The National Day of Prayer will be Thursday, May 3, 2018. It has been held around annually in the spring since 1952. But you will never see it in the MSM; oh, no.
The web site linked above has resources, literature, downloadables, etc.
It is wonderful to be with so many other believers on the National Mall; but it isn't necessary. Individuals or churches and synagogues can organize their own observance. Last year I couldn't make it to DC, but a friend organized one in a pavilion of a public park in a small town, and it was well attended.
Get started today finding your place and handing out flyers.
