A discovery

I was updating my planner last night, and made a cool discovery. I have known for a while that every year my birthday and Christmas fall on the same weekday. But what I had never realized is that New Years does too! My birthday was on a Friday this year, and Christmas and New Years will be on Fridays too! And next year, they are all on Saturdays! I don't know if the knowledge of that is useful, but it's rather fun knowing about it all the same.
