When using d3.time.format(%Y%W) it doesn't give the expected output.
d3.time.format("%Y%W").parse("201553")
outputs
Mon Jan 04 2016
Although the first Monday of week number 53 in 2015 is Mon Dec 28 2015
So it seems like it parses to the next week.
Any ideas how to fix this to get the expected output.
