• Range Constraints: Min/max time with strict validation and boundary enforcement
• Comprehensive Event System: change, focus, blur, open, close, created, destroyed, cleared, itemRender events
• Masked Input Support: Optional masked input format for guided user entry
• Persistence & RTL: State persistence across reloads and right-to-left language support
• Advanced Features: Strict mode validation, floating labels, keyboard customization, timezone support
• Accessibility: Full WCAG 2.2 compliance, keyboard navigation, WAI-ARIA support
• Theme Support: Material, Bootstrap, Tailwind, Fabric with light/dark variants
• Mobile Optimized: Full screen mode on mobile devices, touch-friendly interface

Quick Start Example

// app.component.ts
import { Component } from '@angular/core';
import { ChangeEventArgs } from '@syncfusion/ej2-calendars';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  // Simple time value
  timeValue: Date = new Date();
  
  // Configuration
  minTime: Date = new Date(2026, 2, 24, 8, 0);   // 8:00 AM
  maxTime: Date = new Date(2026, 2, 24, 20, 0);  // 8:00 PM
  format: string = 'hh:mm a';
  step: number = 30;  // 30-minute intervals
  
  // Event handler
  onTimeChange(args: ChangeEventArgs): void {
    console.log('Selected Time:', args.value);
    console.log('Selected Text:', args.text);
    console.log('Is User Interaction:', args.isInteracted);
  }
  
  onPopupOpen(): void {
    console.log('Time popup opened');
  }
  
  onPopupClose(): void {
    console.log('Time popup closed');
  }
}

<!-- app.component.html -->
<div style="padding: 20px;">
  <h2>Select a Time</h2>
  
  <ejs-timepicker
    id="timepicker"
    [value]="timeValue"
    [format]="format"
    [min]="minTime"
    [max]="maxTime"
    [step]="step"
    placeholder="Select time"
    (change)="onTimeChange($event)"
    (open)="onPopupOpen()"
    (close)="onPopupClose()">
  </ejs-timepicker>
  
  <p *ngIf="timeValue">
    Selected Time: {{ timeValue | date:'shortTime' }}
  </p>
</div>

Common Patterns

Pattern 1: Business Hours Time Selection

export class AppComponent {
  minTime: Date = new Date(2026, 2, 24, 9, 0);   // 9:00 AM
  maxTime: Date = new Date(2026, 2, 24, 18, 0);  // 6:00 PM
  timeValue: Date = new Date(2026, 2, 24, 10, 0);
  format: string = 'hh:mm a';
  step: number = 15;  // 15-minute intervals
}

<ejs-timepicker
  [value]="timeValue"
  [min]="minTime"
  [max]="maxTime"
  [step]="step"
  [format]="format"
  placeholder="Select appointment time">
</ejs-timepicker>

Pattern 2: 24-Hour Format

export class AppComponent {
  timeValue: Date = new Date();
  format: string = 'HH:mm';  // 24-hour format
  step: number = 30;
}

<ejs-timepicker
  [value]="timeValue"
  [format]="format"
  [step]="step"
  placeholder="Select time (24-hour)">
</ejs-timepicker>

Pattern 3: Masked Input for Guided Entry

export class AppComponent {
  timeValue: Date;
  enableMask: boolean = true;
  maskPlaceholder = {
    hour: 'hh',
    minute: 'mm',
    second: 'ss'
  };
  format: string = 'hh:mm:ss a';
}

<ejs-timepicker
  [value]="timeValue"
  [enableMask]="enableMask"
  [maskPlaceholder]="maskPlaceholder"
  format="hh:mm:ss a">
</ejs-timepicker>

Pattern 4: Reactive Forms Integration

import { FormBuilder, FormGroup, Validators } from '@angular/forms';

export class AppComponent {
  appointmentForm: FormGroup;
  
  constructor(private fb: FormBuilder) {
    this.appointmentForm = this.fb.group({
      appointmentTime: [
        new Date(),
        [Validators.required]
      ]
    });
  }
  
  submitForm(): void {
    if (this.appointmentForm.valid) {
      console.log(this.appointmentForm.value);
    }
  }
}

<form [formGroup]="appointmentForm">
  <ejs-timepicker
    formControlName="appointmentTime"
    format="hh:mm a"
    placeholder="Select time">
  </ejs-timepicker>
  
  <button (click)="submitForm()" [disabled]="!appointmentForm.valid">
    Submit
  </button>
</form>

Pattern 5: Time Range Selection

export class AppComponent {
  startTime: Date = new Date();
  endTime: Date = new Date(Date.now() + 3600000);  // +1 hour
  
  onStartTimeChange(args: ChangeEventArgs): void {
    // Ensure end time is after start time
    if (args.value && this.endTime <= args.value) {
      this.endTime = new Date(args.value.getTime() + 3600000);  // +1 hour
    }
  }
}

<div>
  <label>Start Time:</label>
  <ejs-timepicker
    [value]="startTime"
    format="hh:mm a"
    (change)="onStartTimeChange($event)">
  </ejs-timepicker>
  
  <label>End Time:</label>
  <ejs-timepicker
    [value]="endTime"
    [min]="startTime"
    format="hh:mm a">
  </ejs-timepicker>
</div>
