As we can see from this brief history of calendars, one of the key challenges in making any calendar is the decision about how to account for the variations between the calendar year and the solar year, since the latter includes a fraction of a day. The Gregorian calendar improved considerably on the Julian calendar, limiting the discrepancy to one day every 3,336 years. While it is commonly believed that every fourth year is a leap year, the actual rule imposed in 1582 is slightly more complicated: we add a day to February in years that are divisible by 4, but not in years divisible by 100, unless they can be divided by 400. Thus, 1700, 1800 and 1900 were not leap years, but 1600 and 2000 were. This adjustment means that the average calendar year is only 26 seconds longer than a solar year, so it won’t be an issue again until the year 4918
