After both people have graduated college and have started their careers. So maybe 25-30? I would think that getting married and potentially starting a family would distract from studies, so that's why I say after college.
It's probably better to wait until after both people have started their careers because what if she gets a job at Microsoft in Seattle and he gets a job at NBC in New York? Let's make sure both people have steady jobs in their respective fields so we know that nobody's going to move away.0
