Date column

["Overstreet, Jason (FL51)" <Jason.Overstreet@honeywell.com>]

I am trying to use the date given in a column listed in a data frame to create a factor in another column.  In this case, I have the following:

Date1

05/01/1990

06/02/1995

07/03/2001

08/03/2003

I would like to create a corresponding column that tests the Date1 column and creates a variable in another column that states either “Twentieth Century” or “Twenty-First Century” based on the value in Date1.

Desired output:

 Date1                  Period

05/01/1990              Twentieth Century

06/02/1995              Twentieth Century

07/03/2001              Twenty-First Century

08/03/2003              Twenty-First Century

Thanks in advance…
