In Angular, how to dynamically set min date and max date in date picker?

In Angular, you can dynamically set the minimum and maximum dates in a date picker by binding the min and max attributes to properties in your component. This approach works with both native HTML5 date inputs and various Angular UI libraries that offer date pickers, such as Angular Material, ng-bootstrap, or ngx-bootstrap.

Here's a basic example using the native HTML5 date input:

HTML Template:

<input type="date" [min]="minDate" [max]="maxDate">

Angular Component:

import { Component } from '@angular/core'; @Component({ selector: 'app-date-picker', templateUrl: './date-picker.component.html' }) export class DatePickerComponent { minDate: string; maxDate: string; constructor() { // Set the min and max dates let today = new Date(); this.minDate = this.formatDate(today); // Set max date to 7 days from today let maxDate = new Date(); maxDate.setDate(maxDate.getDate() + 7); this.maxDate = this.formatDate(maxDate); } private formatDate(date: Date): string { // Format date to 'yyyy-MM-dd' let d = new Date(date), month = '' + (d.getMonth() + 1), day = '' + d.getDate(), year = d.getFullYear(); if (month.length < 2) month = '0' + month; if (day.length < 2) day = '0' + day; return [year, month, day].join('-'); } }

In this example:

  • The minDate and maxDate are properties of the component class, set to strings formatted as yyyy-MM-dd, which is the format required for the min and max attributes of the <input type="date">.
  • The formatDate method formats a JavaScript Date object into a string in the yyyy-MM-dd format.
  • The minDate is set to today's date, and maxDate is set to 7 days from today. You can adjust these as needed.

Angular Material Datepicker Example:

If you're using Angular Material, you can bind the min and max properties in a similar way:

<mat-form-field> <input matInput [matDatepicker]="picker" [min]="minDate" [max]="maxDate"> <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle> <mat-datepicker #picker></mat-datepicker> </mat-form-field>

The Angular component code would remain the same as in the previous example.

Notes:

  • When using UI libraries like Angular Material, ensure you have installed the necessary packages and imported the relevant modules in your Angular module.
  • Always test date input behavior across different browsers, as support and behavior can vary, especially for the native HTML5 date picker.
  • Keep time zones in consideration when setting min and max dates, as JavaScript's Date object uses the user's local time zone.

  1. Set Min Max Date Dynamically in Angular Datepicker:

    <!-- HTML Template --> <input [min]="minDate" [max]="maxDate" matInput [matDatepicker]="picker"> <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle> <mat-datepicker #picker></mat-datepicker> 
    // TypeScript Component import { Component } from '@angular/core'; import { MatDatepickerInputEvent } from '@angular/material/datepicker'; @Component({ selector: 'app-example', templateUrl: './example.component.html', styleUrls: ['./example.component.css'] }) export class ExampleComponent { minDate: Date = new Date(); maxDate: Date = new Date(); onDateChange(event: MatDatepickerInputEvent<Date>): void { this.minDate = event.value || new Date(); this.maxDate = new Date(this.minDate.getFullYear() + 1, this.minDate.getMonth(), this.minDate.getDate()); } }
    • Description: Use Angular Material datepicker and dynamically set the min and max date based on user selection.

  2. Dynamically Change Datepicker Range in Angular:

    <!-- HTML Template --> <input [min]="minDate" [max]="maxDate" [(ngModel)]="selectedDate" placeholder="Select a date" /> 
    // TypeScript Component import { Component } from '@angular/core'; @Component({ selector: 'app-example', templateUrl: './example.component.html', styleUrls: ['./example.component.css'] }) export class ExampleComponent { minDate: Date = new Date(); maxDate: Date = new Date(); selectedDate: Date = new Date(); constructor() { this.maxDate.setDate(this.minDate.getDate() + 30); // Set max date to 30 days from today } }
    • Description: Use two-way data binding with ngModel to dynamically change the datepicker range.

