That's correct. The only "invertable" digits, assuming a non-serif font, are 0, 1, 6, and 9. Thus the next common-era year that begins with an invertable digit would be in the 7th millennium, i.e. the 6000sm and the smallest possible invertable digit after 6 is 0.

Yes, it is true that the year 1961 reads the same upside down. The next year like this will be in 6009. This phenomenon occurs due to the symmetry of certain numbers when flipped.
