Dates are not a built-in Fortran data type, but it is not difficult to manipulate them. There are some links to codes for this at http://www.dmoz.org/Computers/Programming/Languages/Fortran/Source_Code/ -- search "date". Numerical Recipes also has code to handle dates. In Fortran 90 and later versions, one can define a data type such as type, public :: date_mdy integer :: month integer :: day integer :: year end type date_mdy along with associated functions to compute the day-of-week, next day, etc. I have done this.
