Thanks, @Jason_Woods, and hi, @anon65533956,
Depending on the format of the output you’re looking for, you might find a solution with Asana2Go (more info at Asana2Go: Copy, export, and print from Asana flexibly (Free for most users/companies)). There are 20 or so standard formats to try out, and you can create any custom format you desire with Asana2Go too.
But if you’re looking for a pure calendar format, I like @Stephanie_Oberg’s solution with a saved Advanced Search report saved in Calendar view.
