Last Friday of a specific month automation

Configuration
1

I’m looking to create an automation that disables other automations basically 1x per year. I want to have an automation that runs on the “Last Friday of October”. How can I make that happen?

At what time of the day (on the last Friday of the month) do you want the automation to run?

The following example assumes you want it to run at 08:00:00. Change it to whatever you require.

alias: example
trigger:
  - platform: time
    at: '08:00:00'
condition:
  - condition: template
    value_template: >
      {{ now().isoweekday() == 5 and now().month == 10 and 
        now().month != (now() + timedelta(days=7)).month }}
action:
  ... your actions go here ...

How the template works

This confirms today is Friday:

now().isoweekday() == 5

This confirms the current month is October:

now().month == 10

This confirms the current month is not the same as the month in 7 days (i.e. next Friday is in a different month).

now().month != (now() + timedelta(days=7)).month

If both tests are true then the current Friday is the last one in October.

Testing

Today is Friday October 27 and is the last Friday in October. Here’s the template confirming it’s the last Friday of the month.

EDIT

Correction. I overlooked your requirement that it must be the last Friday of a specific month, namely October (as opposed to the last Friday of any month). I have amended the template and it now also checks if the current month is the 10th month of the year (October).
