No plugin exists specifically for this, but there’s a value transformer called home-logo-image-url that could be used for this case I think. So maybe you can build a small theme component that:
- Uploads your seasonal logos as theme assets
- Uses
api.registerValueTransformer("home-logo-image-url", ...)to return the seasonal logo URL when today’s date falls within your configured window, and the default logo otherwise
It would make a useful addition to the theme component ecosystem!
