Practical answers to complex questions

# Does the equinox happen the same time everywhere?

## Does the equinox happen the same time everywhere?

When measured in sidereal time — time relative to the stars — the equinox happens at the same moment for everyone, but people experience it at different local times.

## Will a solstice or equinox occur at the same time around the world?

This year, the northern summer solstice falls on June 20 at 11:32 p.m. EDT (June 21 at 3:32 UT). South of the Equator, this same moment marks the unofficial beginning of winter. Solstices occur at the same time around the world, but their local times vary with time zones.

Is the equinox the same at all latitudes?

There are only two times of the year when the Earth’s axis is tilted neither toward nor away from the sun, resulting in a “nearly” equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes. The word equinox is derived from two Latin words – aequus (equal) and nox (night).

Which days are equinoxes?

The equinoxes happen in March (about March 21) and September (about September 23). These are the days when the Sun is exactly above the Equator, which makes day and night of equal length.

### Is the September equinox always on the same day?

The two equinoxes — which are the days on which day and night are nearly equal — occur roughly around the same time every year, but they don’t always fall on the same dates. In 2011, the September equinox — which is the beginning of autumn in the Northern Hemisphere and the beginning of spring in the Southern Hemisphere — fell on September 23.

### When do the northern and southern hemispheres experience the same equinoxes?

Chuseok. The equinoxes are the only time when both the Northern and Southern Hemisphere s experience roughly equal amounts of daytime and nighttime. On Earth, there are two equinoxes every year: one around March 21 and another around September 22. Sometimes, the equinoxes are nicknamed the “ vernal equinox ”…

Why do equinoxes happen on different days each year?

When do the equinoxes happen? Equinoxes don’t necessarily occur on the same day each year, rather they happen around or on March 20 and Sept. 23. These shifting dates are because an Earth year is not exactly 365 days: There is an extra quarter of a day (6 hours) that accumulates each year, causing the date of the equinox to shift.

How are day and night equal at the equinox?

For a single moment twice a year, both poles are equidistant from the sun; day and night are roughly equal in both hemispheres on the dates when this equinox occurs. When measured in sidereal time — time relative to the stars — the equinox happens at the same moment for everyone, but people experience it at different local times.
