How Many Days Until The Next Season?

Start of Winter Season
Winter begins in December in the Northern Hemisphere, the coldest and darkest time of the year.
Start of Spring Season
Spring begins in March in the Northern Hemisphere, bringing warmer days and new growth.
Start of Summer Season
Summer begins in June in the Northern Hemisphere, the warmest season with the longest days.
Start of Fall Season
Autumn begins in September in the Northern Hemisphere, bringing cooler days and falling leaves.
What Are the Four Seasons?
The four seasons are spring, summer, autumn, and winter. Each one covers about three months of the year and brings its own weather, daylight length, and natural changes, forming a cycle that repeats every year.
This steady rhythm has shaped life on Earth for as long as it has existed. Spring and autumn begin on the equinoxes, when day and night are almost equal in length. Summer and winter begin on the solstices, marking the longest and shortest days of the year. Together, these four turning points form the natural flow of the calendar.
It is worth knowing that the seasons are flipped between the two halves of the world. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and the same goes for spring and autumn.
Astronomical vs Meteorological Seasons
There are actually two ways to define the seasons, and they do not start on the same day.
Astronomical seasons are based on the Earth's position relative to the Sun, using the equinoxes and solstices. These are the dates our countdowns follow, and they shift slightly from year to year.
Meteorological seasons are simpler. They group the year into fixed three-month blocks based on the annual temperature cycle, which makes them easier for weather forecasting. Our tracker uses the astronomical dates, as they mark the true, official start of each season.
