Can several addresses use the same date? Yes, each message is evaluated as they arrive.
Can the same address have several dates? Yes, each message is evaluated as they arrive.

What happens if I misspell the date? It depends in what way you spell it, as long as there is six and only six digits after the +, it will be compared to todays date. If there is another number of digits or something other than digits after the +, the message will be delivered to the account matching the name before the +.
