I really like Advent, which begins Sunday, because it helps me keep the focus of the Christmas season and also puts me in a frame of mind that prepares for Christmas that seems to help me appreciate it when it comes, rather than be relieved that the hoopla is over. Christmas is such an important holiday I want it to mean something, I want to enjoy it, I want to absorb it, and keeping Advent seems to do that.
We have an Advent calendar we've been using since I was a child that a neighbor made for us that includes a daily Bible reading and a hymn. Now I've also added an app for my iPhone that seems terrific. The graphics are really nice and the daily devotion provides a good chance to spend five minutes focused on Scripture and the promise God was working up to fulfilling in the Incarnation. The theology isn't focused on one system but is intentionally general enough for Bible-believing Christians.
There are other traditions you can adopt as an individual or family to recognize Advent and prepare for Christmas - traditional Advent calendar, an Advent wreath and candle, devotions. Plan to take time in these weeks to pause and focus on the season. It's a reminder to prepare for Christmas, but also for Jesus' second coming when we hope to be found alert and ready.
