What made you go WTF today?

YYYY-MM-DD does work better for certain things, agreed, but for most casual organization the most useful unit is the month; you rarely need to worry about things from across many years, but you frequently deal with things across months. Day-to-day organization is not only useless because it keeps your organization down to a four week period, but also because most people don't think in day increments for files and the like. I'll admit it varies with the application, though. VERY rarely is DDMMYY(YY) useful, though.

As for Sunday, it's not a matter of being an 'advantage', it's a matter of following historical reality. Jews, Romans, and Christians all had Sunday as the first day of the week (I'm not clear what the Babylonians did, but it's not very relevant, now is it?). There's frankly no reason why ISO 8601 should have Monday as the first day of the week. It's like the French trying to switch to a decimalized calender back after the revolution.

I actually have to sort-of agree with wiggin here, though I've argued (in principle) in the past against the American system.

Since slash is not allowed as a marker in filenames and since day-to-day files don't need to be saved with year normally, the following is how I save a lot of my files:

07-25
07-26
07-28
07-29
07-30
07-31
08-01
08-02
08-03

It works better that way. I never save files dd-mm. The computer system does not sort files by date (if looking by filename) if they're done dd-mm.

Although preferably for most (especially weekly or non-daily files) I will save yy-mm-dd (I'm not planning to still be doing my current job in 2100 so screw yyyy). YYYY/MM/DD makes the most sense of all systems (you can still omit year if it is redundant). MM/DD/YYYY does not make sense logically in principle, or how its supposed to work after the change of year (especially with computers, I imagine old fashioned notebooks it would have been less of an issue).
