Variants exists for MM/DD/YYYY and DD/MM/YYYY (medium, smallest, biggest). No variant exists for YYYY-MM-DD, nothing to confuse.
The international standard is pretty old by now, I learned it as a child.
When sorting, the year is most important. Instead of everything published on the first in each month ending up at the start of the list, you get everything published today at the top.
