No never, not ever!
One of the hardest problems of all when designing a fictional solar system is to create one where a planet is warm enough for life, and is habitable for humans, and has either eternal night or eternal day all over the planet's surface.
It is really easy to design a solar system where the closer planets are tidally locked to their star, meaning that their rotation periods and orbital periods are the same. Thus one side of such a planet will always face their star and have eternal day, while the other side of such a planet will always face away from it's star and have eternal night.
it is believed that there should be many billions of such planets in our galaxy. It is uncertain whether such planets could be habitable, but if a significant percentage of such planets are habitable then they should be very numerous in our galaxy.
So if you want one side of your planet to have eternal day while the other side has eternal night, that's really easy.
If you want eternal night all over your fictional planet, that can be easy. You can just make your fictional planet a rogue planet that is not in any solar system but is in interstellar space instead, and thus is lit only by dim starlight in its eternal night. Astronomers believe there are many billions of rogue planets in our galaxy, far from the heat of any star and thus with temperatures just a little bit above absolute zero.
Temperatures just a little bit above absolute zero! What if you want to have Earth like life on your planet requiring Earth like temperatures, large multi celled lifeforms, or intelligent natives, or a world habitable for Earth humans? Then you are out of luck with a rogue planet, unless you can imagine or learn about any theories about how a rogue planet could have eternal night and also Earth like temperatures.
Of course any planet, whether in a solar system or a rogue planet, could have eternal day if an advanced civilization decided to make that happen. They could put a number of gigantic space stations in orbit around the planet. Each space station would have countless gigantic fusion power generators generating vast amounts of electricity to power countless giant lamps pointed at the planet. If enough of those "Sun Satellites" were in orbit around the planet at least one at a time would always be visible from every place of the planet's surface, and every place on the planet's surface would have eternal day.
Isaac Asimov wrote a famous science fiction story "Nightfall" where the planet Kalgash had eternal day over its entire surface. There were six stars in the Kalgash system, and so there were always at least one or two of them above the horizon everywhere on the planet.
Except that once every two thousand Kalgash years the orbits of Kalgash and the stars would put only one star on one side of Kalgash and the other five stars on the other side of Kalgash. And at the same time, a large moon of Kalgash would eclipse the only star on that one side of Kalgash and plunge that side of Kalgash into the first darkness in 2,000 years. And the eclipse would last so long that the rotation of Kalgash would turn the whole half of Kalgash that had been facing the other five stars at the beginning of the eclipse to face the one single star that was eclipsed, and so that other side of Kalgash would also face hours of darkness for the first time in 2,000 Kalgash years.
Would the Kalgash system be possible?
Astronomers have identified many multiple star systems, including some, like Castor, that have six stars, and even two with seven stars. s astronomers have learned a lot about the orbital dynamics of multiiple star systems and the possible orbits of hypothetical habitable planets in them, etc.
PlanetPlanet is a blog 'about where planets come from and where they are going". And it has a section where the blogger Sean Raymond discusses the plausibility of various solar systems in science fiction. And that includes two posts where Raymond tries to design a workable version of the Kalgash system:
And you can see that Raymond had a lot of trouble designing a realistic Kalgash system.
And you could take some of his proposed solutions as the basis for a habitable world which is always in eternal day all over the planet. Even though it seems extremely improbable for some of those solar systems to form naturally.

Or you could have your fictional solar system happen by chance to pass through a "stellar nursery" as both orbit around the center of the galaxy. It could take your solar system many thousands or even millions of years to pass through the "stellar nursery". A "stellar nursery" is a giant nebula of dust and gas that is condensing to form stars and solar systems. And as the stars form and begin to shine some of their light should be reflected off dust and scattered in all directions, and some of their light should make the gas emit its own light.
And if your solar system has been light years deep within that "stellar nursery" for thousands or millions of years, maybe the light from all around the solar system might be intense enough to make a difference on the planet. It is possible that, for example, if the background light from the gas and dust in the dense nebula is at least one percent of the intensity of the light of the planet's star, when the planet's star sets the sky won't get as dark as it would on Earth and the sky will remain blue, though much darker, and other stars will not be visible, and it will seem more like a very dim Earth day than like an Earth night.
But I have not calculated whether it would be possible for such a dense and bright nebula to illuminate the planet that much and I don't know if that is possible.
Another possibility is that a globular star cluster is passing though the galactic disc, and its orbit and the orbit of your solar system happen to intersect. It could take your solar system many thousands of years to pass through the dense central region of that globular star cluster, and for all that time the combined light from the thousands of closest stars might possibly be intense enough to make the night on your planet look more like a very dim day on Earth.
But again, I have not made calculations to see whether the light in the core of a globular star cluster could be intense enough. Possibly you could get some other user here to do such calculations for you.
