Quick Start Example

Here's a minimal working example to get started:

jsx

import React, { useState } from 'react';
import { DatePickerComponent } from '@syncfusion/ej2-react-calendars';
import '@syncfusion/ej2-base/styles/material3.css';
import '@syncfusion/ej2-buttons/styles/material3.css';
import '@syncfusion/ej2-inputs/styles/material3.css';
import '@syncfusion/ej2-popups/styles/material3.css';
import '@syncfusion/ej2-react-calendars/styles/material3.css';

export default function App() {
  const [selectedDate, setSelectedDate] = useState(new Date());

  return (
    <div style={{ padding: '20px' }}>
      <h3>Select a Date</h3>
      <DatePickerComponent
        value={selectedDate}
        change={(e) => setSelectedDate(e.value)}
        placeholder="Enter date"
      />
      <p>Selected: {selectedDate?.toDateString()}</p>
    </div>
  );
}

Key points:

Import

DatePickerComponent

from

@syncfusion/ej2-react-calendars

Import all required CSS themes (base, buttons, inputs, popups, calendars)
Use
```
value
```
prop for the current date (can be null or Date object)
Use
```
change
```
event (not
```
onChange
```
) to update React state — this is the Syncfusion event name
DatePicker opens a calendar popup on click or Alt+Down arrow

Common Patterns

1. Date Range Picker (Min/Max Dates)

jsx

<DatePickerComponent
  value={new Date()}
  min={new Date(2026, 0, 1)}
  max={new Date(2026, 11, 31)}
  placeholder="Select a date in 2026"
/>

2. Custom Date Format

jsx

<DatePickerComponent
  value={new Date()}
  format="dd/MM/yyyy"
  placeholder="DD/MM/YYYY"
/>

3. Multiple Accepted Input Formats

jsx

<DatePickerComponent
  value={new Date()}
  format="yyyy-MM-dd"
  inputFormats={['dd/MM/yyyy', 'yyyy-MM-dd', 'yyyyMMdd']}
  placeholder="Enter date (dd/MM/yyyy or yyyy-MM-dd)"
/>

4. Year/Decade View for Birth Date Selection

jsx

<DatePickerComponent
  value={new Date()}
  start="Decade"
  depth="Year"
  placeholder="Select year"
/>

5. Disable Weekends

jsx

<DatePickerComponent
  value={new Date()}
  renderDayCell={(args) => {
    if ((args.date.getDay()) === 0 || (args.date.getDay()) === 6) {
      args.isDisabled = true;
    }
  }}
  placeholder="Weekdays only"
/>

6. Controlled Component in React Form

jsx

const [date, setDate] = useState(null);

<DatePickerComponent
  value={date}
  change={(e) => setDate(e.value)}
  format="yyyy-MM-dd"
  strictMode={true}
  placeholder="Enter date"
/>

7. German Culture with RTL Support

jsx

<DatePickerComponent
  locale="de"
  enableRtl={false}
  firstDayOfWeek={1}
  value={new Date()}
  placeholder="Datum eingeben"
/>

8. Masked Date Input

jsx

<DatePickerComponent
  enableMask={true}
  format="MM/dd/yyyy"
  maskPlaceholder={{ day: 'DD', month: 'MM', year: 'YYYY' }}
  placeholder="Select a date"
/>

9. Programmatic Control

jsx

import { useRef } from 'react';

const datePickerRef = useRef(null);

// Open calendar
datePickerRef.current.show();

// Close calendar
datePickerRef.current.hide();

// Focus
datePickerRef.current.focusIn();

// Get current view
const view = datePickerRef.current.currentView(); // "Month" | "Year" | "Decade"

// Navigate to specific view
datePickerRef.current.navigateTo('Year', new Date(2026, 0, 1));

<DatePickerComponent ref={datePickerRef} value={new Date()} />

10. Handle All Key Events

jsx

<DatePickerComponent
  value={new Date()}
  change={(e) => console.log('Changed:', e.value)}
  focus={(e) => console.log('Focused')}
  blur={(e) => console.log('Blurred')}
  open={(e) => console.log('Opened')}
  close={(e) => console.log('Closed')}
  cleared={(e) => console.log('Cleared')}
  navigated={(e) => console.log('Navigated to view:', e.view)}
  renderDayCell={(args) => {
    // Disable weekends
    if (args.date.getDay() === 0 || args.date.getDay() === 6) {
      args.isDisabled = true;
    }
  }}
/>
