Sure there is, within the tradition I was refering to.
Within that tradition, the start of the week isn't arbitray.

Besides, the documentation specifically says it's using
the European system

<quote>
By default, these calendars have Monday as the first day
of the week, and Sunday as the last (the European convention).
Use setfirstweekday() to set the first day of the week to
Sunday (6) or to any other weekday.

So, by default, Python doesn't use the American convention
of weeks starting on Sunday (an American technicality).
This does not contradict what I said.

Amongst different systems, it's never arbitrary within a system.

I know, that's why I added the caveat.

The accounting software I use to fill out my timesheet
electronically was obviously created by IT people and
the week begins on Monday. Their will is, of course,
forced on all employees whether they are IT or not.

Last time I was in Borders, I don't recall seeing any
Polish, Lithuanian or Chinese calendars for sale.
