Forum:Are there really 104 days in Phineas and Ferb's Summer Vacation?

So are there really 104 days in summer vacation? Sure, the In real life, there's 104, maybe more, maybe less. But with 8-9 years in the runtime and finally capping the series with the Last Day of Summer, we can now question the (nearly a) decade-old statement of "There's a hundred and four days of summer vacation..."

So here's how its gonna go down: Out of all the numerous episodes that has aired, we will collate them and see if there are really 104 days of summer. However, since not all episodes that aired was in the summer timeline, we're gonna omit some of them. Like:


 * Episodes that takes place outside Summer (Christmas, Haloween, Doof 101)


 * Episodes that take place in alternate timeline (Excalifurb, Star Wars, Tales from the Resistance)

I'm gonna post my first set of results in a moment... of course we're gonna begin where it all began. Season 1.
