I don’t have any cool dates on my calendar for this year, but I can punt.
Today is Mother’s Day! We can celebrate even without great numbers.
Five and Fourteen don’t get along very well. Come back next year because 5 and 15 have a great relationship!
5/11/14 through 5/17/14: 11, 12, 13, 14, 15, 16, and 17… each is one number larger than the previous!
And 5/15 is the Ides of May. Some Roman or Greek or somebody was probably assassinated that day, although it is not as popular as the Ides of March.
