Caveat on the Planting Calendar feature: pay attention to where the location tied to your zip code is getting their data from. When I plug in my zip code, the closest data station is about 15 minutes north of me, which would appear to be a good fit, BUT is a much more protected agricultural river valley and further inland than my particular location. I have better luck entering a zip code that is 30 minutes south of me but about the same distance from open water and hence closer in micro-climate to my own. There is about a 2 week difference between the two, with the northern river valley able to plant earlier. Once you figure what the best fit is for your specific location, the Planting Calendar works great.
