If you’ve been wondering when is the first day of spring 2025, you’re not alone. As winter slowly fades and the days grow longer, many people look forward to the fresh start that spring brings. The first day of spring is not just about warmer weather. It marks a special moment in astronomy, nature, and culture.
In this detailed guide, you will learn:
- The exact date of the first day of spring 2025
- Why the date changes slightly each year
- The science behind the spring equinox
- How different countries celebrate spring
- Fun facts, traditions, and seasonal changes
Let’s dive in and explore everything you need to know about when is the first day of spring 2025.
When Is the First Day of Spring 2025?
The first day of spring 2025 in the Northern Hemisphere will be on Thursday, March 20, 2025.
This day is known as the Spring Equinox, also called the Vernal Equinox. On this special day:
- Day and night are almost equal in length
- The sun crosses the celestial equator
- The Northern Hemisphere begins tilting toward the sun
In countries like the United States, Canada, and United Kingdom, March 20, 2025, marks the official start of spring.
If you live in the Southern Hemisphere, however, March 20, 2025, marks the beginning of autumn instead.
So, if someone asks you, “when is the first day of spring 2025?” you can confidently say: March 20, 2025.
What Is the Spring Equinox?
The word “equinox” comes from Latin words meaning “equal night.” On the spring equinox:
- The sun shines directly above the Earth’s equator
- Day and night are nearly equal in length
- The Earth is not tilted toward or away from the sun
To better understand this, imagine the Earth as a spinning top that leans slightly. Throughout the year, that lean changes how sunlight reaches different parts of the world.
During the spring equinox:
- The Northern Hemisphere begins getting more direct sunlight
- Days start getting longer
- Temperatures slowly begin to rise
In simple terms, the equinox is nature’s way of saying, “Winter is over. Spring is here!”
Why Does the Date Change Each Year?
You may notice that the first day of spring is sometimes March 19, March 20, or even March 21. Why does this happen?
It’s because:
- The Earth takes about 365.24 days to orbit the sun
- Our calendar has 365 days in a normal year
- Leap years help adjust the difference
Since the orbit is not exactly 365 days, the equinox shifts slightly each year.
For 2025, the calculation places the equinox on March 20. But in some future years, it could happen on March 19.
Isn’t it fascinating how such a tiny fraction of a day can affect our calendar?
What Happens on Earth During the First Day of Spring?
When we ask when is the first day of spring 2025, we are also asking what changes happen in nature.
Here’s what typically occurs:
Longer Days
- Sunrises happen earlier
- Sunsets happen later
- More daylight boosts energy and mood
Warmer Temperatures
Although it may still feel chilly, temperatures begin rising gradually.
Plants Begin Growing
- Flowers start blooming
- Trees grow new leaves
- Grass turns greener
Animals Become Active
- Birds migrate north
- Bears wake up from hibernation
- Insects reappear
Spring is truly a season of renewal.

This simple image helps explain why the equinox happens. When the Earth’s axis is not leaning toward or away from the sun, day and night are nearly equal.
Meteorological Spring vs. Astronomical Spring
Here’s something interesting: not everyone agrees on when spring begins.
There are two main definitions:
| Type of Spring | Start Date | Based On |
|---|---|---|
| Astronomical Spring | March 20, 2025 | Position of Earth and Sun |
| Meteorological Spring | March 1, 2025 | Calendar and temperature patterns |
Meteorologists prefer March 1 because:
- It makes seasonal weather data easier to track
- It divides the year into four equal parts
- It helps compare temperatures year by year
However, astronomers focus on the equinox, which is why March 20, 2025, is the official answer to when is the first day of spring 2025.
How Different Countries Celebrate Spring
Spring is celebrated in many cultures around the world.
Nowruz in Iran

Even before March 20, you may notice signs of spring:
- Robins returning
