What week is it now?
Weeks in a Gregorian calendar year can be numbered for each year. This style of numbering is commonly used (for example, by schools and businesses) in some European and Asian countries, but rare elsewhere.
ISO week date system
ISO 8601 includes the ISO week date system, a numbering system for weeks. Each week begins on a Monday and is associated with the year that contains that weeks Thursday (so that if a year starts in a long weekend Friday - Sunday, week number one of the year will start after that).
First day of week
