chmod +x mydate makes the script mydate executable. If you want to
run the script as root you can do it via ./mydate if you are in the
same directory or via full pathname like /path/to/mydate
If your script doesn't contain a she-bang (eg. #!/bin/sh in the first
line) you have to call it

    /bin/sh mydate

or

    /bin/sh /path/to/mydate

You'll get the complete explanation of chmod via

    man chmod
