CHAPTER I.

ERRORS OF THE JULIAN CALENDAR.


It will be necessary in the first place to understand the difference
between the Julian and Gregorian rule of intercalation. If the number of
any year be exactly divisible by four it is leap year; if the remainder be
1, it is the first year after leap-year; if 2, the second; if 3, the
third; thus:

  1888 / 4 = 472, no remainder.
  1889 / 4 = 472, remainder, 1.
  1890 / 4 = 472, remainder, 2.
  1891 / 4 = 472, remainder, 3.
  1892 / 4 = 473, no remainder.

And so on, every fourth year being leap-year of 366 days.

This is the Julian rule of intercalation, which is corrected by the
Gregorian by making every centurial year, or the year that completes the
century, a common year, if not exactly divisible by 400; so that only
every fourth centurial year is leap-year; thus, 1,700, 1,800, and 1,900
are common years, but 2,000, the fourth centurial year, is leap year, and
so on.
