Hi Fabrice Boyer,
Thank you for your contribution! 

I've reviewed OSM and noticed that the following element with a different name already exists: 
"Farm Show (10.00am 1.00pm 3.30pm)" (tourism=attraction)
https://osm.org/node/11896160769

Could you please confirm if this matches the details in your note?
