Check date

Use this action to check whether a specific date is a workday, based on the workdays and holidays you configured for your Workday sensor.

This action returns its result in a response variable, which you can use in later steps of the same automation or script.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To check a date from an automation or a script:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation or script, or select Create automation > Create new automation.
  3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
  4. In the Then do section, select Add action.
  5. Select what you want to control. Under By target (see Targets), select your Workday sensor.
  6. From the actions shown for that target, select Check date.
  7. Set the Date you want to check.
  8. Select Save.

Options in the UI

Date (Required)

The date to check, such as 2023-12-25.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as workday.check_date. Store the result in a response variable so you can use it in later steps:

ActionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called *sequence*. [Learn more]
action: workday.check_date
target:
  entity_id: binary_sensor.workday
data:
  check_date: "2023-12-25"
response_variable: check_date

This checks whether 2023-12-25 is a workday for binary_sensor.workday.

Options in YAML

check_date string Required

The date to check, such as 2023-12-25.

Targets of the action

This action requires a target. The target is the object of the action. You can point the action at a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label, and Home Assistant will run the action on every matching binary_sensor entity behind that target.

  • Entity: one specific binary_sensor entity, such as binary_sensor.living_room.
  • Device: every binary_sensor entity that belongs to a device.
  • Area: every binary_sensor entity in a room or area.
  • Floor: every binary_sensor entity on a floor.
  • Label: every binary_sensor entity that shares a label.

You can also select different target types in one action. For example, you can add a specific entity and an area as targets in the same action to run the action on both of them at once.

Response data

The action returns a workday field that is true when the date is a workday and false when it is not.

A shortened example of the response looks like this:

binary_sensor.workday:
  workday: true
