Typically beginning in May and ending in late June. These cicadas will begin to emerge approximately when the soil 8" beneath the ground reaches 64 degrees Fahrenheit. A nice, warm rain will often trigger an emergence. Back in 2004, people began reporting emergences around May, 13th, but if the weather is warmer, it might start in late April. Update: in 2021, they started in Tennessee on 4/27.
Other tips: these cicadas will emerge after the trees have grown leaves, and, by my own observation, around the same time Iris flowers bloom:

This is an example of a typical cicada emergence. The exact dates will depend on the weather and density of the emergence in your location. Hot weather means an early start and quicker finish to the season — cool weather means a later start, and a protracted season.
If you’re planting trees, wait until July. If your yard doesn’t get cicadas by the first week of June, it’s probably safe to plant in June. It’s the egg-laying that does damage. Talk to an arborist or tree expert if you’re actually concerned. I can’t answer your questions.
