imports.ui.calendar

I made a datetime applet, and want to add a calendar in menu.

const Calendar = imports.ui.calendar;

this.menu = new Applet.AppletPopupMenu(this, orientation);
this.menuManager.addMenu(this.menu);
let calendar = new Calendar.Calendar();
this.menu.addActor(calendar.actor);

Error: No JS module 'calendar' found in search path
