Such, this new 53 days of bad instance season 1976 been that have 1975-12-29 = 1976-W01-1 and you will concluded with 1977-01-02 = 19eight6-W53-eight. Concurrently, due to the reduced number of the very last week regarding a year, new poor situation is a non-leap year such 1999 you to definitely begins with a saturday, which means that the original three days of the season fall-in on a week ago of your early in the day 12 months. In such a case, the new Week-end from month 52 could be go out #3+52*7=367, i.e. precisely the last 367-365=two days of your own W52 visited into the the following year and you will consequently, actually a bad situation 12 months instance 1999 possess each week W52 for instance the days 1999-12-twenty-seven so you’re able to 2000-01-02. q.elizabeth.d.
