48hrs after bieng adults they matchmaker makes visits.
10:30am
3:00pm
7:30pm
Though on the V4 depending when you bought it or when it was made it be aware that the matchmaker stays only for about 10 seconds.This is a bug though however it is fixed on the V4.5 and later made V4's.
Your V4 gets married when its either 5, 6, 7, or 8(i think). It usually won't get married when its 5 though. The matchmaker comes at different times. I know 2 right now, set the time to 2:59 pm and the matchmaker will come after 1 minute and if you set the time to 10:29am(i think) and wait a minute then it will come.
