Christian. Era
The western world (as well as most of the rest of the world) uses the Gregorian calendar. The calendar is of Christian and Roman pagan origins. The months and days of the week are named after Roman pagan gods and goddesses, and the calendar's epoch date (starting point) is 1 AD, the year Jesus Christ is estimated to have been born. The calendar has 365 days.
Properly speaking, there is no "English" calendar system. You probably mean the predominant Western Calendar (also called the Christian Calendar). This calendar system is best called the "Gregorian Calendar", after Pope Gregory XIII who introduced the calendar system in 1582.
It refers to the Christian era, beginning with year 1 AD or Anno Domini ("in the year of the Lord"), meaning the supposed first year of Christ's life - this was probably calculated incorrectly, but that makes no difference to the current calendar. Since Christians believe that Christ did not die but was reborn we are now in the year of the Lord 2011, meaning 2,011 years since His birth.Many other religions calculate dates in different ways, but many non-Christians and atheists happily use the Christian calendar.
