Nobody was born on October 5th in 1582

During the Middle Ages, astronomers and mathematicians observed that the calendar year was not completely accurate with matching solar years. Errors in the Julian calendar were noted by church officials and scholars because church holidays did not occur in their appropriate seasons.

In 1582, Pope Gregory XIII, and his astronomer and mathematician created a new, reformed calendar known as the Gregorian or New Style calendar. It was adopted first in Roman Catholic countries. Protestant countries adopted the calendar during the eighteenth century.

In order to make the calendar adjustment in 1582, ten days were eliminated from October. October 4th was followed by October 15th.

weird.
