What angle would earth's tilt need to be in order for there to be no seasons on earth?

For Earth to have no seasons, the axial tilt would need to be 0 degrees, meaning the Earth's axis would be perpendicular to its orbital plane around the Sun. This would result in the Sun's rays hitting the Earth's surface evenly throughout the year, with no variation in the amount of sunlight received by each hemisphere. However, this would also mean that there would be no variation in day length or temperature between different regions of the Earth.
