In 7 consecutive years there will either be 1 or 2 leap years.

let L = leap year

and Y = non-leap year

If a leap year occurs every 4 years, the following are possible.

Y Y Y L Y Y Y

L Y Y Y L Y Y

Y L Y Y Y L Y

Y Y L Y Y Y L

There are more rules than " a leap year occurs every 4 years." 1900 was not a leap year, so 1897-1903 was such a span.
