Turn on Light Only if I'm Not on Holiday

I have the following simple automation to turn on my office light whilst I’m at work (in my home office) once the sun sets, but I’d like to add a condition that it only turns on the light if there’s no all day calendar entry containing the word “holiday”.

I’ve had a look at Calendar Triggers but I think this would probably need to be a condition (along the lines of if title does not contain "holiday") but I’ve not been able to figure out how to go about setting that condition up.

I’m not too sure how to do this or if it’s possible, so I’m wondering if anybody has some suggestions?

alias: Turn on Office Big Light
description: ""
  - platform: sun
    event: sunset
    offset: "-00:10:00"
  - condition: time
    after: "09:00:00"
    before: "17:30:00"
      - mon
      - tue
      - wed
      - thu
      - fri
  - service: light.turn_on
    metadata: {}
    data: {}
      entity_id: light.office_big_light
mode: single

Another angle would be to try the workday integration

The workday sensor is what I use. You can set it for and days that you are going on Holiday very easily.

Fantastic, thanks for that @steriku and @rujelus22 will give that a go.
