Updated with Season 10 of The Walking Dead, the finale for which will air later this year, as well as the premiere of The Walking Dead: World Beyond.

Several years ago, I worked on a project for AMC called The Walking Dead: The Journey So Far. It was a two-hour special summing up The Walking Dead ahead of the Season 7 premiere. While working on that project, me and the other producers decided it would be fun to come up with a timeline for the events of TWD. And it was fun - until we tried to factor in where the events took place and how long it took to get to each made-up destination. The experiment ended in frustration, anger, and tears.

Now I'm trying again, and leaving travel time out of it. The following timeline captures the major moments and milestones of The Walking Dead universe, including the events of the spinoff series Fear the Walking Dead. The timeline is arranged by day because in the zombie apocalypse, no one has any use for calendars.
