Sven Hagemeier kept his birthday going for almost two days by crossing between different time zones, on August 4, last year.
Over the course of 46 hours, Sven flew from Auckland (New Zealand), to Brisbane (Australia) and then to Honolulu (Hawaii), achieving a record for the longest birthday ever.
Sven's elongated birthday celebrations beat the previous record set by Nargis Bhimji of Karachi, who celebrated her birthday for 35 hours 25 minutes by crossing time zones after flying from Karachi to Singapore and then to San Francisco back in June 1998.
Sven's extended-birthday highlight was landing in Hawaii at midnight, with the knowledge that he had successfully set the record.
Sven described his Guinness World Records certificate as 'an incredible present'.
This year, however, Sven celebrated his birthday in a low-key manner at home with just his family.
