Ready for the Blood Moon?

As you probably know, tonight is the beginning of Passover. You may also know that tonight we have a full moon -- and the full moon will experience a total eclipse, climaxing between 3:07 and 4:25 a.m. Eastern Standard Time tomorrow morning (April 15 -- income tax day!).

But did you know that the moon will appear to be red in color and that this is referred to as a "Blood Moon"? And even more rare: tonight's blood moon will be the first of four such full moons -- each appearing six months after the last one -- occurring through 2014 and 2015. Four blood moons are called a Lunar Tetrad and a Tetrad, according to the Bible, is what will happen to mark the end of days.

The sun will be turned to darkness, and the moon to blood before the great and dreadful day of the LORD comes.

(This theory has been publicized by Pastor John Hagee in his 2013 book Four Blood Moons: Something is About to Change.)

So are you ready for the end of the world?

Happy Passover! Pesach Sameach!

P.S. I don't really believe this, of course, but I'm always fascinated by superstitions and the way they are often shared by completely unrelated ethnic groups, and how they often seem to have roots in ancient pre-Christian times.

Here's one that I heard recently, first as a Greek superstition. Then I learned it was also a popular belief in Vietnam: If two siblings get married in the same year, one of those marriages will end in divorce.

But why?

Do you have any mysterious superstitions to share?
