Pope Gregory XIII in 1582 issued a ruling stating the Julian calendar would be corrected in October 4 of the same year. The Julian calendar, the then-existing calendar, was erring by ten days. The new calendar, called the Gregorian calendar, did the following:
• Ten days were not included in October
• New standards were set to determine Easter
• New rules were established regarding Leap Day
Not everyone adopted the Gregorian calendar right away. Even those who adopted the calendar were not happy because they thought they had lost ten days of pay. Great Britain and colonial America did not change until September 1752. We still use the Gregorian calendar today.
