Ideally, the calendar week layout should respect the convention of the current locale (e.g., en_US -> SMTWHFS, es_ES -> MTWHFSS), but the Evolution preference "Calendars and Tasks -> Work Week -> Week starts" ought to override it -- or there should be some other facility for configuring the beginning of the work week.
Either way, it's not critical, but requiring a Sunday-first or Monday-first week for everyone is pretty much guaranteed to annoy someone. Mine was showing Saturday-first for a while. After a recent dist-upgrade, it's back to Monday-first, which, while not appropriate for my locale (en_US), is at least one I've encountered before :-) cmr
