You don't need to "remember" the release date. It's stored in every pages history. Address bar: http://percyjacksonfanfiction.wikia.com/index.php?title=[INSERTPAGETITLEHERE]&action=history

Then you can either use the date found at the bottom of the article (which would be when it was created) or find when the article went from "in progress" to "released", which would be shown by the bytes of data in the article increasing from something like 10 or 50 bytes to thousands of bytes. (You can also preview previous versions of the article to check)
