To show support, Hollywood’s finest, as well as dignitaries and social advocates are helping spread the word to support the brave efforts of humanitarians by participating in the #CallforCode global social campaign, which helps people prepare for and recover from natural disasters.

Recognized as an official U.N. observance supported by the 193 member states of the United Nations, Aug. 19 is devoted to the humanitarian personnel who come to the aid of people in need. As of now, the combined social voice is over 610 million strong and growing.

So be on the lookout on Aug. 19 for more on #CallforCode and ways that you can support World Humanitarian Day.
