So let’s cut to the chase: the first day of fall 2027 officially starts with the autumnal equinox.

The Big Date: When Exactly Is the First Day of Fall 2027?
Mark your calendars but keep them flexible—fall will kick off on Wednesday, September 22, 2027, with the autumnal equinox at precisely 3:45 AM UTC (give or take a few seconds).

This is not just pulled out of thin air. Observing the precise timing of equinoxes is the territory of astronomers and those calendar wonks who track the Earth’s tilt and orbit around the Sun. According to various astronomical data, including the precise calculations housed in resources like Britannica’s explanation of fall’s start, the equinox happens when the Sun crosses the celestial equator heading south. That’s what officially flips the switch from summer to fall.
Why Does the Date Shift? A Little Science and History
Here’s the catch: the first day of fall isn’t a fixed calendar date. No, the Earth doesn’t care about our neat Gregorian calendars. Because the Earth’s orbit around the Sun isn’t a perfect 365-day cycle but about 365.24 days, the date the equinox arrives hops between September 22 and 23, sometimes even showing up on the 21st or 24th in rare cases.
So, if you’re living by your office calendar, you might be surprised to learn that fall starts a day earlier or later some years. The Columbia University Registrar’s calendar demonstrates how academic scheduling gradually accounts for such astronomical shifts to avoid clashes with seasonal changes that impact students’ plans.
How Different Places Watch the First Day of Fall
- In the Northern Hemisphere, people embrace autumn on or around the equinox, welcoming shorter days and cooler weather. Everyone from pumpkin farmers to university students marks this switch, as seen in the thorough USC Academic Calendar, which aligns semesters with seasonal changes.
- Meanwhile, the Southern Hemisphere is waving fall goodbye and gearing for spring. Their seasonal dance runs backwards relative to ours — weird but absolutely true.
- Traditional and cultural celebrations often latch onto this date or the general season, from harvest festivals in rural towns to spirited college homecoming weeks that typically happen in early October, timed after the shift into fall.
When Will Fall officially End Then?
Fall struts into the spotlight around the equinox and sticks around until the winter solstice, which in 2027 looks to drop on December 21. So you have between September 22 and December 21 to bask in pumpkin-spiced everything.

- The word “equinox” means “equal night,” highlighting how day and night are roughly equal at this time. But this doesn’t mean precisely 12 hours of daylight everywhere — weather, latitude, and atmospheric conditions play tricks.
- Each year, the days get shorter and cooler, pushing temperatures down slowly but surely — the perfect nudge for sweater season to kick in.
- Falling leaves, crisp morning air, and football games: you know fall has arrived not just by the calendar but thanks to these unmistakable signs.

FAQs about the First Day of Fall 2027
What time does fall start in 2027?
Fall begins on September 22, 2027, at about 3:45 AM UTC when the autumnal equinox occurs.
Why does the first day of fall change every year?
The Earth’s elliptical orbit and extra fraction of a day in the calendar year cause the fall equinox to shift between September 22 and 23. This adjustment happens because our calendar isn’t perfectly aligned with Earth’s revolution.
Does everyone experience the first day of fall at the same moment?
The astronomical event happens simultaneously worldwide at the exact UTC time, but local clocks translate it differently depending on time zones.
How do universities plan academic calendars around seasonal changes?
Institutions like USC and Columbia University consider equinoxes and solstices to schedule semesters thoughtfully, ensuring that breaks and semesters align with seasonal expectations and daylight shifts.
Is the first day of fall the same as Labor Day?
Nope. Labor Day in the U.S. is celebrated on the first Monday in September and often marks the unofficial end of summer, but fall officially starts later during the autumnal equinox.
