The first time you start the Today & Tomorrow Channel, you will be asked to choose a Mii to represent yourself and enter your date of birth. Your date of birth determines the fortunes and lucky advice you receive, so please make sure you enter it correctly.
If you start the Channel without having any Mii characters registered, you will be asked whether you would like to register a Mii. Select YES to display the Mii Registration Screen. If you have already registered one or more Mii characters, your total luck for the day will be displayed when you start the Channel (see “6. Daily Fortunes”).
