The CW is not airing this year’s Arrowverse crossover in one week. Instead, the “Crisis on Infinite Earths” specials will be split with a month-long hiatus in the middle.

According to the release date announcement made at the Television Critics Association tour on Sunday, the crossovers will start to premiere in December with three episodes. “Supergirl” will kick things off on Sunday, Dec. 8 while “Batwoman” moves to Monday to continue the event on Dec. 9. “The Flash” will wrap up the 2019 portion of the crossover on Tuesday, Dec. 10.

After that, fans have a month-long hiatus through the winter holidays. “Crisis on Infinite Earths” will return in the new year to come to an end on Tuesday, Jan. 14. “Arrow” will air at 8 p.m. EDT followed by “DC’s Legends of Tomorrow,” which is counting this as a special episode rather than the season premiere.

That means “Arrow” will not end in the fall, despite a shortened final season. The show that launched The CW’s DC TV universe is ending with a 10-episode eighth season. This schedule indicates that the series finale won’t air until 2020.

“Crisis on Infinite Earths,” confirmed in last year’s “Elseworlds” crossover, is going to be a huge event. All the superheroes are coming out for this one. Tyler Hoechlin’s Superman will be there as will Brandon Routh’s Kingdom Come version of the Man of Steel.

According to TVLine, the specials will also include “Black Lightning” star Cress Williams, marking the first time that DC show has crossed over with the others.

Additionally, Kevin Conroy will appear in the Arrowverse crossover as “Bruce Wayne from the future.”

“Crisis on Infinite Earths” has been teased since the very beginning of “The Flash” where a newspaper headline warned that Barry Allen (Grant Gustin) disappears during a “crisis.” The seventh season of “Arrow” ended with Oliver (Stephen Amell) leaving his family behind to fulfill his deal with the Monitor (LaMonica Garrett) and warn other Earths of the coming threat.

All the CW’s DC TV shows are expected to keep building up to the crossover. Most of the Arrowverse shows will return in October.
