Usually, the child stage will evolve to a teen after 24 hours. A teen will take 3 days for it to evolve to an adult. Then you have to wait for your adult to turn 6 years old(6 days old for people) for it to be married. OR if you have 2 V4's or V4.5 and they both have a very good relationship, then they can get married right away.(even if the V4 is a teen and the V4.5 is an adult and vice versa)
