I run Date.new(2000,1,1).cweek, the result is 52.

My Ruby version is 2.1.1

This looks like correct behaviour. From a previous issue #9372:

A period of time of seven days within a calendar year, starting on a
Monday and identified by its ordinal number within the year; the first
calendar week of the year is the one that includes the first Thursday
of that year.
