Week numbers are very useful for static holiday periods like the kid's school fall vacation and winter vacation. In my area, they are always in week 8 and week 40, and as such it's easier to plan accordingly. And my summer vacation is usually weeks 28-30. Just make sure to turn on week number in your calendar applications, then it might be more useful to you.
