The time that unites us
Time is the only wealth that we all share equally. It crosses cultures, languages, and generations. It does not divide humanity — it connects us.
And yet even today, managing our time remains unnecessarily complicated, a model inherited from another era.
For more than four centuries, the Gregorian calendar has shaped the life of a large part of humanity. Adopted in 1582 to correct the drift of the Julian calendar, it gradually became the global standard for civil, scientific, and economic activities. Its remarkable astronomical accuracy largely explains its longevity and success. However, it is not without structural oddities and inconsistencies. Many of its features, inherited from superstitions and religious beliefs rather than logic, create practical difficulties and have long fueled proposals for reform.
The time has come to pay special attention to the oddities that our calendar still carries. Here are the main quirks that justify a serious and modern revision of the Gregorian calendar currently in use.
So why change our calendar ?
1. The Gregorian calendar, an unfinished reform :
Introduced about 440 years ago, the Gregorian calendar was a big step forward in organizing time. Yet, this reform didn’t go all the way: it kept several flaws inherited from the Julian and Roman calendars, which are more than two thousand years old.
2. The month of February, a strange month:
With its 28 days, February is a real oddity. This peculiarity goes back to the Roman calendar, which at the time had 355 days—four months of 31 days, seven of 29 days, and one month of 28 days. The Romans, being superstitious, believed that even numbers brought bad luck. So they favored months with an odd number of days. However, to reach a total of 355 days, there had to be a month of 28 days. February, associated with the dead and funeral rites, was chosen to carry this exception.
It must be said that this old superstition has left a curious mark on our current calendar.
3. Unequal length of months:
The Gregorian calendar has kept a very irregular distribution of days: one month of 28 or 29 days, four months of 30 days, and seven months of 31 days. Why are months different lengths? This irregularity forces us to constantly check the number of days in each month to plan our activities and deadlines.
4. Birthdays always on different days:
In the Gregorian calendar, a birthday changes the day of the week from one year to the next. A birthday that falls on a Monday this year might fall on a Wednesday the following year. This makes it tricky to keep track because annual events, meetings, and activities never fall on the same day of the week from one year to the next.
The Modern Fixed Calendar
The Modern Fixed Calendar is :
• A 13-month calendar with 4 weeks of 7 days each.
•The last week of the year is 8 days long, for a total of 365 days.
•In leap years, the last week of the seventh month is also 8 days long, for a total of 366 days.
•Birthday dates are always on the same day of the week.
•According to the international ISO 8601 standard, the week in the Fixed Modern Calendar starts on a Monday.
•For the sake of neutrality, simplicity, and universality, the names of the days and months in the Fixed Modern Calendar are in Esperanto. Using Esperanto also avoids possible confusion with other calendars.
•Only two possible calendar models, the normal year and the leap year.
FINALLY A LOGICAL, STABLE, AND PREDICTABLE CALENDAR.
Total Predictability : The first day of the week is always a Monday (Lundo) and the last a Sunday (Dimanĉo). Birthdays always fall on the same day of the year.
- Economic Fairness :Each month has exactly the same number of working days. No more loss-making Februarys and overloaded Marches for businesses.
Unity Through Language : By using Esperanto (Lundo… Dimanĉo), the calendar becomes neutral and accessible to all, without favoring any specific culture.
Mathematical Simplicity: A year of 13 months of 28 days, plus one extra day at the end of the year, is simple and repetitive math. No more puzzle-solving calendars.
The oddities of the gregorian calendar
Unequal months
Even after several revisions, the calendar is still composed of unequal months, designed on the basis of superstition or religious beliefs:
– 7 months of 31 days
– 4 months of 30 days
– 1 month of 28 days (or 29 days)
A wide variety of anual calendars
There are fourteen different versions of the Gregorian calendar. The current design of the calendar means that consecutive years are all different and birthdays always fall on different days.
Why the Fixed Modern Calendar?
To meet the needs of today’s society, it is necessary to bring order to our calendar and offer a more structured option, free of ambiguities and accessible to all people.
It is to meet this need that the Modern Fixed Calendar was designed: a clean, uniform, and repetitive calendar. The names of the days and months are in Esperanto, a universal language accessible to all people.
The Modern Fixed Calendar, a calendar full of common sense
In conclusion
What if our time finally became simple ?
Today, our calendar is irregular, unpredictable, and unnecessarily complex. Months vary, dates shift, and planning becomes a challenge.
The Modern Fixed Calendar changes everything.
13 months of 28 days. 4 perfect weeks per month. Every date falls on the same weekday, every year. A clear, stable, and logical structure—ideal for work, education, and everyday life. The names of the days and months in Esperanto, a language accessible to all.
And to mark the passage of time, a unique day—Ĝis—concludes the year, outside the weekly cycle, as a universal moment of transition. So less confusion and more consistency.
With the Modern Fixed Calendar : Time finally mastered.
