What country has both day and night at a time?

Countries near the poles, such as Norway and Canada, experience phenomena known as the Midnight Sun and Polar Night, where it can be daytime in one part of the country while nighttime occurs in another. During summer months, areas within the Arctic Circle have continuous daylight, while in winter, some regions experience extended darkness. This unique situation allows for both day and night to coexist in different regions of the same country simultaneously.
