Usage

Basic Usage

import NepaliDateConverter from "antd-date-picker-nepali";

// Get today's date in Nepali calendar
const todayNepali = NepaliDateConverter.getTodayBs();

Then, you can use the Nepali date picker component in your React project as follows:

import React from 'react';
import { NepaliDatePicker } from 'antd-date-picker-nepali';
import 'antd/dist/antd.css';

const App = () => {
  const onChange = (date: any, dateString: string) => {
    console.log(date, dateString);
  };

  return (
    <div>
      <h1>Nepali Date Picker</h1>
      <NepaliDatePicker onChange={onChange} />
    </div>
  );
};

export default App;

Components

NepaliDatePicker

The NepaliDatePicker component supports all the same props as the Ant Design DatePicker component. Please refer to the Ant Design DatePicker documentation for detailed information.

Here is an example of how to use the NepaliDatePicker component with additional props:

import React from 'react';
import { NepaliDatePicker } from 'antd-date-picker-nepali';
import 'antd/dist/antd.css';

const App = () => {
  const onChange = (date: any, dateString: string) => {
    console.log(date, dateString);
  };

  return (
    <div>
      <h1>Nepali Date Picker</h1>
      <NepaliDatePicker
        onChange={onChange}
        placeholder="Select date"
        format="YYYY-MM-DD"
        showToday
      />
    </div>
  );
};

export default App;

NepaliRangePicker

The NepaliRangePicker component supports all the same props as the Ant Design RangePicker component. Please refer to the Ant Design RangePicker documentation for detailed information.

Here is an example of how to use the NepaliRangePicker component with additional props:

import React from 'react';
import { NepaliRangePicker } from 'antd-date-picker-nepali';
import 'antd/dist/antd.css';

const App = () => {
  const onChange = (dates: any, dateStrings: [string, string]) => {
    console.log(dates, dateStrings);
  };

  return (
    <div>
      <h1>Nepali Range Picker</h1>
      <NepaliRangePicker
        onChange={onChange}
        placeholder={['Start date', 'End date']}
        format="YYYY-MM-DD"
        showTime
      />
    </div>
  );
};

export default App;
