You're wrong. According to the calendar FAW (thanks, Google:-):

5.7 What is the week number? 

International standard IS-8601 (mentioned in section 5.6) assigns a number to each 
week of the year. A week that lies partly in one year
and partly in another is assigned a number in the year in which most of its days lie. 
This means that 

    Week 1 of any year is the week that contains 4 January, 

or equivalently 

    Week 1 of any year is the week that contains the first Thursday in January. 

Most years have 52 weeks, but years that start on a Thursday and leap years that start 
on a Wednesday have 53 weeks.
