The Gregorian calendar was a reform of the Julian calendar instituted in 1582 by Pope Gregory XIII, after whom the calendar was named, by papal bull Inter gravissimas dated 24 February 1582. The motivation for the adjustment was to bring the date for the celebration of Easter to the time of year in which it was celebrated when it was introduced by the early Church. Although a recommendation of the First Council of Nicaea in 325 specified that all Christians should celebrate Easter on the same day, it took almost five centuries before virtually all Christians achieved that objective by adopting the rules of the Church of Alexandria (see Easter for the issues which arose).
What holiday led to the revision of the Gregorian calendar

In July 2010, Governor Chris Christie announced that a state takeover of the city and local government "was imminent". Comparing regulations in Atlantic City to an "antique car", Atlantic City regulatory reform is a key piece of Gov. Chris Christie's plan, unveiled on July 22, to reinvigorate an industry mired in a four-year slump in revenue and hammered by fresh competition from casinos in the surrounding states of Delaware, Pennsylvania, Connecticut, and more recently, Maryland. In January 2011, Chris Christie announced the Atlantic City Tourism District, a state-run district encompassing the boardwalk casinos, the marina casinos, the Atlantic City Outlets, and Bader Field. Fairleigh Dickinson University's PublicMind poll surveyed New Jersey voters' attitudes on the takeover. The February 16, 2011 survey showed that 43% opposed the measure while 29% favored direct state oversight. Interestingly, the poll also found that even South Jersey voters expressed opposition to the plan; 40% reported they opposed the measure and 37% reported they were in favor of it.

Historically, migration has been recorded as much as 3,000 years ago by Ancient Greek authors including Homer and Aristotle, and in the Book of Job, for species such as storks, turtle doves, and swallows. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and scientific studies have used techniques including bird ringing and satellite tracking. Threats to migratory birds have grown with habitat destruction especially of stopover and wintering sites, as well as structures such as power lines and wind farms.
When was migration first recorded?
A: 3,000 years ago

The impressive, costly, and centralised rites to the deities of the Roman state were vastly outnumbered in everyday life by commonplace religious observances pertaining to an individual's domestic and personal deities, the patron divinities of Rome's various neighborhoods and communities, and the often idiosyncratic blends of official, unofficial, local and personal cults that characterised lawful Roman religion. In this spirit, a provincial Roman citizen who made the long journey from Bordeaux to Italy to consult the Sibyl at Tibur did not neglect his devotion to his own goddess from home:
