A Palindrome Year happens when the year date can be read the same way backwards and forwards.
The numbers are similar to word palindromes in that they are symmetrical.
In binary 2015 = 11111011111 so...
We made a folded greeting card. Inside the left side we wrote 11111 and the half of a 0. On the right side there is a « mirror paper ».
When you open the card, the mirror paper on the right side reflects the numbers of the left side in order to read the second half of the 0 and 11111.
When you look at the 2 sides you can read 11111011111, which mean 2015 in binary!
Happy New Year everybody!
