Yes, the matchmaker will normally come when your tama is either 6 or 7 years old. ^_^
But it depends on what age your tama was when it evolved into an adult.
It will need to be an adult for a total of 48 unpaused hours - day & night.
Once, the matchmaker didn't come until my tama was 11 - because it evolved into an adult at 9 years old. ^_^
