The Cursed Child is set with an Adult Harry.
Wikipedia says this
it was confirmed the plays were set nineteen years after the conclusion of the final novel.
This BBC article 'clarifies':
It will pick up the story 19 years after Harry was last seen in Harry Potter and the Deathly Hallows, waving his two eldest children off to Hogwarts.
So by reckoning.
- Philosophers stone was set in 1991
- Each book represents a year. + 7 Years
- The epilogue to Deathly Hallows + 19 Years
- + 19 years quoted in the articles above
Is this correct, is it verified anywhere that it is set in the future? Would this be a first for Harry Potter?
