We're sorry to be the bearer of bad news, but it's official - summer is sadly starting to come to an end.
Soon enough we'll be digging our winter coats out from the back of the wardrobe and beginning to hear the crunch of leaves underfoot as a new season begins to draw in.
But now that we have officially entered September, many will no doubt be starting to wonder how many weeks we have got until autumn officially begins.
Technically summer ends with the arrival of the Autumn Equinox, when the sun cross the Earth's equator from north to south.
As well as signalling the start of the new season, it also has a spiritual meaning for pagans as it's when day and night are most equal and the earth balanced.
So as we fast approach the new season, here's all you need to know about the 2019 Autumn Equinox.
What is the Autumn Equinox?
An equinox is a phenomenon which only happens twice a year - once during spring and once again in the autumn.
It happens when the sun positions itself exactly above the equator between the Northern and Southern Hemisphere.
For those in the Northern Hemisphere, the Autumn Equinox marks the beginning of autumn and for those in the southern it marks the beginning of spring.
Once the equinox hits in the autumn the nights become longer than the day, while the opposite happens after the Spring Equinox.
The term "equinox" stems from the Latin word "equi," meaning equal and "nox," meaning night.
When is the Autumn Equinox?
This year, the Autumn Equinox takes place on September 23 at 8.50am BST.
The Autumn Equinox always falls on one of three days towards the end of September.
The date varies because of the difference between how the Gregorian calendar calculates a year (365 days) and the time it takes for the Earth to complete its orbit around the sun, which is 365.25 days.
Because of the difference in the days, it means each September the equinox occurs around six hours earlier than the previous year.
How is the Autumn Equinox celebrated?
People have been commemorating the Autumn Equinox for centuries.
Ancient peoples such as the Druids in England and the Maya in Central America see it as a marker of the harvest season.
During the Autumn Equinox, neo-druids gather at Stonehenge to perform rituals.
In Mexico, crowds flock to the pyramid at Chichen Itza on the Yucatan Peninsula. A serpent-headed statue is placed at the foot of the pyramid and as the sun sets, the sunlight and the shadow show the body of the serpent joining with the head.
