The year 1961 was rotationally symmetric.This means that if you turned 1961 upside down (180 degrees), it would still say "1961".The next time this will occur is in the year 6009.It only works with the following numbers:1 rotates to 16 rotates to 98 rotates to 89 rotates to 60 rotates to 0
6009-28767654 = -28761645
the year reads the same when turned upside down! it will happen again in 6009!
The year 1961 can be read upside down and that won't happen again until 6009
1961- this won't happen again until 6009. what about 2005?
