Very simply, because "no night" and "polar day" are quite different events. "No night" means there is always a little bit of light even at midnight, but the sun is UNDER the horizon (at midnight). "Polar day" is the period of the year when the sun always remains visible well above the horizon for the whole night and there is no sunset.
For example, on June 22nd you will experience polar day at Tromsø and "no night" in some cities such as Helsinki or Saint Petersburg![]()

Perfect !
