# Method Calendar.YMD.Year()->week()

Method week

  ``Week` week()`
  ``Week` week(`int` `n`)`
  ``Week` week(`string` `name`)`

Description

  The Year type overloads the week() method, so it is possible to get a specified week by name:

  `year->week("17")` `year->week("w17")`

  The integer and no argument behavior is inherited from `YMD`().

  This is useful, since the first week of a year not always (about half the years, in the ISO calendar) is numbered '1'.
