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 1
  • 6 rotates to 9
  • 8 rotates to 8
  • 9 rotates to 6
  • 0 rotates to 0
