How week numbers work

Under the international standard ISO 8601, a week starts on Monday and week 1 is the week that contains the first Thursday of the year. This means 1 January can belong to the last week of the previous year, and a year has either 52 or 53 weeks.

2027 has 52 weeks and 365 days. It starts on a Friday and ends on a Friday.
