Today marks the 18th anniversary of WordPress’ launch, a day that I fondly refer to as WordPress’ birthday, which means WordPress is 6,575 days old. To celebrate another turn around the sun, the community has had parties, we have shared data, and we have told our story.

Since our last birthday we developed our 40th release and now also support over 40% of the web. So it seems fitting that this year’s celebration should be a list of 40 milestones that have helped us get there.
