Marked on the first Saturday of May each year which people are encouraged to tend their gardens or some portion of it clothes free. From the WNGD web site
All that’s involved is getting naked and making the world’s gardens–whatever their size, public or private–healthier and more attractive. WNGD has no political agenda, nor is it owned or organized by any one particular group. Naked individuals and groups are encouraged to adopt the day for themselves.
Why garden naked? First of all, it’s fun! Second only to swimming, gardening is at the top of the list of family-friendly activities people are most ready to consider doing nude. Moreover, our culture needs to move toward a healthy sense of both body acceptance and our relation to the natural environment. Gardening naked is not only a simple joy, it reminds us–even if only for those few sunkissed minutes–that we can be honest with who we are as humans and as part of this planet.
