Hagemaier, a German man, set the world record for the longest birthday in history. On his birthday, he flew over three time zones and international international date line. As a result, he spent 46 hours on his birthday. He successfully broke the old record of 35 hours and 25 minutes set by a Pakistani in 1998 and became the longest birthday person in history.

It is reported that Hagemaier first arrived in New Zealand, and then set off from Auckland, New Zealand, to start his historic 26-year-old "birthday trip". He went to Brisben, Australia, and then flew to Hawaii. The actual flight hours of this trip were 13 hours and 11 minutes. However, because the plane flew over the International International DateLine, the result was like going back in time. He spent nearly a whole day longer than others, and spent a full 46 hours. The international international date line was stipulated at the International Longitude Conference in 1884 to avoid the confusion of dates. This change line is located on the 181 meridian in the Pacific Ocean, which is the dividing line between "today" and "yesterday" on the earth. It starts from the North Pole, passes through the Bering Strait, the Pacific Ocean and reaches the South Pole. According to the regulations, when crossing this change line, the date will change: when crossing this line from east to west, the date will be added by one day, and when crossing this line from west to east, the date will be subtracted by one day.
