[1960..1969] has precision of 1 year. When we say 1960 we are specifying a
date with a precision of year. Saying that a date is within some range does
not change the precision.
We want, however, another precision. That is what the 196 you suggested
This could let us do things (using now your notation): [196..199]
My suggestion was to make it some consistent and allow our focus of a
decade, for example, to be shifted to a middle point elsewhere..
Think about statements like "Mid 18th century"...
