Number of a week within a year, from 1 to 53, sometimes written with a leading zero. Most years have 52 weeks. The rule for week 1 depends on the system; ISO 8601 weeks start on Monday and week 1 contains the first Thursday of the year. Data catalogs keep it in columns such as week, semaine or semana.
