Good evening Julien and welcome to the Events Calendar forum!
Thank you for your interest in our products.
We’ll be glad to answer your questions.
I would like to know if it is possible to try the Pro version few days before buying it to be sure it will correspond to my needs?
Unfortunately, we do not offer trial versions.
That said, we do have the next best thing. We have a 30 days refund policy, no questions asked.
That should allow you to try things out to your liking.
Also, please reach out if you have questions while experimenting.
Best regards,
Geoff B.
