Treat it with a very large pinch of salt!

If I were to believe its idea that my last frost is in early May, I'd
lose an awful lot of plants.

Yes, indeed. And, since nobody has mentioned it, the date is likely
to vary by plus or minus a month, occasionally more. In 25 years
in Cambridge, the first I have seen was September 6th and the last
was late December.
