At which point I wonder, why can't we be symmetrical and allow a function like:
make_date(2013, 2, 27); You could have these, instead, for more consistency:
make_date(2013, 45); make_date(2013, w7, fri); The later overload is Ok. The following is ambiguous
make_date(2013, 45);
and need
make_date(year(2013), 45); Right
BTW, do you prefer w7 or w_7? Or a literal 7_w instead of a constant object? I'd prefer at least "wk" if not "week" in the name. I don't think an underscore is nice there, and I don't like the literal ordering. Therefore, I'd like to see week7 or wk7.
Weeks? According to what way of counting weeks? Monday-weeks (Europe, ISO 8601), Saturday-weeks (Middle East), or Sunday-weeks (Canada, US, Mexico)?
If boost should adhere to ISO 8601, which I think it should, why not go all in and mandate ordering of YMD as well?

My opinions: 1) ISO week date says week as W07. So my suggestion was to not deviate too much from it: w7, W7 and W07 are all acceptable to me. w7 is the easiest to write among them so the first choice of mine. That is, if we mandate use of enums at all. Otherwise, sticking to week(n) is the cleanest option. 2) We should stick to ISO 8601 week standard, i.e. Monday weeks. They are not commonplace enough to warrant multiple notations. OTOH, the different day formats are actually followed in different countries, according to that useful link by Howard. My suggestion is to use ISo ordering only in functions like date() or make_date(). But when using slash, as in: date d = day(25) / dec / 2013; It is very natural to me. Here in my part of world, d-m-y is the dominant format. Otherwise use of '/' itself is of no much use.
