Andersen The Most Accurate Type of Calendar Possible Genève With Perpetuel Secular Calender

Considering the shift between solar and civilian years, a day had to be added once every four years, in order to realign nature and administrative facts. Since Roman Emperor Julius Cesar, we have leap years. Then came a new type of calendar during the 16th century – the Gregorian Calendar – that was even more precise than the previous one. However the actual rotation of the moon and earth still didn’t exactly match, and now one day had to be removed once every 100 years.
