For example, the 53 weeks of the poor case season 1976 come having 1975-12-29 = 1976-W01-step 1 and you will ended that have 1977-01-02 = 19eight6-W53-7. In addition, because of the reduced quantity of the very last few days away from a year, new terrible situation try a non-dive seasons including 1999 you to definitely starts with a friday, hence ensures that the original 3 days of the season fall-in on the last week of previous year. In this case, the fresh Weekend out of day 52 will be date number 3+52*7=367, i.e. just the history 367-365=2 days of your own W52 arrive at to the next season and you will thus, also a bad circumstances year such as for example 1999 features per week W52 like the days 1999-12-twenty seven in order to 2000-01-02. q.age.d.
