A Date module

Hello!
What month is this month? Yes, it is an easy question for us.
So, how do we programme it with JavaScript? Yes, easy question again. We know we can use the "getMonth()" method.
Let's see a simple example below.

```html
<sample.html>

<div>This month is <span id="tmonth"></span></div>
<script>
  var tmonth = document.getElementById("tmonth");
  const datetime = new Date();
  tmonth.innerHTML = datetime.getMonth();
</script>
```

If you make this HTML file, you notice that this is bad. The getMonth() method returns a *number*! So, the result above is "This month is 11."
Wait a minute! This month is *December*. Why 11?
Yes, it is because the getMonth() method returns 0 to 11! This means that we have to add extra 1 to datetime.getMonth() above. That's too nasty I think!

Well, okay, December is 11. We want it to return "December", not 11. How should we do? The answer is simple:

```html
<sample.html>

<div>This month is <span id="tmonth"></span></div>
<script>
  var tmonth = document.getElementById("tmonth");
  const datetime = new Date();
  var monthname = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];       
  tmonth.innerHTML = monthname[datetime.getMonth()];
</script>
```

Actually, the day of the month returns 1 to 31 but the name of the week is same as the month and so the name of the weekday is, of course, implemented as above.
Every time we make a new application, we do this.
*It's nonsense!*


So, I made a module of this for you. Since I don't have any open repository on GitHub, please follow the itinerary below.

###Make Files

Firstly, you make a file: *datetime.js*.
Two, read the file in an HTML file.

###How to use

The module is just a JavaScript file. So, for example,

```html
<sample.html>

  <div>Today is <span id="date"></span>/<span id="month"></span>/<span id="day"></span>/<span id="year"></span></div>       
  <script>
    document.getElementById("day").innerHTML = day;
    document.getElementById("month").innerHTML = month;
    document.getElementById("date").innerHTML = date;
    document.getElementById("year").innerHTML = year;
  </script>
```

You can use for English: month, monthuppercase, datenumber, day, dayuppercase, dayshort, dayshortuppercase,
            
for Deutsche: monat, monatuppercase, monatnummer, wochentage, wochentageuppercase, wochentageshort, wochentageshortuppercase,

for French: mois, moisuppercase, moislowercase, moisnumero, jour, jouruppercase, jourlowercase, jourshort,

for Italian: mesi, mesiuppercase, giorni, giorniuppercase, giornishort, giornishortlowercase,

for Japanese: tsukikanji, tsukisuuji, tsukiishou, youbifull, youbihalf, youbishort,

commonly: year, monthnumber, date, hour, minute, second, millisecond.


###Comments

Any mistakes, all my fault. Your comment, your idea and what you want, very welcome! Safe journey!

###Module

Finally, you copy and paste the JavaScript codes below to the datetime.js.
