Calendar Description - Scheme jap
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.
Definition
The Record consists of three julian required Fields named year,
month and day, a calculated field cyear
and the optional field wday.
The field cyear is the Civil Year while the year is the Historic Year.
| Record - Default order | ||||
|---|---|---|---|---|
| year | month | day | cyear | wday |
| Record - Ranking order | ||||
|---|---|---|---|---|
| cyear | month | day | wday | year |
The field cyear (civil year) equals year (historic year)
apart from the days 25th March to 31st December, when cyear equals year + 1

Formats
Formatting a date for schemes where the New Year date (Historical Year) and Year number increment date (Civil Year) is different can lead to confusion if it is not made clear which year is displayed. It is proposed that the dual dating system is used for this scheme.
Dual Dates
The Civil year is always shown in full. If this is the same as the Historical year then this is the only year shown. If the years differ, then the last digit (or as many as are different) is shown. This is separated from the Civil year with a '/' slash character.
