The United Nations Volunteers (UNV) programme's slogan for this IVD – Together, Act Now – highlights the value of volunteers and their ability to create positive change. Events to mark the day are held in every region of the world, bringing together volunteers, governments, and civil society to celebrate the spirit of volunteering. This IVD, UNV encourages all our partners to join us in our campaign, with the associated hashtag #TogetherActNow.
