Even though this is a closed issue, I am seeing the same issue for the years 2018 and 2019:

`[1] pry(#<Object>)> date = Date.new(2018,12,31)
=> #<Date: 2018-12-31 ((2458484j,0s,0n),+0s,2299161j)>
[2] pry(#<Object>)> date.cweek
=> 1
[3] pry(#<Object>)> date = Date.new(2019,12,31)
=> #<Date: 2019-12-31 ((2458849j,0s,0n),+0s,2299161j)>
[4] pry(#<Object>)> date.cweek
=> 1`

Can this same issue apply for two calendar years in a row?
