Happy Friday the 13th!

I grew up hearing of a Friday the 13th in February as the unluckiest possible occurrence. But I can't remember where that superstition came from? And looking it up, I see nothing about it happening in February being particularly unlucky? My memory is that it's not a "true" Friday the 13th unless it happens in February. Did I dream that up?

Also, do the movies hold up? Haven't seen them
