Zavod Time
Sixty seconds to the minute. Sixty minutes to the hour. Twenty-four hours to the day. Not one of those three numbers has a reason to be what it is beyond habit. Here the base is one hundred throughout — and the day has been recalibrated to fit it exactly, with nothing left over.

Calendar
Thirteen months, one and the same layout
The year is made of 13 months of 28 days each — four full weeks, not one day over. The first of the month is always a Monday. The 8th, the 15th and the 22nd are therefore always Mondays too, in every month, every year. The 13th falls on a Saturday. Always. Friday the 13th does not occur; it was removed by arithmetic, not by superstition.
The one or two days left over — Year Day, at the very end of the year, and in leap years Leap Day, in the middle of it — belong to no month and to no week. They stand outside the count on purpose, so that the rest of the system stays clean. They are not gaps in the schedule. They are room to breathe.

Results of conducted research
The Authority compared the zavod system against the arrangement already in place and established the following beneficial effects:
- Noon falls exactly at the start of the fifth zavod hour — half the day, no remainder, and no argument over whether the count begins at zero or at twelve.
- The week stays the week. Seven days, untouched: only what was already arbitrary has been changed.
- The monthly layout never has to be redrawn. One grid holds for all thirteen months, every year.
- The zavod hour reads off directly as one tenth of the day, exactly. When the third one strikes, the day is past thirty percent and short of forty — with nothing to convert.
- The zavod minute lasts the same everywhere: in Belgrade, in Novi Sad, in Promaja. Unlike the hour, nobody has ever moved it back or forward for the season.
Historical record
This is not the first application
The French Republic introduced decimal time in 1793 — a day of 10 hours, an hour of 100 minutes, a minute of 100 seconds. The Institute uses the same proportions, unchanged: if something counted correctly two hundred and thirty years ago, there is no reason it should not count correctly now. The system did not survive two full years. It did not fall because the arithmetic failed; it fell because every clock in the country would have had to be built over from scratch, and the Republic had more pressing business that year. The Institute does not read this as a warning but as proof: the idea outlived the arithmetic. It fell to logistics.
Kodak ran its business on a 13-month calendar from 1928 to 1989 — sixty-one full years. It did not abandon the system because the system stopped working. It abandoned it because the rest of the world around it never converted to the same reckoning, so the company was eventually obliged to fall back in line with everyone else, and not the other way round. The Institute takes this as confirmation: a system that ran correctly for sixty-one years is not an experiment. It is precedent.
