Valid Range for Gregorian Calendar 4714 B.C. to 9999 A.D.</para>
|
|
<para>
|
|
Although this function can handle dates all the way back to 4714
|
|
B.C., such use may not be meaningful. The Gregorian calendar was
|
|
not instituted until October 15, 1582 (or October 5, 1582 in the
|
|
Julian calendar). Some countries did not accept it until much
|
|
later. For example, Britain converted in 1752, The USSR in 1918
|
|
and Greece in 1923. Most European countries used the Julian
|
|
calendar prior to the Gregorian.
