Each month has 4 or 5 complete weeks. The month start or end is determined by applying the ISO Thursday rule to the week at the month border. For example, in the ISO calendar, the month of October 2012 ends on Sunday, October 28, because Thursday in the border week falls on November 1. The new week that begins on Monday, October 29, becomes part of November.
