The Calvary Hour was a religious radio program based out of Ohio that was broadcast internationally.
[1] The Calvary Hour began in November, 1936, founded by the pastor of Sterling, Ohio’s Pleasant Hill Mennonite Church, William G. Detweiler[1] shortly after his ordination.
[9] For the final fourteen years, the program was recorded at Colors Audio in Akron, Ohio.
[10] Production of the program ended in 2007 upon Bill Detweiler's retirement; the last show was broadcast on December 30 of that year.
[1][10] The governing board felt that the audience would not transition to another speaker after the program had been in a single family for such a lengthy time period.
