If your OS supports the `std::locale("de_DE")` the above can be simplified to:
```c++
#include "date.h"
#include "tz.h"
#include <iostream>
#include "date.h"
#include "tz.h"
#include <iostream>
int
main()
{
using namespace date;
int
main()
{
using namespace date;
// create some gregorian objects to output
auto d1 = 2002_y/oct/1;
using namespace std;
locale loc("de_DE");
cout << format(loc, "%x\n", local_days{d1});
cout << format(loc, "%B\n", local_days{d1});
cout << format(loc, "%A\n", local_days{d1});
cout << format(loc, "%D\n", local_days{d1});
cout << format(loc, "%F\n", local_days{d1});
}
// create some gregorian objects to output
auto d1 = 2002_y/oct/1;
using namespace std;
locale loc("de_DE");
cout << format(loc, "%x\n", local_days{d1});
cout << format(loc, "%B\n", local_days{d1});
cout << format(loc, "%A\n", local_days{d1});
cout << format(loc, "%D\n", local_days{d1});
cout << format(loc, "%F\n", local_days{d1});
}
