The Date Shift cipher is a much harder code to break than, for example, the more simple Shift cipher.

If you've got KIDS AT HOME, I can do all the teaching for you so you can take a break! Go here for more hands-on math and science lessons: www.SuperchargedScience.com/school | Supercharged Science a
