A day the 29 countries in Europe and North America set aside to promote data privacy, to try and educate people, particularly teens and children.
Unfortunately this is the only thing I could really find for today but I do believe it is an important subject so don't feel bad about promoting it. We should be helping people who are younger or do not understand the way information and data can spread across the internet through social networks. It is a good idea to help teach those or even learn a thing or two ourselves.
