------------------------------------------------------------------------------

 Syntax

      FT_EASTER( <xYear> ) -> dEdate

 Arguments

     xYear can be a character, date or numeric describing the year
     for which you wish to receive the date of Easter.

 Returns

     The actual date that Easter occurs.

 Description

     Returns the date of Easter for any year after 1582 up to Clipper's
     limit which the manual states is 9999, but the Guide agrees with
     the actual imposed limit of 2999.

     This function can be useful in calender type programs that indicate
     when holidays occur.

 Examples

     dEdate := FT_EASTER( 1990 )     && returns 04/15/1990
