It's a function of timing. January through April is "Youth League" season in Utah, with 4 "Youth Cups", 4 "High School Cups", and team relay events dominating the calendar. Adding to schedule overload is the fact that no organizer dares schedule a Sunday tournament in Utah.
Because youth fencing dominates the winter months, Utah organizers have gone out of their way to host senior and open events earlier in the season. Check ASKFRED results for October 7, 14, 21, 27, November 4, 18, December 1, 9, 16, and January 1 and you'll see what I mean.
Not that that solves your problem
You'll see more opens on the calendar in May and June.
