Does anyone know when the final episode of Smallville will be?

I'd like to know so i can figure out a schedule to get caught up on seasons 5-10-so-far. If you have an idea at all that would be helpful. Like if they're going to take a break from showing it around Christmas, i know CW takes what seems like random breaks so i don't know if they'll be doing one shortly or not. or if it's gonna be every Friday until the final episode. If it'll be every Friday until the final episode, do you know when that would be? or how many episodes they'll have this final season?
