I don't know how it wasn't brought to my attention sooner (to be honest, this is something I really should have been keeping tabs on my own) but this is, in fact, the day in which Skynet is expected to finally go online!
Skynet, of course, is the "fictional" computer artificial-intelligence software used within the Terminator film series.
According to the (what I can only assume) is the official Terminator wiki page:
April 19, 2011. At 20:11 Skynet goes online.
As a result of temporal interference by Sarah Connor, her son John, Miles Dyson, and the T-800 destroying Cyberdyne headquarters and all backups of the research in 1995, the date for Judgment Day is moved to two days after activation on April 21, 2011.
When this happens, this happens within the movie Terminator 2.
If for some strange sick reason you've never watched the film The Terminator before, get on it today! There's literally few better times to watch this series and be able to really feel like you're a part of the action. If you've watched the entire series a million times (more likely) and you're still wanting to get some sort of Terminator fix this week, you can always check out The Sarah Conner Connor Chronicles - which was a Fox television show that was on TV a few years ago.
