It depends on the definition of a “day” that you use, but due to Mercury’s elliptical orbit sunrises and sunsets are weird. [1] It takes 59 Earth days for the planet to revolve once around its axis, but from the surface it takes 176 Earth days to observe the sun making a complete circuit of the sky.

This is the weirdest thing at that link:

> But when Mercury is moving fastest in its elliptical orbit around the Sun (and it is closest to the Sun), each rotation is not accompanied by sunrise and sunset like it is on most other planets. The morning Sun appears to rise briefly, set, and rise again from some parts of the planet's surface.
