President's Day is in February. However, only four presidents were born in this month. It just so happens that two of America's most prominent presidents were born in February, Washington and Lincoln. The two other presidents that share this birth month are Ronald Reagan and William Henry Harrison.
The month with the most presidential birthdays is October with six. The presidents born this month are John Adams, Rutherford B. Hayes, Chester A. Arthur, Theodore Roosevelt, Dwight David Eisenhower and Jimmy Carter. Interestingly enough, the second most popular month for presidential birthdays is November with five.
The most sparse month is a tie between June and September, each claiming only one president. June claims George H.W. Bush, and September has William Howard Taft.
Can we make anything from this skewed distribution of birthdays? Perhaps and perhaps not. 42 total presidents (43 if you count Cleveland twice, as many do, because of his separate terms of office) may not be a large enough sample to create a scientific conclusion regarding birth-months. Yet, we can say that the spring months, taken together, have a dearth of births. This could be because many of the early presidents had fathers who participated in historic events, which usually occurred in the summer months. This would mean these men were more likely to be absent from home at the crucial moment nine months before the spring season.
