We've continued to run data through the blender, and now have come up with information related to the last frost of the spring and the first frost of the autumn. 

And from there, we can tell you how long your frost-free growing season is.

Since these dates are not exactly consistent, you'll notice there's some scientific slop in the estimates provided on your profile pages.

For the mathletes who are reading, we calculated the median dates (in terms of day-of-year) for the last 15 years, calculated the standard-deviation, and provided a range 2 deviations on either side of the median.

For the non-mathletes, that means roughly 95% of the time, the actual frost dates will fall within that range.  But there's still a chance that they may occur before/after the ranges provided.

That's mother nature for you.
