Collection of addresses and papers related to the subject of the world calendar which comes up for attention in two important world conferences this year. The plan is presented, its various aspects discussed, the arguments of sundry groups opposing it met, and the progress outlined. The hope is expressed that the general public will discuss the details of the plan and express their approval to back those advocating it. The movement is much further advanced than one on the outside would be apt to know. A book for a very limited market, from the bookshop's angle.
