Seasonal Countdowns
Live countdowns to the first day of every season — updated every second based on the exact astronomical start date in your year.
Each of the four seasons brings its own character: the long bright days of summer, the colorful transition of fall, the stark beauty of winter, and the renewal of spring. Knowing exactly when each season begins helps you plan vacations, wardrobe transitions, outdoor activities, and holiday preparations. The astronomical seasons — defined by solstices and equinoxes — shift slightly each year, which is why a live, calculated countdown is more accurate than relying on a fixed date. Whether you're counting down to the first beach day of summer or the first snowfall of winter, you'll find the precise answer here.

Frequently Asked Questions
When does each season officially start?
Seasons are defined astronomically by solstices and equinoxes. Summer begins at the summer solstice (~June 21), fall at the autumnal equinox (~September 22), winter at the winter solstice (~December 21), and spring at the vernal equinox (~March 20). These dates vary slightly each year based on Earth's orbit.
Do seasons start on the same date every year?
No — the exact dates vary by 1–2 days each year due to Earth's elliptical orbit and the 365.25-day solar year. The countdown on each seasonal page calculates the precise start time for the current year automatically.
Are seasonal dates different in the Southern Hemisphere?
Yes. Seasons are reversed in the Southern Hemisphere. When it's summer in North America and Europe (June–August), it's winter in Australia, New Zealand, and South America. The astronomical dates (solstices/equinoxes) occur on the same calendar days globally, but their seasonal meaning is opposite.
What is meteorological vs. astronomical season start?
Astronomical seasons start at solstices and equinoxes (the dates above). Meteorological seasons are defined by calendar months for convenience: spring is March–May, summer is June–August, fall is September–November, and winter is December–February. The countdowns on this site use astronomical dates.
