it is all relative.
most western calendars that i have seen show "Sun Mon Tue Wed Thu Fri Sat".
the concept of "first" day of week is a bit muddied.
many christian-influenced places would consider Sunday to be the "first"
day of the week, but monday being the "first" business day of the week.
i have seen calendars which use "Mon Tue Wed Thu Fri Sat Sun", and i have
worked with people where saturday was the first day of business. and also
places where sunday is the first day of business.
so, suffice to say, there is no "proper" first day of the week.
as such, the unix day of week pegs sunday as day 0, your code should just
use that index. since almost all cultures have now adapted to a 7 day week
and a 365 day year, there shouldn't bee too much confusion.
