Here's How Volunteers Across The Globe Are Celebrating #MandelaDay With Service

When Nelson Mandela died in December 2013, the United Nations didn't rush to designate a day of commemoration for the social justice champion and former 27-year South African political prisoner -- they already had one.

In 2010, the UN officially adopted Nelson Mandela International Day (or Mandela Day for short) on July 18, Mandela's birthday. The idea wasn't (and still isn't) to add another public holiday to the calendar or to take a day off from work, but to find opportunities to act as Mandela did through volunteering and service. The Mandela Day website encourages people worldwide to devote 67 minutes of time today to help others, no matter how small the action.

There are a number of ways you can do that, and the Mandela Day site has an entire section devoted to specifying how. One of the ways is to spread the word via social media, and that's exactly what users across platforms have been doing.

But it's easy to superimpose an inspiring Mandela quote across an impressive photo. It's harder to get out and make some changes. Those are the images and messages we've compiled below. For #MandelaDay, all it takes is 67 minutes.

The volunteer group 67 Blankets gathered in Johannesburg to help knit warm blankets for those who don't have access to them.

Instagram user stephy.meow helped install new windows at a local service center and paint a nursing home in Phokwane, South Africa.

The Bikers For Mandela Day initiative saw cyclists ride to South Africa's southern Cape to raise awareness of violence against women and children.

And the #Trek4Mandela crew summited Mount Kilimanjaro as a fundraiser for over 250,000 girls to remain in school and receive an education.

Remember, July 18 isn't over just yet. There's still time for your 67 minutes.
