Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A common way of figuring out when it's the best time to plant corn is to examine the USDA zone info for Lebanon.

The last month that you can plant corn and expect a good harvest is probably August. If you wait any later than that and your corn may not have a chance to fully mature. If you are starting your corn indoors then you might be able to get away with starting them a few weeks earlier.
