## API

There are four kinds of picker:

- DatePicker
- MonthPicker
- RangePicker
- WeekPicker

### Localization

The default locale is en-US, if you need to use other languages, recommend to use internationalized components provided by us at the entrance. Look at: [ConfigProvider](http://antdv.com/components/config-provider/).

If there are special needs (only modifying single component language), Please use the property: local. Example: [default](https://github.com/vueComponent/ant-design-vue/blob/master/components/date-picker/locale/example.json).

```html
<template>
  <a-date-picker :locale="locale" />
</template>
<script>
  import locale from 'ant-design-vue/es/date-picker/locale/zh_CN';
  export default {
    data() {
      return {
        locale,
      };
    },
  };
</script>
```

**Note:** Part of locale of DatePicker, MonthPicker, RangePicker, WeekPicker is read from value. So, please set the locale of moment correctly.

```html
<template>
  <a-date-picker :defaultValue="moment('2015-01-01', 'YYYY-MM-DD')" />
</template>
<script>
  // The default locale is en-US, if you want to use other locale, just set locale in entry file globally.
  import moment from 'moment';
  import 'moment/locale/zh-cn';
  export default {
    data() {
      return {
        moment,
      };
    },
  };
</script>
```
