One of the first steps you take when you are figuring out your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A way of determining when to plant tagetes is to look at the USDA zone info for Troy.

The last month that you can plant tagetes and expect a good harvest is probably August. You probably don't want to wait any later than that or else your tagetes may not have a chance to grow to maturity. If you are starting your tagetes indoors then you might be able to get away with starting them a couple of weeks earlier.
