have a religious issue ( day of events )

Hi CB, I'm a Personal trainer and I have a female client who is a 7th day adventist, they follow the Jewish calender and as such Fridays at sundown to 24hrs later is Sabbath. She wants to do the novice IDFA transformation in Miss. this year and fortunately that falls on a Sunday it looks like. But I have not been able to find information or dates on other contests that might occur on a Sunday for novice figure.

ANY help would be appreciated. thank you
