Hard as it is to believe you DO need to make most dining reservations 180 days out. This helps you get the special ones like Be our Guest, Cinderella’s Royal Table, California Grill, Chef Mickey and so many more!! Reservations start on line at 6 AM and you want to be there. To call in reservations that starts at 7 AM. These will link to your My Disney Experience App. I suggest using this calculator tool to know when your windows open (this can also be used for Fastpass selections): http://pscalculator.net/pscalc.php This is very helpful.
