THE CALENDAR: Gregorian calendar

The gregorian calendar is th one most used nowadays. It is named after Pope Gregory XIII who introduced it in 1582. There is a leap year every four years (or more precisely, 97 leap years every 400 years). This means that the year corresponds closely with the astronomical year (365.24219 days) so that it gets just one day out of sync in every 3,300 years.

*In a leap year, February has 29 days.

Problems in Gregorian calendar

Some non-Catholic countries such as Britain refused to adopt the Gregorian calendar at first . The Julian calendar previously used in Britain was based on a solar year, the time taken for the earth to rotate around the sun. This is 365.25 days, which is fractionally too long (it is actually 365.24219 days), so the calendar steadily fell out of line with the seasons. In 1752 Britain decided to correct this day by abandoning the Julian calendar in favour of the Gregorian. By doing so, 3 September instanly became 14 September – and, as a result, nothing whatsoever happened in British history between 3 and 13 September 1752. Many people believed their lives would be shortened. They protested in the streets, demanding, “Give us back our 11 days!”
