I have two date variables in my dataset. They show the beginning and end dates of a person's leadership. My data is like this:

Code:
           
person             startdate         enddate
A                  28/12/2000    21/12/2004
B                  27/09/1962    05/11/1967
C                  17/11/1993    08/06/1998
D                  18/11/1958    01/11/1964
E                  02/04/2000    31/12/2004
F                  01/01/1996    31/12/2004
Now I want to create a year variable that shows each year in which a person has the leadership position. For example, for person A, the data should be like this:

Code:
person       Year
A             2000
A             2001
A             2002
A             2003
A             2004
I'd appreciate if anyone could help.
