* A face for telling the dates and times of solstices and equinoxes
*
* It shows the upcoming solstice or equinox by default. The upper right number
* is the year, and the bottom numbers are the date in MMDD format. Use the
* alarm / light buttons to go forwards / backwards in time. Long press the
* alarm button to show the time of the event, including what weekday it is on,
* in your local timezone (DST is not handled).
*
* Supports the years 2020 - 2083. The calculations are reasonably accurate for
* years between 1000 and 3000, but limitations in the sensor watch libraries
* (which could easily be worked around) prevent making use of that.
