Note 14 — ADAMS AND JEFFERSON
Reading edition
The old method, established by Julius Cæsar, of counting 365 days in a year, and 366 every fourth year, gave each year about eleven minutes too much, which overplus amounted in 1582 to ten days. In that year Pope Gregory XIII discontinued the “Julian” and established the “Gregorian” calendar, by setting forward the date of a day ten days. This change was adopted (the dropping of an additional day being needed) by the English Parliament in 1751,—September 3, 1752, to be called September 14. At present, the New Style gives 366 days to every year divisible by four, excepting 1800, 1900, etc.
