A userpage edit may not count. To be safe I'd edit a content page on the Wiki. If you're in the Eastern time zone, then yes, you need to edit before 8pm.

You are correct that it can be any time of day. And you are also correct that it will count as an edit for the next day IF it's after 8pm Eastern. You can keep track of your edits by looking on your Contribuations page. Remember to make sure that it's a page edit.
