Swedes uses international standard for date and time representations. (See also SI for units.)
To set the record straight...:
Dates are written on format:
Time of the day is written
The week starts with Monday.
Week numbering is a great practice and
From Numeric representation of Dates and Time The ISO solution to a long-standing source of confusion.
Sweden, Japan, China + scientists, Swedes, and other really smart people around the whole world; computers, Internet (RFC-3339). Makes perfect sense!
|DD-MM-YYYY||Most of Europe (in common, daily use; ISO 8601/EN 28601 European Standard when it really counts), Canada, Mexico. Still logic and can at least be understood why.|
|MM-DD-YYYY||USA. Doesn't make any sense what so ever. Completely illogical. (It's like saying an item costs one hundred five, two thousand dollars. $2 105.)|
Eleven good reasons to use it - ISO-8601
|From Campaign to get the Internet World to use the International Date Format ISO 8601.|
In addition, ISO 8601 formally defines the "calendar week" often encountered in commercial transactions in Europe.
The first calendar week of a year: week 1, is that week which contains the first Thursday of the year (or, equivalently, the week which includes January 4th of the year; the first day of that week is the previous Monday).
The last week: week 52 or 53 depending on the date of Monday in the first week, is that which contains December 31 of the year.
The first ISO calendar week of a given year starts with a Monday which can be as early as December 29th of the previous year or as late as January 4th of the present; the last calendar week can end as late as Sunday, January 3rd of the subsequent year.
ISO 8601 dates in year, week, and day form are written with a "W" preceding the week number, which bears a leading zero if less than 10, for example February 29th, 2000 is written as 2000-02-29 in year, month, day format and 2000-W09-2 in year, week, day form; since the day number can never exceed 7, only a single digit is required. The hyphens may be elided for brevity and the day number omitted if not required. You will frequently see date of manufacture codes such as "00W09" stamped on products; this is an abbreviation of 2000-W09, the ninth week of year 2000.
"The ISO standard does not define any association of weeks to months. A date is either expressed with a month and day-of-the-month, or with a week and day-of-the-week, never a mix." [http://en.wikipedia.org/wiki/ISO_week_date#Weeks_per_month]
SwedeTeam uses a scheme following ISO-8601's handling of first week of year:
- First week of a month is week with at least 4 days in the month.
- This means the previous month can end on a Sunday with day 27 in previous month.

- Again, note that there are no (known to us) standards on this matter.
