Universal Palindromic Day and Two Digits Magic Squares

This work brings magic squares of orders 3 to 16 just for two digits 0 and 2 having the numbers 02022020, 20022020 and 22022020 representing respectively the dates 02.02.2020, 20.02.2020 and 22.02.2020. Also the the palindromic number 02022020, writing in reverse side becomes as 20200202, Writing in American style the last two dates are written as 02.20.2020 and 02.22.2020. Thus, there are total six numbers, 02022020, 20022020, 22022020, 20200202, 02.20.2020 and 02.22.2020. From 8th order onward, the magic square constructed brings these six numbers. For orders less than 8, only some of these six numbers appears in the magic squares. Most of the magic squares are upside down and mirror looking.
