Calendar Description
The Julian Annunciation calendar is a variant of the Julian calendar obtained by shifting the year change back from the 1st January to the 25th March. It is also known as the calculus pisanus since this method was used in Pisa.
Use Case
Although it may appear more logical (considering that it followed the Nativity calendar), the calculus pisanus version of the Julian Annunciation calendar was much less common than the calculus florentinus one.
- Northern Italy from around the 11th century, including Pisa where it was used until 1750.
