## API
There are five kinds of picker:
- DatePicker
- DatePicker\[picker="month"]
- DatePicker\[picker="week"]
- DatePicker\[picker="year"]
- DatePicker\[picker="quarter"] (Added in 4.1.0)
- RangePicker
### 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](https://ant.design/components/config-provider/).
If there are special needs (only modifying single component language), Please use the property: local. Example: [default](https://github.com/ant-design/ant-design/blob/master/components/date-picker/locale/example.json).
```jsx
import 'dayjs/locale/zh-cn';
import locale from 'antd/es/date-picker/locale/zh_CN';
<DatePicker locale={locale} />;
```
```jsx
// The default locale is en-US, if you want to use other locale, just set locale in entry file globally.
import dayjs from 'dayjs';
import 'dayjs/locale/zh-cn';
import locale from 'antd/locale/zh_CN';
<ConfigProvider locale={locale}>
<DatePicker defaultValue={dayjs('2015-01-01', 'YYYY-MM-DD')} />
</ConfigProvider>;
```

## FAQ
### When set mode to DatePicker/RangePicker, cannot select year or month anymore?
Please refer [FAQ](/docs/react/faq#when-set-mode-to-datepickerrangepicker-cannot-select-year-or-month-anymore)
### How to use DatePicker with customize date library like dayjs?
Please refer [Use custom date library](/docs/react/use-custom-date-library#datepicker)
### Why config dayjs.locale globally not work?
DatePicker default set `locale` as `en` in v4. You can config DatePicker `locale` prop or [ConfigProvider `locale`](/components/config-provider) prop instead.
#### Date-related components locale is not working?
See FAQ [Date-related-components-locale-is-not-working?](/docs/react/faq#date-related-components-locale-is-not-working)
### How to modify start day of week?
Please use correct [language](/docs/react/i18n) ([#5605](https://github.com/ant-design/ant-design/issues/5605)), or update dayjs `locale` config:
- Example: <https://codesandbox.io/s/dayjs-day-of-week-x9tuj2?file=/demo.tsx>
```js
import dayjs from 'dayjs';
import 'dayjs/locale/zh-cn';
import 'dayjs/plugin/updateLocale';
dayjs.updateLocale('zh-cn', {
weekStart: 0,
});
```
### Why origin panel don't switch when using `panelRender`?
When you change the layout of nodes by `panelRender`, React will unmount and re-mount it which reset the component state. You should keep the layout stable. Please ref [#27263](https://github.com/ant-design/ant-design/issues/27263) for more info.
