Its so we can more easily look up things. So, when companies file things by date, to find it, they only have to remember the month it was filed, instead of the date, which can be difficult months and years later. Even if you don't remember the month, you can still think "it was in the summer" and so now, you can look over a period of 3 months to find it. If the date came first, all the months would be scattered when you organized them, and finding things would be difficult! So yeah.
I do agree you say july 30th idk about other english speaking countries but in spanish u say 30 of july so it is 30/7/2014 for example. But yeah americans no offense do a lot thinking it is so normal when they are the minority or maybe only ones....metric system for example...
That actually is why we (and several other countries that always get ignored) do month/day/year. People used to always write out the date, and although you may say "4th of July" nobody would ever write it out like that, its July 4th, 2014. Then people wanted to shorthand it, so they kept the same convention and it changed to 7/4/14
There are quite a few benefits to the imperial units. Take the foot for example, you can divide it evenly into 1/2, 1/3, 1/4, and 1/6. Metric you can only divide into 1/2 or 1/5. The only reason metric is so popular is because so many other people use it and its all base 10, which is easy for dumb people to handle since they have 10 fingers.
4th of July
People like you think us Americans are ignorant.
A day is in a month
