Today's admin work (if you can call it still "admin work") is completely different: Writing YAML code for your automation tools, checking the CI/CD pipeline and deploying stuff to the cloud. The industry gave this kind of work the term "DevOps".
Classic sysadmins are an extinct species. Shouldn't this day therefore not better be called "DevOps Day"?
Happy SysAdmin Day :-)
All of this said, I think that people should consider changing or redirecting that wiki page for "Day of the Programmer" to "Day of the Developer" maybe.
