! 1) convert date into 'model day', for yrflag=2,3,4 only.

! 2) for yrflag==4, all years are 365 days.

! so wday would be 1.0.
! b) iyr=1,mon=1,idy=2 is the 2nd day of the run,
! so wday would be 2.0.
!
! 3) for yrflag==3, the 'model day' is the number of days since
! 001/1901 (which is model day 1.0).
! for example:
! a) iyr=1901,mon=1,idy=1, represents 0000z hrs on 01/01/1901
! so wday would be 1.0.
! a) iyr=1901,mon=1,idy=2, represents 0000z hrs on 02/01/1901
! so wday would be 2.0.
! year must be no less than 1901.0, and no greater than 2099.0.
! note that year 2000 is a leap year (but 1900 and 2100 are not).
!
! 4) for yrflag==2, all years are leap years.
