A Definitive Timeline of Everything One Direction's Done Since the Hiatus

Since One Direction announced their extended hiatus in 2015, all four members — five if you count Zayn — have pursued solo careers, and so far they've all been decently successful. As *NSYNC fans know from experience, this is far from a given when a boy band takes a break. It's hard to say what the future will bring, but for now all five guys are thriving, and if you're trying to keep track of all of them, the mission gets harder and harder every day. Two of them have kids now, and three of them have had their debut solo albums hit number one! Can you even? Here, a complete history of everything the lads of 1D have gotten up to since they went their separate ways. Note: For the purposes of this exercise, Zayn will be included because (1) he didn't leave that long before they announced the hiatus and (2) he appears on four of the band's five albums.
