In fact, Pope Francis received an even larger pizza for his 81st birthday celebration, which measured in at a whopping 13 feet. Besides eating pizza, Francis would typically spend his birthdays with those he sought to serve: the poor and vulnerable. For Pope Benedict XVI’s 80th birthday, Vatican employees got the day off along with a bonus on their paychecks. If one looks at the historical record, celebrating popes’ birthdays seems to be a mostly modern phenomenon. Whether it’s pizza, puppies or partying, hopefully Leo gets some time to enjoy his day.
