In accordance with what is applied in companies, we used the ISO-8601 standard to list the 2027 week numbers that appear in our first table.
According to this international standard, week 1 is that which contains the first Thursday of the year. Week N ° 1 can therefore start in December.
In addition, when New Years Day falls on a Thursday (Wednesday or Thursday for leap years), the year has 52 weeks, which is the case in 2020.
