Arduino Perpetual Calendar Clock
This video shows an Arduino Perpetual Calendar Clock automatically stepping from the 28th February to 1st March.
The clock uses 2 electro mechanical clock movements controlled by an Arduino to display the Day and Month. A third quartz controlled movement displays the time tide Low or High tide.
The Calendar is fully automatic and takes into account leap years as well as summer and winter time changes.
