NPRMs and similar documents requesting comments usually give due date relative to Federal Register publication date - obviously not known immediately. But when it is known there is now no way to find the date on the FCC site, one must search in the FR and then do your own math.

Here is a page OET used to maintain showing dockets, a short description that is understandable, and the actual due date.

Something similar should be done on a commission-wide basis. This will facilitate participation by those without K Street lawyers.
