Days Until Spring 2026 - Spring Equinox Guide

What Is the Vernal Equinox?

The vernal equinox (from Latin "vernalis" meaning springand "aequinoctium" meaning equal night) is the precise moment when the Sun crosses the celestial equator moving northward. At this instantthe Earth's axial tilt is neither toward nor away from the Sunresulting in nearly equal amounts of daylight and darkness at all latitudes.

In 2026the vernal equinox occurs on March 20. The exact timing varies slightly each year because Earth's orbital period is not precisely 365 days. The equinox can fall on March 1920or 21 depending on the year. For more detailed astronomical datavisit the National Weather Service or timeanddate.com.

Key scientific facts about the vernal equinox:

• Equal day and night: On the equinoxevery location on Earth experiences approximately 12 hours of daylight and 12 hours of darkness. In practicerefraction of sunlight through the atmosphere means sunrise occurs slightly before the geometric sunriseso most locations experience a few minutes more than 12 hours of light.
• Sun rises due east: On the equinoxthe Sun rises exactly due east and sets exactly due westregardless of your latitude.
• Fastest daylight change: The rate of change in daylight length is greatest around the equinoxes. Locations at mid-latitudes gain about 2-3 minutes of daylight per day in the weeks around the vernal equinox.
• Southern Hemisphere: When it is the vernal (spring) equinox in the Northern Hemisphereit is the autumnal (fall) equinox in the Southern Hemisphereand vice versa.
• Celestial equator crossing: The Sun's declination changes from negative (south of the celestial equator) to positive (north of it) at the moment of the vernal equinox.

Astronomical vs. Meteorological Spring

There are two widely recognized definitions of springand they start on different dates. Understanding the distinction helps clarify weather forecastsseasonal referencesand planning activities.

Meteorologists prefer the March 1 start date because it aligns seasons with complete calendar monthsmaking it easier to compare weather statistics and climate records across years. Most peoplehoweverrefer to the astronomical equinox as the "official" start of spring. The National Oceanic and Atmospheric Administration (NOAA) uses meteorological seasons for all climate reporting.

Spring Equinox Dates 2024-2030

The vernal equinox shifts slightly from year to year due to the interplay between Earth's 365.25-day orbital period and the calendar. Leap years cause the equinox to arrive slightly earlierthen it drifts later over the following three years. Here are the spring equinox dates for the Northern Hemisphere from 2024 through 2030.

Notice that in leap years (2024 and 2028)the equinox tends to fall on March 19 rather than March 20. The last time the vernal equinox fell on March 21 in the U.S. was in 2007and it will not happen again until 2101.

2026 Season Dates - All Equinoxes and Solstices

The four seasons are defined by two equinoxes and two solstices. Here are the exact dates for all astronomical season changes in 2026 for the Northern Hemisphere.

Note that the seasons in the Southern Hemisphere are reversed: when it is spring in the Northern Hemisphere (March-June)it is autumn in the Southern Hemisphereand vice versa.

Daylight Changes Through Spring 2026

One of the most noticeable effects of spring's arrival is the rapid increase in daylight hours. Here is how daylight changes at various latitudes across the United States during the spring months.

At higher latitudesthe change in daylight is more dramatic. AnchorageAlaska gains over 9 hours of daylight between March 1 and the summer solsticewhile Miami gains only about 2 hours during the same period. Track the exact number of days between any two dates with our date calculator.

• Holi (Hindu Festival of Colors): Celebrated in MarchHoli marks the arrival of spring with vibrant colorsbonfiresand community celebrations across India and Nepal.
• Easter: The most important Christian holidayEaster celebrates the resurrection of Jesus Christ. Its date is calculated based on the first full moon after the vernal equinox.
• Cherry Blossom Festivals: Japan's "Hanami" tradition involves picnicking under blooming cherry trees. WashingtonD.C. also hosts a famous National Cherry Blossom Festival each spring.
• May Day (May 1): Celebrated across Europe with maypole dancingflower crownsand spring festivals marking the midpoint of spring.
