Calendars in antiquity were lunisolar, depending on the introduction of intercalary months to align the solar and the lunar years.
The Julian calendar was no longer dependent on the observation of the new moon but simply followed an algorithm of introducing a leap day every four years.
This created a dissociation of the calendar month from the lunation.
Such ideas are mooted from time to time but have failed to gain traction because of the loss of continuity, massive upheaval in implementation, and religious objections.
A full calendar system has a different calendar date for every day.
