About This Event

When Does Summer Start?

Summer marks one of the four major seasonal transitions. This astronomical turning point brings changes in day length, weather, and nature that affect daily life.
Many people plan their activities and vacations around the change of seasons. Our countdown shows you exactly how many days remain so you can prepare accordingly.
Did You Know?
  • The astronomical seasons are caused by Earth's 23.5-degree axial tilt, not by our distance from the Sun. In fact, Earth is closest to the Sun in early January during the Northern Hemisphere's winter.
  • Seasonal changes affect more than weather. Research shows that human creativity, sleep patterns, and even immune function fluctuate with the seasons.
  • The length of a day changes fastest around the equinoxes — gaining or losing 2–3 minutes of daylight per day near March and September 21.
