Per the reasoning here, the seventh and eighth episodes of The Bad Batch Season 2, "The Clone Conspiracy" and "Truth and Consequences," can be placed in 18 BBY. Therefore, all Season 2 episodes proceeding "The Clone Conspiracy" occur between 19 BBY, which features the end of The Bad Batch Season 1 according to Star Wars: Timelines, and 18 BBY. The Galactic Empire, the formation of which Star Wars: Timelines dates to 19 BBY, sent Mayday's squad to Barton IV over a year prior to the events of the twelfth episode, "The Outpost." As it occurs over a year into the Imperial Era and is set shortly after the events of "Truth and Consequences," the events of "The Outpost" occur around 18 BBY. Following that logic, the ninth through eleventh episodes ("The Crossing" through "Metamorphosis") are also set around 18 BBY because they occur between the events of "Truth and Consequences" and "The Outpost." Finally, all season 2 episodes set after "The Outpost" occur shortly after its events, thereby placing those episodes around 18 BBY as well.
