Now that Lunar eclipse has passed, March Equinox, a global astronomical event will take place on 20th March 2026. This event will be seen "worldwide". At that instant, the Sun shines directly over the Equator and nearly equal hours of day and night occur worldwide.

This marks the first day of spring in the Northern Hemisphere and the start of autumn in the Southern Hemisphere. The day and night during equinox would nearly be equal in length worldwide. This is a gentle reminder of the Earth’s axial tilt.

When the 2026 spring equinox will occur?

In 2026, the March equinox will occur on March 20 at 09:46 a.m EST. At that exact moment, the Sun will be positioned directly above Earth’s equator.

This alignment causes sunlight to fall almost evenly across both hemispheres, creating nearly equal lengths of day and night worldwide.

For observers around the globe, the days following the equinox will gradually become longer in the Northern Hemisphere and shorter in the Southern Hemisphere.

Where will the March equinox be seen?

The March equinox will be witnessed "worldwide". Unlike eclipses or meteor showers that are visible only from certain regions, the equinox affects every location on the planet.

During this moment, the Sun crosses the celestial equator, moving from the southern half of the sky to the northern half. The day and night on 20th March will become nearly the same length worldwide.

Why day and night are nearly equal?

Around this time, the length of daylight and darkness becomes almost the same across the planet. However, scientists point out that day and night are not perfectly equal.

This is because of atmospheric effects and the way sunlight bends as it passes through Earth’s atmosphere. Still, the equinox remains the closest point in the year when both halves of the planet receive nearly the same amount of sunlight.

What changes in the sky during the equinox?

The equinox also brings some interesting sky-related effects. The sunrises and sunsets occur more quickly around the equinox compared with other times of the year.

The boundary between day and night across Earth, known as the terminator line, also becomes nearly vertical, stretching from the North Pole to the South Pole.

Will India see the March Equinox?

Yes, India will also experience the effects of the March equinox, just like the rest of the world. This event will take place on 20th March 2026, when the sun shines almost equally over the world.

For people in India, the sun will rise almost due east and will set almost due west. India will witness this in the evening as per Indian Standard Time at 8:16 p.m. The duration of the day will be almost 12 hours.
