datetime field overflow

Why would i get a "datetime field overflow" error ? Under what conditions ?
ThanksDATETIME data type can hold a date between January 1, 1753 and December 31,
9999. SMALLDATETIME can hold a date between January 1, 1900 and June 6,
2079. Trying to set a DATETIME column outside of these ranges will cause an
error.
