Thirty days hath September,
April, June, and November ;
February hath twenty-eight alone,
And all the rest have thirty-one ;
Except in Leap Year, then's the time,

When February's days are twenty-nine. Leap Year happens every 4th year, and is known by dividing the year by 4, and if there be no remainder, that year is Leap Year.

The Tropical or Solar Year is usually reckoned at 3654 days ; but its accurate length, as determined from astronomical observations, is 365 days, 5 hours, 48'48”.

A Century is 100 years.
