Holding your mouse on a site, you will get you a pop-up with name, location & GDD info.  This GDD is calculated from the average month temperature during the past 20 years ( from ). Now the info from here is limited to a 12 months temperature index, meaning that I could miss up to ½ a month GDD in spring and ½ a month in the other end of the warm GDD season. So you probably have to add 100-200 GDD in worst case.
