Was keyboard support implemented in the custom datepicker?

Yes, custom datepicker was implemented with keyboard support to improve accessibility and ease of use.

Implemented:

• Navigation between days using arrow keys (left, right, up, down).
• Selecting a date with the Enter key.
• Quick transition between months using PageUp and PageDown.
• Closing the calendar with the Escape key.

Example of handling keyboard events in JavaScript:

datepickerElement.addEventListener('keydown', (event) => {
  switch(event.key) {
    case 'ArrowLeft':
      moveFocusToPreviousDay();
      break;
    case 'ArrowRight':
      moveFocusToNextDay();
      break;
    case 'Enter':
      selectFocusedDate();
      break;
    case 'Escape':
      closeDatepicker();
      break;
    // other keys
  }
});

This allows users to work efficiently with the calendar without a mouse.
