Ionic4 Datepicker Component

Author - Digvijay

Ionic4 Datepicker Component is our first contribution to Ionic4 Open Source Community. In Ionic1 for
Datepicker there was a nice option provided by rajeshwar patlolla’s Ionic1 Datepicker. But while I searched for a similar option, I found that either they are not compatible with angular or their use case is not match up with what we required. So then we decided to build something our own, we have implemented it nicely in our project, then we thought to make it as a library and make it open source. Ionic4 Datepicker Component is still in development in terms of configuration options and functionality.

Currently here is how it looks like:-


How to Use it

Step1: Install

npm i @logisticinfotech/ionic4-datepicker moment

Step2: Import it in your module and in import array

import { Ionic4DatepickerModule } from

  imports: [
        path: '',
        component: HomePage
  declarations: [HomePage]

Step3: In your component declare your model variable and date picker options

myDate = 'YOUR_DATE'; (assign your selected date to this Object)
let disabledDates: Date[] = [
      new Date(1545911005644),     
      new Date(),     
      new Date(2018, 12, 12), // Months are 0-based, this is August, 10th.     
      new Date('Wednesday, December 26, 2018'), // Works with any valid Date formats like long format     
      new Date('12-14-2018'), // Short format
datePickerObj: any = {
  inputDate: new Date('2018-08-10'), // default new Date()
  fromDate: new Date('2016-12-08'), // default null

Step4: Then in your html simply use it as below
Use Ionic4-datepicker As a Directive (Preferred)

<ion-input readonly [(ngModel)]="mydate"

Use Ionic4-datepicker As a Component

<li-ionic4-datepicker [(ngModel)]="mydate"

Programatically way

Please follow as below to open Datepicker Modal and get date onDismiss. (standard ionic way ModalController

import { Component, OnInit } from '@angular/core';
import { ModalController } from '@ionic/angular';

import { Ionic4DatepickerModalComponent } from 'ionic4-datepicker';

  selector: 'app-datepicker-button',
  templateUrl: './',
  styleUrls: ['./'],
export class DatepickerManuallyPage implements OnInit {

  datePickerObj: any = {};

    public modalCtrl: ModalController
  ) { }

  ngOnInit() {
    this.datePickerObj = {
      dateFormat: 'YYYY-MM-DD'

  async openDatePicker() {
    const datePickerModal = await this.modalCtrl.create({
      component: Ionic4DatepickerModalComponent,
      cssClass: 'li-ionic4-datePicker',
      componentProps: { 
         'objConfig': this.datePickerObj, 
         'selectedDate': this.selectedDate 
    await datePickerModal.present();

      .then((data) => {
        this.selectedDate =;

Note: For model to open as above image please add below css in your projects global.scss

.li-ionic4-datePicker {
    .modal-wrapper {
        height: 470px;
        max-height: 100%;
        width: 312px;

Want to use different color schema? please put css as below example to affect only inside datepicker modal.
Basically you can override all ionic theme variables here and it will automatically apply accordingly.

.li-ionic4-datePicker {
  .modal-wrapper {
      height: 470px;
      max-height: 100%;
      width: 312px;
      --ion-color-primary: red; // This Variable used for the change of colour ion-datepicker only.
      --ion-color-primary-tint: rgb(214, 153, 153); // This Variable changes the tint colour of background when click button.
      ion-button {
          // --ion-color-primary: green; // This Variable used for the change colour of buttons only.
          // --ion-color-primary-tint: lightgreen; // This Variable changes the tint color of background when click buttons.
          // --border-radious: 0px; // This Variable changes the border radious of buttons.
          // button customization css write here...

Please post any issue you found in GitHub or in the comment box below. Also request feature if you like to see it in this library.
This is our first Ionic/Angular Library so please suggest any improvements in code base also.

Looking forward to get community feedbacks.

# Breaking change in version 1.0.8

Due to issue in date formate `dd-MM-yyyy`, we have used moment js to solve it. Now this need to be
changed to `DD-MM-YYYY`
We are moving away from angular DatePipe so now only moment js date formats are valid.

so people who are using `dd` will require change it to `DD`
