    Usage: sh $0 YYYY MM <full path of script to run and arguments>"

    Calculate number of days in month given year and date.
    Call run_merra24.sh in screen to run full month.

    YYYY:  use 4-digit date to reduce error in figuring out century.
    MM:    1 or 2-digit month number
    script_path:  Script to run that takes a date as first argument (provided
                  by this code) and any arguments for the secondary script.

    Suggestion:  If only a few days are needed run_merra24.sh directly.
