Week numbering

Picture: Dan Moyle
First of all, I wish everyone a happy 2014! As the new year begins, we start using and/or organising a new calendar.

At work we have several discussions during the year about week numbers. Collegaes state that a particular date is in a certain week, in théir calendar. Others disagree. But who's right?

In many e-mail and calendar applications, one has to choose the weeknumbering. Options for Week 1 are:
  1. the week of January 1st,
  2. the first week with at least four days in the new year and
  3. the first full week in the new year.

In the Netherlands - where I live - option 2 is correct. Ergo, Week 1 is the first week with at least four days in the new year.

Good luck!
