Calendar or Schedule

My idea would be for a calendar or schedule to mark the times you normally play online so you might find people that play the same times as you. For example, with my kids, I usually play 8 pm - 10 pm Eastern. If I could mark that to find other people that are usually online at that time to help coordinate playing some games together across time zones without having to do the conversions in my head.
