Calendar

A full-featured native calendar view for NativeScript with month, week, and year display modes, multiple selection modes, event markers, custom styling, and programmatic control.

The plugin celebrates two best-in-class native libraries:

iOS: HorizonCalendar by Airbnb
Android: kizitonwose Calendar

Installation

bash

npm install @nstudio/nativescript-calendar

Register the Component

typescript

import { registerElement } from '@nativescript/angular';
import { NCalendar } from '@nstudio/nativescript-calendar';

registerElement('NCalendar', () => NCalendar);

NativeScript Core does not require registration — use the XML namespace:

xml

<Page xmlns:cal="@nstudio/nativescript-calendar">
  ...
</Page>

Basic Usage

html

<NCalendar
  displayMode="month"
  selectionMode="single"
  orientation="vertical"
  interMonthSpacing="16"
  (daySelect)="onDaySelect($event)">
</NCalendar>

typescript

import { CalendarDayEventData } from '@nstudio/nativescript-calendar';

export class CalendarComponent {
  onDaySelect(args: CalendarDayEventData) {
    const day = args.data.day;
    console.log(`Selected: ${day.year}-${day.month}-${day.day}`);
  }
}

Display Modes

Month (default)

The standard month view with continuous vertical or horizontal scrolling.

html

<NCalendar displayMode="month"></NCalendar>

Week

A single-row week strip. Swipe left or right to navigate between weeks.

html

<NCalendar displayMode="week"></NCalendar>

Year

A grid of mini-month calendars. Control the number of columns with monthColumns.

html

<NCalendar displayMode="year" [monthColumns]="3"></NCalendar>

Selection Modes

Single (default)

Tap to select one date. Tap again to deselect.

Range

Tap a start date, then tap an end date. Dates in between are highlighted with a range band.

html

<NCalendar selectionMode="range" (daySelect)="onRangeSelect($event)"></NCalendar>

typescript

onRangeSelect(args: CalendarDayEventData) {
  const calendar = args.object as NCalendar;
  const range = calendar.selectedDateRange;
  if (range) {
    console.log(`${range.start} to ${range.end}`);
  }
}

Multiple

Tap to toggle individual dates on or off.

typescript

const selected = calendar.getSelectedDates();
console.log(`${selected.length} dates selected`);

None

Day taps are disabled. Useful for display-only calendars.

Orientation & Paging

Vertical Scroll (default)

Months flow top to bottom in a continuous scroll.

Horizontal Paged

One month at a time. Swipe left or right to navigate.

html

<NCalendar orientation="horizontal" [scrollPaged]="true"></NCalendar>

Events / Markers

Add colored dot markers to calendar days using the events property.

typescript

import { CalendarEvent } from '@nstudio/nativescript-calendar';

const events: CalendarEvent[] = [
  { date: new Date(2026, 2, 3), color: '#E91E63', data: { title: 'Team Standup', time: '9:00 AM' } },
  { date: new Date(2026, 2, 3), color: '#2196F3', data: { title: 'Design Review', time: '2:00 PM' } },
  { date: new Date(2026, 2, 7), color: '#4CAF50', data: { title: 'Lunch with Sarah', time: '12:30 PM' } },
];

html

<NCalendar [events]="events" (daySelect)="onEventDaySelect($event)"></NCalendar>

Each event produces a small colored dot below the day number. Multiple events on the same day show multiple dots. The data field is passed through for your use (e.g. to display event details on tap).

Disabled Dates

Prevent specific dates or entire weekdays from being selected. Disabled days are rendered with disabledDayTextColor and cannot be tapped.

Disable specific dates

typescript

// Disable holidays or other specific dates
calendar.disabledDates = [
  new Date(2026, 0, 1),   // New Year's Day
  new Date(2026, 11, 25), // Christmas
  new Date(2026, 6, 4),   // Independence Day
];

Disable weekdays

typescript

// Disable weekends (0 = Sunday, 6 = Saturday)
calendar.disabledWeekdays = [0, 6];

Combine both

html

<NCalendar
  [disabledDates]="holidays"
  [disabledWeekdays]="[0, 6]"
  disabledDayTextColor="#CCCCCC">
</NCalendar>

typescript

export class BookingComponent {
  holidays = [
    new Date(2026, 0, 1),
    new Date(2026, 11, 25),
  ];
}

Disabled dates are also reported as isDisabled: true in the dayRender event, allowing further customization.

Custom Styling

All style properties can be set via template attributes or programmatically.

html

<NCalendar
  dayTextColor="#212121"
  todayTextColor="#FF6B6B"
  todayBackgroundColor="#2D2D2D"
  selectedDayTextColor="#FFFFFF"
  selectedDayBackgroundColor="#FF6B6B"
  selectedRangeColor="#FF6B6B40"
  weekendTextColor="#666666"
  monthHeaderTextColor="#FF6B6B"
  dayOfWeekTextColor="#999999">
</NCalendar>

Programmatic Control

Scrolling

typescript

// Scroll to today
calendar.goToToday(true);

// Scroll to a specific month
calendar.scrollToMonth(2026, 6, true);

// Scroll to a specific date
calendar.scrollToDate(new Date(2026, 5, 15), true);

// Navigate month by month
calendar.goToNextMonth(true);
calendar.goToPreviousMonth(true);

Selection

typescript

// Select a date
calendar.selectDate(new Date(2026, 2, 15));

// Deselect a date
calendar.deselectDate(new Date(2026, 2, 15));

// Select a range
calendar.selectDateRange(new Date(2026, 2, 1), new Date(2026, 2, 14));

// Get current selection
const dates: Date[] = calendar.getSelectedDates();

// Clear all selections
calendar.clearSelection();

Refresh

Force a full rebuild of the calendar when needed:

typescript

calendar.refresh();

Platform Notes

iOS

Uses Airbnb's HorizonCalendar via CocoaPods
Vertical month view supports pinned day-of-week headers (pinDaysOfWeekToTop)
Week view is implemented as a constrained single-row CalendarView

Android

Uses kizitonwose Calendar via Gradle
Native CalendarView, WeekCalendarView, and YearCalendarView for each display mode
Range selection renders with Airbnb-style start/end circles and connecting band
Day-of-week header row is managed natively with proper locale support
Requires coreLibraryDesugaring for java.time APIs on older Android versions
