These are the stories within the official canon of the Vicendum story project. The ebooks posted here are the completed projects, and will be updated with new material regularly.

The Vicendum series uses a combined timekeeping method of real time and the floating timeline. Vicendum's history occurs within a defined past, but stories set in the present day use the floating timeline.

The current year- in-universe- is 343, which is analogous to our present day.

To denote the time each scene takes place within the story, a 24-hour clock is used and the date, month and year are marked by numbers with the prefix of "Date" (so July 12th of the current year is listed as "Date 7.12.343").

In-universe, the year is 343 is because in the area where most of the story takes place- the democratic bloc, led by the Crimson Rose Federation- the Gregorian Calendar was abandoned and democracies instead count the years with the first year of the Rose Revolution (1682) being Year 1.

That is the only real change with our form of timekeeping that the Rose Revolutionaries made. They have kept the 24-hour clock and the 12-month, 365-day year (divided as we would know them). Weeks are not defined, but are still informally observed.

The names, though of the months and of the days of the week are not formally in use. Informally, the names for the days of the week and the months are still in use, but usage of the latter is controversial. This is because the Revolutionaries decreed the old naming systems to be "symbols of authoritarianism" so they got rid of the names entirely. Since there is still a use for the names of the days of the week (since week lengths are still observed around the Federation), using the names does not rankle people, but since the months are clearly defined by numbers, the names of the month are seen as "not needed" so anyone that uses them are seen as rebels.

The timekeeping by the Crimson Roses follows other aspects of the Vicendum world, which, because of its divisions, has no universal standards for not just timekeeping but also of other units of measurement, such as weights, distances and currency. Telecommunication networks are also divided (to the extent possible), as are many other systems (such as copyrights) owing to the deep political divisions within the world.
