Dependency

The latest version has below dependency:
intl 1.2.5, due to issue https://github.com/angular/angular/issues/3333

Usage

Install: npm install ionic2-calendar --save

Import the ionic2-calendar module:

import { NgModule } from '@angular/core';
import { IonicApp, IonicModule } from 'ionic-angular';
import { MyApp } from './app/app.component';
import { NgCalendarModule  } from 'ionic2-calendar';


@NgModule({
    declarations: [
        MyApp
    ],
    imports: [
        NgCalendarModule,
        IonicModule.forRoot(MyApp)
    ],
    bootstrap: [IonicApp],
    entryComponents: [
        MyApp
    ]
})
export class AppModule {}

Add the directive in the html page

      <calendar [eventSource]="eventSource"
        [calendarMode]="calendar.mode"
        [currentDate]="calendar.currentDate"
        (onCurrectDateChanged)="onCurrentDateChanged($event)"
        (onRangeChanged)="reloadSource(startTime, endTime)"
        (onEventSelected)="onEventSelected($event)"
        (onTitleChanged)="onViewTitleChanged($event)"
        (onTimeSelected)="onTimeSelected($event)"
        step="30">
      </calendar>

Note for Ionic Build/Run command

ionic serve uses tsc to compile the code, while ionic build/run uses ngc to compile the code.
It requires explicit dependency on the compiled ngfactory files for each component.
I couldn’t find a way to configure the build command includes the ngfactory of the child components automatically.
So the workaround is to import them explicitly.
Add below lines in main.prod.ts

import { CalendarComponent } from 'ionic2-calendar/calendar';
import { MonthViewComponent } from 'ionic2-calendar/monthview';
import { WeekViewComponent } from 'ionic2-calendar/weekview';
import { DayViewComponent } from 'ionic2-calendar/dayview';

  Default value: true

• startingDayMonth
  Control month view starting from which day.
  Default value: 0

• eventSource
  The data source of the calendar, when the eventSource is set, the view will be updated accordingly.
  Default value: null
  The format of the eventSource is described in the EventSource section

• queryMode
  If queryMode is set to 'local', when the range or mode is changed, the calendar will use the already bound eventSource to update the view
  If queryMode is set to 'remote', when the range or mode is changed, the calendar will trigger a callback function rangeChanged.
  Users will need to implement their custom loading data logic in this function, and fill it into the eventSource. The eventSource is watched, so the view will be updated once the eventSource is changed.
  Default value: 'local'

• step
  It can be set to 15 or 30, so that the event can be displayed at more accurate position in weekview or dayview.
  Default value: 60

        var current = new Date();
        return date < current;
    };
  

• onCurrentDateChanged

    };
  

• onRangeChanged

  The ev parameter contains two fields, startTime and endTime.

    <calendar ... (onRangeChanged)="onRangeChanged($event)"></calendar>
  
    onRangeChanged = (ev: { startTime: Date, endTime: Date }) => {
        Events.query(ev, (events) => {
            this.eventSource = events;
        });
    };

View Customization Option

Note: For any css class appear in the customized template, you need to specify the styles by yourself. The styles defined in the calendar component won’t be applied because of the view encapsulation.

• monthviewDisplayEventTemplate
  Type: TemplateRef<IMonthViewDisplayEventTemplateContext>
  The template provides customized view for event displayed in the monthview

    <template #template let-view="view" let-row="row" let-col="col">
        {{view.dates[row*7+col].label}}
    </template>
  
    <calendar ... [monthviewDisplayEventTemplate]=“template”></calendar>
  

• monthviewEventDetailTemplate
  Type: TemplateRef<IMonthViewEventDetailTemplateContext>
  The template provides customized view for event detail section in the monthview

    <template #template let-showEventDetail="showEventDetail" let-selectedDate="selectedDate" let-noEventsLabel="noEventsLabel">
    ... 
    </template>
  
    <calendar ... [monthviewEventDetailTemplate]=“template”></calendar>
  

• weekviewAllDayEventTemplate
  Type: TemplateRef<IDisplayAllDayEvent>
  The template provides customized view for all day event in the weekview

    <template #template let-displayEvent="displayEvent">
        <div class="calendar-event-inner">{{displayEvent.event.title}}</div>
    </template>
  
    <calendar ... [weekviewAllDayEventTemplate]=“template”></calendar>
  

• weekviewNormalEventTemplate
  Type: TemplateRef<IDisplayEvent>
  The template provides customized view for normal event in the weekview

    <template #template let-displayEvent="displayEvent">
        <div class="calendar-event-inner">{{displayEvent.event.title}}</div>
    </template>
  
    <calendar ... [weekviewNormalEventTemplate]=“template”></calendar>
  

• dayviewAllDayEventTemplate
  Type: TemplateRef<IDisplayAllDayEvent>
  The template provides customized view for all day event in the dayview

    <template #template let-displayEvent="displayEvent">
        <div class="calendar-event-inner">{{displayEvent.event.title}}</div>
    </template>
  
    <calendar ... [dayviewAllDayEventTemplate]=“template”></calendar>
  

• dayviewNormalEventTemplate
  Type: TemplateRef<IDisplayEvent>

    <calendar ... [dayviewNormalEventTemplate]=“template”></calendar>
  

EventSource

EventSource is an array of event object which contains at least below fields:

• title

• startTime
  If allDay is set to true, the startTime has to be as a UTC date which time is set to 0:00 AM, because in an allDay event, only the date is considered, the exact time or timezone doesn't matter.
  For example, if an allDay event starting from 2014-05-09, then startTime is

    var startTime = new Date(Date.UTC(2014, 4, 8));
  

• endTime
  If allDay is set to true, the startTime has to be as a UTC date which time is set to 0:00 AM, because in an allDay event, only the date is considered, the exact time or timezone doesn't matter.
  For example, if an allDay event ending to 2014-05-10, then endTime is

    var endTime = new Date(Date.UTC(2014, 4, 9));
  

• allDay
  Indicates the event is allDay event or regular event

Known issue

This component updates the ion-slide dynamically so that only 3 looped slides are needed.
The ion-slide in Ionic2 uses Swiper. It seems in the Swiper implementation, the next slide after the end of looped slide is a separate cached slide, instead of the first slide.
I can't find out a way to force refresh that cached slide, so you will notice that when sliding from the third month to the forth month, the preview month is not the forth month, but the first month.
Once the sliding is over, the slide will be forced to render the forth month.
