Seems like the age is right. The matchmaker will come 3 times a day at 10:30am, 3pm, and 7pm around 3 days after your Tamagotchi turns into an adult. If you want the matchmaker to come right now, set the time to a minute before any of the normal matchmaker times and wait a minute and she should come. ^^ This will only work, of course, if your Tamagotchi is at the right age. And it seems like yours should be.
