* Titan's rotation period: Titan takes approximately 16 Earth days to rotate once on its axis. This means that a Titan day is 16 Earth days long!
* Titan's orbital period: Titan takes 29.5 Earth days to orbit Saturn. This means that a Titan year is also 29.5 Earth days long!
Because Titan's rotation and orbital periods are so similar, the length of a Titan day and night is roughly equal to half its year.
So, while Titan experiences a day and night cycle, it's a very long one compared to Earth's!
