I work on the 13th floor of an office building. Of course, it's occupied
by an engineering firm :-) PSOB

I read some a suggestion some years ago that we adopt a calendar with 13
months of four weeks each. 4x7x13=364. Add a new years day with the
appropriate leap day/year correction and you have a system where the the
nth day of the mth month is the same day of the week every year (if the
365th day is at the end of the year).
