Many people wonder when spring actually starts. Does it make its debut on March 1st, or does it officially get marked on the calendar later on in March when it is the 'spring equinox'? You're about to find out this and many other interesting facts about the equinox and the proper start of one of the most beautiful and yearned-for seasons of the year.
When Does Spring Start and What Is the First Day of Spring in 2026?
The first day of spring in 2026 will officially begin on Friday, March 20th, at exactly 15:46 (CET), marking the arrival of the spring equinox. This astronomical event occurs when the Earth’s tilt and orbit align in such a way that the Sun crosses the celestial equator, resulting in nearly equal hours of daylight and darkness across the globe.
For those who closely follow the changing seasons, the spring equinox is more than just a date on the calendar because it signifies the official transition from winter to spring in the Northern Hemisphere and from summer to autumn in the Southern Hemisphere. Interestingly, the equinox doesn’t fall on the same date every year due to the way our modern calendar accounts for leap years and the Earth’s slightly irregular orbit around the Sun.
The Spring Equinox Explained
The spring equinox in the Northern Hemisphere (also called the March equinox or vernal equinox) occurs when the sun crosses the celestial equator going from south to north. It’s called the “celestial” equator because it’s an imaginary line in the sky above the Earth’s actual equator.
During this event, the Northern and Southern Hemispheres receive roughly equal amounts of sunlight, with neither tilted toward nor away from the Sun. Did you know that the equinoxes are the only two times each year that the Sun rises due east and sets due west for everyone on Earth?
After the winter solstice, the amount of daylight increases each day in most places. Once the equinox passes, many regions will see more daylight than darkness up to the summer solstice in June.

Does Spring Begin on March 1st or During the Equinox?
When people ask this, the answer can be both, depending on how 'spring' is defined. Meteorologically, spring starts on March 1st in many parts of the world – but astronomically, spring begins with the equinox, which can fall on March 19, 20, or 21 every year. Also, because of time zone differences, some places observe the equinox on one calendar date and the astronomical moment on another. For example, the U.S. won’t see an equinox on March 21 again until 2101.

Daffodils – The Official Spring Flower
The daffodil (Narcissus) is the March birth flower. It represents rebirth and renewal and is also known as the 'flower of spring'. Native to the Mediterranean region, daffodils thrive in temperate climates and are remarkably resilient. These trumpet-shaped flowers return year after year, even after harsh winters, which further reinforces their association with perseverance and hope. Beyond yellow, daffodils can also be found in shades of white, cream, orange, and even soft pink, making them versatile favorites in gardens and floral arrangements alike.
In many cultures, daffodils are believed to bring good fortune and prosperity, especially when seen blooming in clusters. They are commonly planted in parks, gardens, and along roadsides, creating sweeping displays that celebrate the official arrival of spring. Whether growing wild or carefully cultivated, daffodils remain a reminder of nature’s ability to renew itself with every changing season.
Fun Ideas to Start the Upcoming Spring Season
Here are some ways to welcome the blooming season:
- Watch the arc of the Sun shift northward in the sky as the days get longer.
- Notice birds migrating north – a classic sign of spring.
- Enjoy the sunset earlier or later each day.
- Spot daffodils, Campanulas, and other early flowers emerging.
- Start your gardening plans in preparation for warmer days.
As spring unfolds, attention naturally turns to the breathtaking tulip fields of the Netherlands, where endless rows of color come alive during the season. These iconic landscapes capture everything spring represents: renewal, creativity, and the joy of flowers in full bloom.
