📅 When Is the First Day of Summer 2025?
The first day of summer 2025 in the Northern Hemisphere will occur on Friday, June 20, 2025. This date marks the summer solstice, the longest day of the year in terms of daylight hours.
The summer solstice typically occurs between June 20 and 22 each year and is determined by the Earth’s tilt and orbit around the Sun. On this day, the Sun reaches its highest position in the sky at noon, offering the most daylight hours of any day in the calendar year.
🌍 What Is the Summer Solstice?
The summer solstice is an astronomical event that signals the transition from spring to summer. Scientifically, it occurs when one of the Earth’s poles has its maximum tilt toward the Sun. For those in the Northern Hemisphere, this means that the sun will be directly overhead at the Tropic of Cancer, delivering extended daylight hours.
For people in regions closer to the equator, the difference in daylight may not be dramatic. However, in places like northern Europe or Canada, the sun can remain visible until almost midnight, making it a truly awe-inspiring phenomenon.

🔎 Why Does the Date of the Summer Solstice Change?
If you’re wondering why the first day of summer 2025 isn’t always the same, the answer lies in how the Earth orbits the Sun. Our calendar year doesn’t exactly align with the time it takes for the Earth to complete one orbit (365.24 days), so leap years and minor variations cause the solstice date to shift slightly.
This is why when does summer start 2025 isn’t always the same as it was in previous years. In 2024, for example, summer began on June 20. In 2026, it may fall on June 21.
