Time Picker

Time Picker is an input field for entering or selecting a specific time.

Open in a
new tab
<vaadin-time-picker label="Alarm" value="07:00"></vaadin-time-picker>

The time can be entered directly using a keyboard or by choosing a value from a set of predefined options presented in an overlay. The overlay opens when the field is clicked or any input is entered when the field is focused.

Common Input Field Features

Time Picker includes all Text Field and shared input field features.

Step

Time Picker’s step parameter defines the interval (in seconds) between the items displayed in the overlay. It also specifies the amount by which the time increases/decreases using the Up/Down arrow keys (when the overlay is disabled).

The default step is one hour (that is, 3600). Unlike Number Field, Time Picker accepts values that don’t align with the specified step.

Open in a
new tab
<vaadin-time-picker
  label="Meeting time"
  value="12:30"
  .step="${60 * 30}"
></vaadin-time-picker>
Note
Use common steps
The step must divide an hour or day evenly. For example, "15 minutes", "30 minutes" and "2 hours" are valid steps, whereas "42 minutes" isn’t.

The displayed time format changes based on the step.

Open in a
new tab
<vaadin-time-picker label="Message received" value="15:45:08" step="1"></vaadin-time-picker>

Step Format

Less than 60 seconds

HH:MM:SS

Less than 1 second

HH:MM:SS:FFF

Note
Limit the number of steps
The overlay doesn’t appear for steps less than 900 seconds (15 minutes), to avoid showing an impractical number of choices.

Auto Open

The overlay opens automatically when the field is focused using a pointer (mouse or touch), or when the user types in the field. You can disable this, to open the overlay only when the toggle button or Up/Down arrow keys are pressed.

Open in a
new tab
<vaadin-time-picker
  label="Alarm"
  value="05:30"
  .step="${60 * 30}"
  auto-open-disabled
></vaadin-time-picker>

Validation

Minimum and Maximum Value

You can define a minimum and maximum value for Time Picker if you need to restrict the input to a specific range:

Open in a
new tab
<vaadin-time-picker
  label="Appointment time"
  helper-text="Open 8:00-16:00"
  value="08:30"
  min="08:00"
  max="16:00"
  .step="${60 * 30}"
></vaadin-time-picker>

Custom Validation

If the minimum and maximum values aren’t sufficient for validation, you can also apply custom validation.

Open in a
new tab
private binder = new Binder(this, AppointmentModel);

firstUpdated() {
  this.binder.for(this.binder.model.startTime).addValidator({
    message: 'The selected time is not available',
    validate: (startTime: string) => {
      return (
        (startTime >= '08:00' && startTime <= '12:00') ||
        (startTime >= '13:00' && startTime <= '16:00')
      );
    },
  });
}

render() {
  return html`
    <vaadin-time-picker
      label="Appointment time"
      helper-text="Open 8:00-12:00, 13:00-16:00"
      min="08:00"
      max="16:00"
      .step="${60 * 30}"
      ...="${field(this.binder.model.startTime)}"
    ></vaadin-time-picker>
  `;
}

Best Practices

Use Time Picker when the user needs to choose a time of day. Don’t use it for durations, such as for a stopwatch or timer.
