Submit your event
Are you organising a trade fair, a cup, a congress or a festival in the cannabis or hemp industry? Listing it on Calendar420 is free. Send us the basic details through this form and we'll add it to the guide with its own page, in nine languages.
How it works
We check every event against its official website before publishing, so the dates and location are right. If we're missing anything, we'll email you at the address you give us. No need to sign up.
