When Is the First Day of Summer 2025? Everything You Need to Know About the Summer Solstice

New York: There’s something timeless about the first day of summer. It’s when sunlight lingers a little longer, the sky turns that perfect shade of gold, and everything feels a bit more alive. Whether you’re reminiscing about last year’s beach trip or planning your next summer adventure, the season’s start always carries a quiet kind of magic.

But while many of us mentally switch into summer mode by June 1st, the true first day of summer—according to the Earth and stars—is a bit more precise. That moment is the summer solstice, when our planet tilts perfectly to let the Sun beam down on the Northern Hemisphere longer than any other day of the year.

So, when exactly is the first day of summer 2025? What’s so special about this solstice, and how can you make the most of it? Whether you’re a skywatcher, a sun lover, or just someone craving warmth and light, here’s everything you need to know.

When Is the First Day of Summer 2025?

The first official day of summer 2025—known as the summer solstice—falls on Friday, June 20, 2025, at 10:42 PM Eastern Time. This is the exact moment when the Northern Hemisphere is tilted most directly toward the Sun.

Depending on your time zone, this event may technically fall on June 21 in places like the UK and Europe. But for most of the U.S., June 20 is your moment to mark on the calendar.

What Is the Summer Solstice?

The summer solstice is the longest day of the year. It’s the point when the Sun appears highest in the sky at noon, and daylight stretches to its maximum. After this day, sunlight hours gradually begin to shrink—but don’t worry, we still get weeks of summer sunshine ahead.

This celestial moment happens because of the Earth’s 23.5-degree axial tilt. When the North Pole tilts toward the Sun, we in the Northern Hemisphere get our brightest day—and the spiritual “welcome mat” to summer.

Solstice vs. Meteorological Summer: What’s the Difference?

You might’ve heard that summer “starts” on June 1st—and you’re not wrong! That’s the meteorological summer, a simplified seasonal system used by weather experts. It spans from June 1 to August 31.

The astronomical summer, however, begins with the solstice and runs until the autumn equinox (September 22, 2025). Both calendars are valid—it just depends on whether you’re following climate patterns or cosmic timing.
