The latest gap between two palindromic years (A.D. assumed) was 11: 2002-1991.

When will occur the shortest gap :

a. within 500 years?
b. within 1000 years?
c. within 10000 years?

By use of the future tense (will occur), I am assuming that we are only considering future dates.

For A:  110 years.

2112-2222
2222-2332
2332-2442
2442-2552

For B:  11 years.

2992-3003

For C:  2 years

9999-10001
