Plot Description:

This plot displays some metrics about the start date and duration of the spring or fall season. The definition of the season being the period between the coldest 91 day stretch and subsequent warmest 91 day stretch. 91 days being approximately 1/4 of the year, assuming the four seasons are to be equal duration. Of course, this is arbitrary, but interesting to look at!
