Who was father of the leap year?

Answer 1

The concept of the leap year is primarily attributed to Julius Caesar, who introduced the Julian calendar in 45 BCE. This calendar included an extra day every four years to account for the fact that a year is not exactly 365 days long. However, the modern leap year system, which refines the calculation further, was established by Pope Gregory XIII with the Gregorian calendar in 1582. Thus, while Julius Caesar is often seen as the father of the leap year concept, Pope Gregory XIII played a crucial role in its evolution.
