How many months is it advisable to be friends before dating?

I know it might not happen as I plan but I want to have all these stages of relationship this way.
Getting acquainted and start texting/calling on the 1st month
Becoming friends and start hanging on the 3rd month
Going on dates (start dating) and having the first kiss on the 6th month
Getting engaged on the 12th month
Getting married and having sex on the 18th month.
