Question

-------------------------------------------------------------------
How do you read it?

1. October twelfth, twenty blah blah
2. October twelfth, twenty asterisk asterisk
3. October twelve, twenty blah blah
4. October twelve, twenty asterisk asterisk

Answer 1

1 or 3 will work fine
some would also say "twenty-something"

no one really ever says "asterisk" when seeing one in print. (In fact, many mispronounce it as "asterik" or "asterix")
