You have to remember your location in the world. Firstly you do not state where you are and the world rotates. It is always night somewhere as it is always day somewhere. Secondly parts of Alaska stretch so far west they cross the anti-meridian and have an eastern longitude. Thirdly Alaska is way up north and it is winter time, so the days are short if they exist at all.
In Alaska there is 6 months day & night

You can say "good night" when it is your day time, if you are talking to a person who is in a country where it is night time. When it is day time in Ireland, it is night time in Australia and New Zealand, and other places.
In Alaska, the longest day occurs on or around June 21st, known as the summer solstice, when the sun is up for about 22 hours. Conversely, the longest night happens on or around December 21st, known as the winter solstice, when the sun may be up for only a few hours in some parts of Alaska.
In the summer months, Alaska experiences long daylight hours with the sun visible for up to 24 hours a day in some northern regions. This phenomenon is known as the Midnight Sun. Conversely, in the winter months, Alaska experiences short daylight hours with extended periods of darkness, known as the Polar Night. The length of the day varies depending on the specific location within Alaska and the time of year.
