Spring begins today with vernal equinox at 10:46 am ET in 2026

The vernal equinox marks the official start of spring on Hemisfério Norte this Friday, March 20, 2026, at 2:46 pm UTC time, when Sol directly crosses Terra’s celestial equator. Esse astronomical phenomenon results in days and nights of almost equal length across the planet, with around 12 hours each. No Hemisfério Sul, the same event signals the beginning of autumn.

The alignment occurs due to the inclination of approximately 23.5 degrees of the axis of the Terra in relation to the orbital plane around the Sol. Essa position causes the sun’s rays to fall perpendicularly on the equator, balancing the lighting between the hemispheres. Após At this point, the days begin to get longer in Hemisfério Norte, while in Sul the nights gradually lengthen.

The date of the equinox varies slightly between March 19, 20 or 21, depending on the year and calendar. In 2026, the event falls exactly on the 20th. Astronomical spring lasts until the June solstice, lasting approximately 92 to 93 days, influenced by the elliptical orbit of Terra.

Definition and characteristics of the vernal equinox

The vernal equinox, also called the March equinox, represents the point at which Sol passes from the southern hemisphere to the north in the sky. Esse crossing creates conditions of global luminous balance. NASA explains that the phenomenon differs from solstices, in which Sol reaches its most extreme position to the north or south, generating the longest and shortest days of the year.

Astronomers observe that the axial tilt of Terra causes seasonal variations. At the equinox, the distribution of sunlight approaches equality. Isso marks a natural transition between seasons, with observable impacts on the duration of daylight.

Difference Between Astronomical and Meteorological Stations

Astronomical seasons are based on the position of Terra in its orbit around Sol and events such as equinoxes and solstices. Já meteorological stations divide the year into fixed three-month periods to facilitate climate analysis and annual comparisons.

Meteorological spring begins on March 1st and ends on May 31st. Essa division prioritizes temperature data and atmospheric patterns. Meteorology centers adopt this criterion for consistent statistics.

The distinction allows for precise studies in climatology. Enquanto astronomical reflects celestial movements, meteorological meets practical needs for forecasting and historical recording.

Myth of Egg Balancing at the Equinox

Many people believe that balancing an egg vertically is only possible on the day of the equinox due to a special gravitational alignment. Essa idea has been circulating for decades and gains popularity on seasonal dates.

Experts say that balance depends on patience, the shape of the shell and the position of the inner yolk, not on unique celestial forces. Experimentos show that the feat occurs any day of the year with enough practice.

The tradition persists as a cultural curiosity. Fontes scientific evidence denies any significant gravitational variation during the equinox.

Celebrations and rituals in different cultures

Several societies mark the equinox with ancient traditions that symbolize renewal and balance. Na Suíça, communities burn a giant effigy called Böögg, a practice that dates back to Idade Média and represents the end of winter.

In México, in Chichén Itzá, the shadows on the pyramid of El Castillo create the illusion of a serpent descending the steps at dusk. Esse spectacle attracts thousands of visitors annually.

In Japão, Shunbun in Hi involves visiting family graves to honor ancestors. Muitas people clean tombstones and offer flowers on this national holiday.

Asian and Persian traditions associated with the period

In Irã and parts of Ásia Central, Nowruz celebrates the new year with house cleaning, gift exchange, and a ceremonial table called Haft-Seen, which includes symbolic items for prosperity. The festival coincides with the equinox and emphasizes renewal.

In China, some communities try to balance eggs vertically to attract good luck and prosperity in the cycle that begins. Essa practice symbolizes harmony and stability.

The Holi festival, on Índia and Nepal, takes place close to the equinox and involves the throwing of colored powders and water, celebrating the victory of good and the arrival of milder temperatures.

The 2026 equinox reinforces the astronomical importance of this phenomenon, which has influenced global calendars and cultures for millennia. Observações in different regions highlight how the event combines science and tradition.
