Complementary Days in The French Republican Calendar Alarm Clock

This is an optional bonus part of the lab, and should be attempted after finishing the non-optional part of the French Republican Calendar.

After finishing the base French Republican Calendar Alarm Clock (and more importantly, restocking the Advil), you decide to take a stab at handling complementary days. To remind yourself what complementary days are, you check your notes and read that at the end of every year, there are 5 extra days (6 extra days in leap years) that were designated as national holidays at the end of every year. You find that years that are year mod 4 = 3 are leap years. You decide that since you have the space, you can define a 13th “month” that holds these complementary days.

This would mean that your alarm clock would behave similarly to the base clock for the first 12 months. But on the 13th month, the day counter rolls over at 5 (displays 0-4) on a regular year and will roll over at 6 (displays 0-5) on a leap year. Additionally, since there are only 5 or 6 days in this “month”, when the days reset the months need to reset as well (and increment the year).

Goals

1. Learn how to use Digital
2. Create a fully functional French Republican Calendar

Instructions

All of your work should be a continuation of FrenchRepublicanCalendarAlarmClock (it will save as FrenchRepublicanCalendarAlarmClock.dig).

Please use the logic outlined above to implement your updated calendar.

Remember, your final circuit should implement:

• The correct time functionality (outlined in bold in the lore above)
• The CLR pin clears everything
• The time setting logic
• The alarm setting logic
• The alarm buzzing logic
• The display functionality
