The CW has announced its premiere dates for 2017, and there are going to be a few shakeups. Let’s go through it day by day: Mondays will remain largely intact with Supergirl and Jane the Virgin. Tuesdays, Legends of Tomorrow will be moving into the post-Flash spot left by No Tomorrow (after its season finale), while The 100 returns to Wednesdays after Arrow (as soon as Frequency wraps its first season).

Supernatural is then taking an early slot on Thursdays at 8 p.m. to lead into Riverdale, which is a little bit of an odd choice but we’ll go with it. Reign will then fill that Friday slot after The Vampire Diaries (which will end its series run on Friday, March 10th).

In the spring, The Originals will take over the Friday spot from The Vampire Diaries, and iZombie will kick off with back-to-back episodes on Tuesday, April 4th before settling in to a regular timeslot after the Flash (meaning that Legends of Tomorrow will have finished up its extended season).

Got that all straight? It’s interesting that The CW is doubling down on The Flash and Legends on Tuesdays for a little while, since it has allowed each series to stay on its own day before this. But, with The Flash bringing the best ratings to The CW, there’s  surely a hope that it might offer a boost to legends if viewers then stick around for it as well. Thursdays will be an interesting night after that swap, too, since using Supernatural as a launch series at 8 p.m. for Riverdale at 9 p.m. (on an already very competitive night) is not an intuitive pairing.

The CW is not afraid to mix up their schedule, this is certain, but we’ll see what that ends up meaning for their ratings this spring.

Here is the full schedule to help you keep track of the changes. And you catch up with other TV Premiere dates with our calendar.
