Frame (ICRF), called the Earth Rotation Angle (ERA, which serves as the replacement for Greenwich Mean Sidereal Time). UT1 is the same everywhere on Earth. UT1 is required to follow the relationship :ERA = 2π(0.7790572732640 + 1.00273781191135448'' · Tu'') radians where ''Tu'' = ( Julian UT1 date − 2451545.0). History Prior to the introduction of standard time, each municipality throughout the clock-using world set its official clock, if it had one, according to the local position of the Sun (see solar time). This served adequately until the introduction of rail travel in Britain, which made it possible to travel fast enough over sufficiently long distances as to req ...

Astronomical Conjunction
In astronomy, a conjunction occurs when two astronomical objects or spacecraft appear to be close to each other in the sky. This means they have either the same right ascension or the same ecliptic longitude, usually as observed from Earth. When two objects always appear close to the ecliptic—such as two planets, the Moon and a planet, or the Sun and a planet—this fact implies an apparent close approach between the objects as seen in the sky. A related word, '' appulse'', is the minimum apparent separation in the sky of two astronomical objects. Conjunctions involve either two objects in the Solar System or one object in the Solar System and a more distant object, such as a star. A conjunction is an apparent phenomenon caused by the observer's perspective: the two objects involved are not actually close to one another in space. Conjunctions between two bright objects close to the ecliptic, such as two bright planets, can be seen with the naked eye. The astronomical symbol f ...

Lunisolar
A lunisolar calendar is a calendar in many cultures, that combines monthly lunar cycles with the solar year. As with all calendars which divide the year into months, there is an additional requirement that the year have a whole number of months (Moon cycles). The majority of years have twelve months but every second or third year is an embolismic month, embolismic year, which adds a thirteenth Intercalation (timekeeping), intercalary, embolismic, or leap month. Lunisolar calendars are lunar calendars but, in contrast to purely lunar calendars such as the Islamic calendar, have additional intercalation rules that reset them periodically into a rough agreement with the solar year and thus with the seasons.

Shabbat
Shabbat (, , or ; , , ) or the Sabbath (), also called Shabbos (, ) by Ashkenazi Hebrew, Ashkenazim, is Judaism's day of rest on the seventh day of the seven-day week, week—i.e., Friday prayer, Friday–Saturday. On this day, religious Jews remember the biblical stories describing the Genesis creation narrative, creation of the heaven and earth in six days and the redemption from slavery and the Exodus from Egypt. Since the Hebrew calendar, Jewish religious calendar counts days from sunset to sunset, Shabbat begins in the evening of what on the civil calendar is Friday. Shabbat observance entails refraining from 39 Melachot, work activities, often with shomer Shabbat, great rigor, and engaging in restful activities to honor the day. Judaism's traditional position is that the unbroken seventh-day Shabbat originated among the Jewish people, as their first and most sacred institution. Variations upon Shabbat are widespread in Judaism and, with adaptations, throughout the Abraham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synagogue
A synagogue, also called a shul or a temple, is a place of worship for Jews and Samaritans. It is a place for prayer (the main sanctuary and sometimes smaller chapels) where Jews attend religious services or special ceremonies such as weddings, bar and bat mitzvahs, choir performances, and children's plays. They often also have rooms for study, social halls, administrative and charitable offices, classrooms for religious and Hebrew studies, and many places to sit and congregate. They often display commemorative, historic, or modern artwork alongside items of Jewish historical significance or history about the synagogue itself. Synagogues are buildings used for Jewish prayer, study, assembly, and reading of the Torah. The Torah (Pentateuch or Five Books of Moses) is traditionally read in its entirety over a period of a year in weekly portions during services, or in some synagogues on a triennial cycle. However, the edifice of a synagogue as such is not essential for hol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
