Today is Friday the 13th, an unlucky day according to Western superstition.
Not sure why it is unlucky so I looked it up in Wikipedia. The number 13 is irregular, an extra 1 for 12, which is a complete number (12 months, 12 disciples, 12 tribes). 13 is also a prime number. Friday is considered an unlucky day. So 13 + Friday is a very unlucky combination. There's even a word to describe the irrational fear of Friday the 13th - paraskevidekatriaphobics. There are people who wouldn't drive or go out from the house or buy properties on this day.
Of course I don't believe in that. :-)
Today is Friday, it's the day of preparation for the Sabbath, it's the day when Jesus was nailed on the cross and His blood was shed for us.
Today is Friday the 13th, I have no fear, because the number will not stop God from loving me.
