Cyber Black Friday
The Catholic Church is fundamentally liturgical and sacramental in its public life of worship.
As explained in greater detail in the Catechism of the Catholic Church and its shorter Compendium, the liturgy is something that "the whole Christ", Head and Body, celebrates — Christ, the one High Priest, together with his Body, the Church in heaven and on earth. Involved in the heavenly liturgy are the angels and the saints of the Old Covenant and the New, in particular Mary, the Mother of God, the Apostles, the Martyrs and "a great multitude, which no man could number, out of every nation and of all tribes and peoples and tongues" (Revelation 7:9). The Church on earth, "a royal priesthood" (1 Peter 2:9), celebrates the liturgy in union with these: the baptized offering themselves as a spiritual sacrifice, the ordained ministers celebrating at the service of all the members of the Church in accordance with the order received, and bishops and priests acting in the person of Christ.
Cyber Black Friday is a marketing term for the online version of Black Friday, the Friday following Thanksgiving Day in the United States. The term made its debut in a 2009 press release entitled "Black Friday Goes Online for Cyber Black Friday". According to the National Retail Federation Black Friday shopping survey, 195 million shoppers visited stores and websites over Black Friday weekend in 2009, up from 172 million last year. One-fourth of Americans shopping over the Black Friday weekend (28.5% or 49 million) were shopping online. comScore reported that Black Friday (November 27, 2009) saw $595 million in online sales, representing an 11% increase versus Black Friday 2008. Gian Fulgoni of comScore said, "Black Friday, better known as a shopping bonanza in brick-and-mortar retail stores, is increasingly becoming one of the landmark days in the online holiday shopping world." Some Cyber Black Friday sales are short-lived, last through the weekend, into Cyber Monday, and beyond.
A leap year (or intercalary or bissextile year) is a year containing one additional day (or, in the case of lunisolar calendars, a month) in order to keep the calendar year synchronized with the astronomical or seasonal year. Because seasons and astronomical events do not repeat in a whole number of days, a calendar that had the same number of days in each year would, over time, drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year.
For example, in the Gregorian calendar (a common solar calendar), February in a leap year has 29 days instead of the usual 28, so the year lasts 366 days instead of the usual 365. Similarly, in the Hebrew calendar (a lunisolar calendar), Adar Aleph, a 13th lunar month is added seven times every 19 years to the twelve lunar months in its common years to keep its calendar year from drifting through the seasons.
