There are mods that extend the timeline, but you don't get achievements when you use them and you must start a new campaign with them.

The tools that I know about are: pdx.tools[pdx.tools](formerly rakaly. to de-ironman, select your ironman save, let it be analyzed and then click on the "i" icon on the right and then on "Melt" in the top-right corner), Pdx-Unlimiter[github.com], skanderbeg[skanderbeg.pm], paperman[gitgud.io](give it your eu4.exe to update the converter for your game version), a trick to make eu4 convert the save game, ironmelt[codeofwar.wbudziszewski.pl](defunct). They are somewhat ordered by how good they work with the current game version.

But if you just want to continue past 1821, you can just use the following mod:

It can even be activated for an ongoing campaign which already reached the end screen
