In Germany (and afaik in many other European countries), it is VERY
common to do industrial planning in calendar weeks. You will often
hear here things like "this device will be delivered in the 32nd
calendar week". Most calendars you can buy here show these week
numbers.

The system used in Europe is as specified in the international
standard ISO 8601: A weeks starts with Monday (day 1) and ends with
Sunday (day 7). Week 1 of a year is the first week which has the
majority of its seven days in the new year, in other words, week 1 of
the year 1996 is the week which contains the first Thursday of 1996.

If you want to know more about ISO 8601 (International Standard Date
and Time Notations), please have a look at
