A year is the space of time in which the sun runs through all the 12 signs of the zodiac: containing 12 solar months, 13 lunar months, 52 weeks, 365 days, and six hours, which six hours, in four years time, being added together, make one day, which day on every fourth year is added to February, making that month 29 days, which at other times is but 28; and this year with the additional day is called leap-year.

To find the Leap-Year.

Divide the year of our Lord by 4, and if there be no remainder, it is leap-year; but if there remains 1, 2, or 3, then that denotes the first, second, or third after leap-year.
