A day longer than a year
4,222.6hoursis a day on Mercury, from noon to noon
On Mercury it takes 4,222.6 hours for the Sun to return to the same point in the sky – about 176 Earth days. A Mercury year has only 88 days. So a day there lasts as long as two Mercury years.
On Neptune you stay zero forever
A Neptune year lasts 59,800 Earth days, about 164 Earth years. Even someone who lives to 100 wouldn't have had their first birthday there.
