Chicago Fire & Chicago Med Have Time Changes Tonight You Need to Know (Jan. 29)

Set your alarms, clocks, and timers, Chi-Hards: the One Chicago crossover episode is here! 

By Jessica White

Chi-Hards need no reminder that Wednesday nights on NBC mean new episodes of Chicago FireChicago P.D., and Chicago Med. However, those tuning in for the One Chicago crossover event on January 29 should note an important time swap happening. With a massive fire downtown kicking off this three-hour epic, airtimes for Chicago Fire and Med are switching. 

How to Watch

Watch Chicago Fire Wednesdays at 9/8c on NBC and next day on Peacock

For this week only, One Chicago Wednesdays will kick off with Chicago Fire, followed by Chicago Med, then Chicago P.D. This marks the first crossover event for the Chicagos since 2019, and fans couldn't be more excited to jump into the action. 

"You don't notice when you're going from one episode to the next," Chicago Fire showrunner Andrea Newman said. "It's really all one big episode. It's one big movie, is what it is... [The writers] really kept saying, 'We really want it to have layers that you just keep peeling back. Surprises that keep coming.' They made it together: a three-hour movie, essentially."
