The input_datetime component allows the user to define date and time values that can be controlled via the frontend and can be used within automations and templates.

To add three datetime inputs to your installation, one with both date and time, and one with date or time each, add the following lines to your configuration.yaml:

# Example configuration.yaml entry
input_datetime:
  both_date_and_time:
    name: Input with both date and time
    has_date: true
    has_time: true
  only_date:
    name: Input with only date
    has_date: true
    has_time: false
  only_time:
    name: Input with only time
    has_date: false
    has_time: true

{% configuration %} input_datetime: description: Alias for the datetime input. Multiple entries are allowed. required: true type: map keys: name: description: Friendly name of the datetime input. required: false type: String has_time: description: Set to true if the input should have a time. At least one has_time or has_date must be defined. required: false type: boolean default: false has_date: description: Set to true if the input should have a date. At least one has_time or has_date must be defined. required: false type: boolean default: false initial: description: Set the initial value of this input, depending on has_time and has_date. required: false type: datetime | time | date default: 1970-01-01 00:00 | 1970-01-01 | 00:00 {% endconfiguration %}

{% linkable_title Attributes %}

A datetime input entity's state exports several attributes that can be useful in automations and templates.

Attribute	Description
has_time	true if this entity has a time.
has_date	true if this entity has a date.
year month day	The year, month and day of the date. (only available if has_date: true)
hour minute second	The hour, minute and second of the time. (only available if has_time: true)
timestamp	A timestamp representing the time held in the input. If has_date: true, this is the UNIX timestamp of the date / time held by the input. Otherwise if only has_time: true, this is the number of seconds since midnight representing the time held by the input.

{% linkable_title Restore State %}

This component will automatically restore the state it had prior to Home Assistant stopping as long as your entity does not have a set value for initial. To disable this feature, set a valid value for initial.

{% linkable_title Services %}

This component provides a service to modify the state of the input_datetime.

Service	Data	Description
set_datetime	time	This can be used to dynamically set the time.
set_datetime	date	This can be used to dynamically set the date.

{% linkable_title Automation Examples %}

The following example shows the usage of the input_datetime as a trigger in an automation (note that you will need a time sensor elsewhere in your configuration):

{% raw %}

# Example configuration.yaml entry
# Turns on bedroom light at the time specified.
automation:
  trigger:
    platform: template
    value_template: "{{ states('sensor.time') == (states.input_datetime.bedroom_alarm_clock_time.attributes.timestamp | int | timestamp_custom('%H:%M', False)) }}"
  action:
    service: light.turn_on
    entity_id: light.bedroom

{% endraw %}

To dynamically set the input_datetime you can call input_datetime.set_datetime. The following example can be used in an automation rule:

# Example configuration.yaml entry
# Sets input_datetime to '05:30' when an input_boolean is turned on.
automation:
  trigger:
    platform: state
    entity_id: input_boolean.example
    to: 'on'
  action:
    service: input_datetime.set_datetime
    entity_id: input_datetime.bedroom_alarm_clock_time
    data:
      time: '05:30:00'
