/*
* PLANETARY TIME face
*
* BACKGROUND
*
* Both the 24 hour day and the order of our weekdays have quite esoteric roots.
* The ancient Egyptians divided the day up into 12 hours of sunlight and 12 hours
* of night time. Obviously the length of these hours varied throughout the year.
*
* The Greeks assigned each hour a ruler of the planetary gods in the ancient
* "Chaldean" order from slowest (Chronos for Saturn) to fastest (Selene for Moon).
* Because 24 hours cannot be equally divided by seven, the planetary rulers carried
* over to the first hour of the next day, effectively ruling over the entire day
* and lending the whole day their name. The seven day week was born.
*
* PLANETARY TIME COMPLICATION
*
* The hour digits of this complication watch-face display the current planetary hour
* according to the given location and day of the year (First hour from 12am to 1am,
* the second hour from 1am to 2am, and so forth).
*
* Like with normal clocks the minutes and seconds help dividing the hour into smaller
* units. On this watch-face, all units naturally vary in length because the planetary
* hours are not fixed by duration but by the moments of sunrise and sunset which
* obviously vary throughout the year, especially in higher latitudes.
*
* On this watch-face the hours indicated as 12am to 12pm (00:00 - 12:00) are used for
* the planetary daytime hours between sunrise and sunset and hours indicated as 12pm
* to 12am (12:00 - 00:00) are used for the planetary night hours after sunset and before
* sunrise.
*
* The planetary ruler of the current hour and day is displayed at the top in Latin or
* Greek shorthand notation:
*
* Saturn (SA) / Chronos (CH) / ♄
* Jupiter (JU) / Zeus (ZE) / ♃
* Mars (MA) / Ares (AR) / ♂
* Sol (SO) / Helios (HE) / ☉
* Venus (VE) / Aphrodite (AF) / ♀
* Mercury (ME) / Hermes (HR) / ☿
* Luna (LU) / Selene (SE) / ☾
*
* The ALARM button toggles between displaying the ruler of the hour and the ruler of the day
*
* The LIGHT button toggles between Latin and Greek ruler shorthand notation
*
* (IMPORTANT: Make sure the watch's time, timezone and location are set correctly for this
* watch face to work properly!)
