Abstract

fetched live from OpenAlex

The Roman calendar was first developed as a lunar calendar, so it was difficult for the Romans to reconcile this with the natural solar year. In 45 BC, Julius Caesar reformed the calendar, creating a solar year of 365 days with leap years every four years. This article explains the process by which the Roman calendar evolved and argues that the reason February has 28 days is that Caesar did not want to interfere with religious festivals that occurred in February. Beginning as a lunar calendar, the Romans developed a lunisolar system that tried to reconcile lunar months with the solar year, with the unfortunate result that the calendar was often inaccurate by up to four months. Caesar fixed this by changing the lengths of most months, but made no change to February because of the tradition of intercalation, which the article explains, and because of festivals that were celebrated in February that were connected to the Roman New Year, which had originally been on March 1.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