  3. Angular Datepicker Dynamic minDate and maxDate:

    <!-- HTML Template --> <input [min]="minDate" [max]="maxDate" matInput [matDatepicker]="picker" [(ngModel)]="selectedDate"> <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle> <mat-datepicker #picker></mat-datepicker> 
    // TypeScript Component import { Component } from '@angular/core'; @Component({ selector: 'app-example', templateUrl: './example.component.html', styleUrls: ['./example.component.css'] }) export class ExampleComponent { minDate: Date = new Date(); maxDate: Date = new Date(); selectedDate: Date = new Date(); constructor() { this.maxDate.setDate(this.minDate.getDate() + 30); // Set max date to 30 days from today } }
    • Description: Utilize Angular Material datepicker with dynamic minDate and maxDate.

  4. Update Datepicker Min and Max Date Programmatically:

    <!-- HTML Template --> <input [min]="minDate" [max]="maxDate" [(ngModel)]="selectedDate" placeholder="Select a date" /> 
    // TypeScript Component import { Component } from '@angular/core'; @Component({ selector: 'app-example', templateUrl: './example.component.html', styleUrls: ['./example.component.css'] }) export class ExampleComponent { minDate: Date = new Date(); maxDate: Date = new Date(); selectedDate: Date = new Date(); constructor() { this.maxDate.setDate(this.minDate.getDate() + 30); // Set max date to 30 days from today } }
    • Description: Programmatically update the min and max date of the datepicker based on business logic.

  5. Change mat-datepicker Min and Max Date Angular:

    <!-- HTML Template --> <input [min]="minDate" [max]="maxDate" matInput [matDatepicker]="picker" [(ngModel)]="selectedDate"> <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle> <mat-datepicker #picker></mat-datepicker> 
    // TypeScript Component import { Component } from '@angular/core'; @Component({ selector: 'app-example', templateUrl: './example.component.html', styleUrls: ['./example.component.css'] }) export class ExampleComponent { minDate: Date = new Date(); maxDate: Date = new Date(); selectedDate: Date = new Date(); constructor() { this.maxDate.setDate(this.minDate.getDate() + 30); // Set max date to 30 days from today } }
    • Description: Change the min and max date of the Angular Material datepicker dynamically.

  6. Angular Dynamic Date Range in Datepicker:

    <!-- HTML Template --> <input [min]="minDate" [max]="maxDate" matInput [matDatepicker]="picker" [(ngModel)]="selectedDate"> <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle> <mat-datepicker #picker></mat-datepicker> 
    // TypeScript Component import { Component } from '@angular/core'; @Component({ selector: 'app-example', templateUrl: './example.component.html', styleUrls: ['./example.component.css'] }) export class ExampleComponent { minDate: Date = new Date(); maxDate: Date = new Date(); selectedDate: Date = new Date(); constructor() { this.maxDate.setDate(this.minDate.getDate() + 30); // Set max date to 30 days from today } }
    • Description: Implement a dynamic date range in the Angular Material datepicker.

  7. Dynamically Set ng-bootstrap Datepicker Min Max Date:

    <!-- HTML Template --> <input [(ngModel)]="selectedDate" [ngbDatepicker]="dp" #d="ngbDatepicker" /> <button (click)="open(d)">Open</button> 
    // TypeScript Component import { Component } from '@angular/core'; import { NgbDateStruct, NgbCalendar } from '@ng-bootstrap/ng-bootstrap'; @Component({ selector: 'app-example', templateUrl: './example.component.html', styleUrls: ['./example.component.css'] }) export class ExampleComponent { minDate: NgbDateStruct; maxDate: NgbDateStruct; selectedDate: NgbDateStruct; constructor(private calendar: NgbCalendar) { this.minDate = this.calendar.getToday(); this.maxDate = this.calendar.getNext(this.calendar.getToday(), 'd', 30); // Set max date to 30 days from today } open(d: any): void { d.toggle(); } }
    • Description: Dynamically set the min and max date of the ng-bootstrap datepicker.

  8. Angular Reactive Form Datepicker Dynamic Range:
