Where 52 weeks shows up
Three hundred sixty-four, one day short of a common year and two short of a leap year, and that single day does more damage than its size suggests. It is why 26 biweekly pay periods do not fill a calendar year and employers periodically owe a 27th, and why fiscal calendars built on whole weeks need a 53rd week every five or six years. Fifty-two weeks is also the full statutory maternity leave entitlement in the UK, split into 26 weeks ordinary and 26 additional.
