As Pope, Gregory XIII played a pivotal role in the implementation of the Gregorian calendar, which is still widely used today. The Gregorian calendar sought to correct inaccuracies in the Julian calendar and bring the date of Easter closer to the spring equinox. This reform was crucial in ensuring the consistency and accuracy of timekeeping worldwide.
Additionally, Gregory XIII oversaw various religious and political initiatives. He actively supported Catholic missions in foreign lands, including the establishment of seminaries and colleges to educate clergy for missionary work. He also aimed to counter the influence of Protestantism through embracing the Counter-Reformation and convening the Council of Trent.
Gregory XIII is perhaps best remembered for his commissioning of the construction of the magnificent Gregorian Tower on the Vatican Hill, commonly known as the Tower of the Winds. This tower contained various astronomical instruments and served as a hub for scientific observations and calculations. His interest in science reflected his belief in the harmony and interaction between faith and reason.
Overall, Gregory XIII is hailed as an influential and progressive Pope who left a lasting impact on the Catholic Church and the world at large, particularly through his contributions to calendar reform and support for Catholic missions.
