It really isn't Christmas without watching Hermione, Ron and Harry grow up on screen in their Hogwarts robes.
Every year, we re-watch the trio take on different adventures and challenges.
Although it might be our hundredth time tuning into them, it could be the first time our big kids discover the magic of the movies.
Trying to watch them back-to-back can be a bit tricky, but RTÉ has helped us out and is airing all the movies over the festive season.
So you can cancel messing around with DVDs, streaming sites and tv schedules.
So here's what you need to know:
Harry Potter and the Philosopher’s Stone will be on Christmas Eve at 14:35 on RTÉ2.
Harry Potter and the Chamber of Secrets will be showing on Christmas Day at 15:40 on RTÉ2.
Harry Potter and the Prisoner of Azkaban will take to your screens on St Stephen’s Day at 15:25 on RTÉ2.
Sit back on St Stephen’s Day for a double bill, as Harry Potter and the Goblet of Fire will be on at 17:50 on RTÉ2.
Harry Potter and the Order of the Phoenix will be shown on December 27 at 15:20 on RTÉ2
Sticking with the magic, Harry Potter and the Half-Blood Prince will also be on December 27 at 17:45 on RTÉ2.
For the final instalments, Harry Potter and the Deathly Hallows: Part One and Two will be gracing our screens on December 28 at 15:45 and 18:15 on RTÉ2, respectively.
It's beginning to look a lot like Christmas.
