#### Internationalization

The default `i18n` configuration format looks like this:

```javascript
i18n: {
    previousMonth : "Previous Month",
    nextMonth     : "Next Month",
    months        : ["January","February","March","April","May","June","July","August","September","October","November","December"],
    weekdays      : ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"],
    weekdaysShort : ["Sun","Mon","Tue","Wed","Thu","Fri","Sat"]
}
```

## Usage

#### Simple datepicker:

```javascript
{
  type: "pikaday",
  label: "Simple datepicker",
  placeholder: "User's birth of date",
  model: "date",
  validator: validators.date,  
  pikadayOptions: {
    position: "top left"
  }
}
```
