A planet orbiting both stars in a binary system could have two suns in its sky, but the number of stars alone does not determine its daylight schedule or seasons. Those depend on the stars’ motion and brightness, the planet’s orbit and rotation, its axial tilt, and its atmosphere. No confirmed Earth-like circumbinary world has an established surface daylight calendar or seasonal pattern.
How two suns would change the sky
A planet that orbits both stars is called circumbinary: the stars orbit their shared center of mass, and the planet travels around the pair. Depending on the system’s geometry, a person on a suitable solid world could see both stars, sometimes at different apparent positions in the sky. Their changing positions and relative brightness would affect illumination and shadows.

NASA/JPL’s account of Kepler-16b describes a sky with two suns. In that system, the stars orbit each other every 41 days, while Kepler-16b takes 229 days to orbit both stars. These are periods for Kepler-16, not a standard schedule for all circumbinary planets. NASA/JPL: Kepler discovers its first planet orbiting two stars.
Kepler-47 provides a different example: NASA says its stars eclipse each other every 7.5 days as seen from Earth, and the outer planet Kepler-47c takes 303 days to orbit the pair. Those figures describe that system and do not give a hypothetical planet’s local sunrise or day length. NASA Science: Kepler-47c.

What daylight and sunrise might be like
There is no universal circumbinary day. To calculate local daylight hours, sunrise, or sunset, you would need to know the planet’s rotation, its axial orientation, its orbit, and the stars’ positions and brightnesses. Depending on those details, the two stars could appear close together or far apart, and their contribution to the sky’s brightness would vary as the system moves.
The 41-day and 229-day Kepler-16 periods and the 7.5-day and 303-day Kepler-47 periods are orbital or eclipse timings, not the rotation periods of a surface on those planets. Without a specified spin and system geometry, assigning exact daylight hours or a sunrise timetable would be guesswork.

What would determine the seasons?
Seasons would depend on more than having two stars. A planet’s axial tilt and orbital shape affect how sunlight changes over its year; the combined energy from both stars matters too. Its atmosphere and climate determine how that energy is retained and distributed. The stars’ orbital motion can also add shorter-term changes in received energy, while gravitational interactions can alter a planet’s orbit or orientation over longer timescales.

Two real planets—and the habitability caveat
Confirmed circumbinary planets show that planets can orbit both stars, but the examples do not establish what seasons would feel like on an Earth-like surface. Kepler-16b is a cold, Saturn-sized gas giant outside its system’s habitable zone. Kepler-47c is a gas giant slightly larger than Neptune that lies in its system’s habitable zone, yet NASA describes it as not hospitable for life.
A habitable zone is a model-based range of orbits where liquid water could be possible under suitable conditions. It does not prove that a planet has a solid surface, surface water, breathable air, or life. Nor do these examples establish an Earth-like moon or rocky planet in either system.
