The summer solstice is an important event in the calendar as it is the longest day of the year.
Countries in the Northern Hemisphere will mark the summer solstice between Sunday, June 20, 2021 and Tuesday, June 22, 2021.
The event is considered important because it heralds the start of summer and coincides with the day in which we see the most hours of daylight.
For the UK, the event will fall on Monday, June 21, 2021 - when people will be able to enjoy around 16 hours and 38 minutes of daylight.
After that, each day will incrementally have shorter amounts of daylight as we approach the winter months.
The autumn equinox in September signals the end of summer, as day and night become almost equal on this day.
And daylight will continue to lessen until the winter solstice, which typically takes place in December, marking the shortest day of the year.
What is the summer solstice?
The summer solstice in the Northern Hemisphere is an event where the North Pole tilts as far as it can towards the sun.
Because of this, there is more daylight on this day than on any other day throughout the year.
Events to mark the occasion take place annually in Stonehenge, Wiltshire, where - usually - large crowds of people gather.
Can people gather at Stonehenge to mark the summer solstice?
Not this year, unfortunately.
English Heritage had been hoping to allow people to gather for the summer solstice if coronavirus restrictions were lifted on June 21.
But with the Government delaying the further easing of rules by another four weeks, organisers have had to cancel.
"In previous years numbers attending the Summer Solstice at Stonehenge have swelled through the night to anything from 7,000 to 30,000 plus people, far in excess of the 4,000 currently permitted at outdoor gatherings during the now continuing Step 3 of the roadmap," English Heritage has said.
It means the general public will not be allowed to watch the event from Stonehenge itself.
However, small groups from the pagan and druid community, who share a love of nature, will be allowed to gather on days around the summer solstice to continue commemorating the hugely important event.
If you’re not one of them and haven’t pre-booked, there will always be an online live stream instead.
How do I watch the summer solstice live stream?
The summer solstice is an important event for lots of people, and many will not want to miss marking the occasion.
English Heritage will, therefore, make a live stream of the event available via on its social media channels, similar to last year's arrangements.
This should only be a temporary measure, as it’s hoped when the next summer solstice happens, coronavirus restrictions will be lifted, allowing everyone to gather at Stonehenge once again.
