Ever wondered why the Easter date changes each year?
Sometimes the Easter date is in early April. Sometimes it’s in late April. There are other times the Easter date changes to late March.
It’s a great time of year. Children get exited for the arrival of the Easter Bunny. There’s often lots of chocolate and you might even do some egg shell painting at home.
There are traditions of fish for Easter Friday, Easter egg hunts on Sunday and special times to spend with family.
So why does the Easter date change each year?
Believe it or not, the reason the Easter date changes every year has a lot to do with astronomy!
It’s got nothing to do with a decision made churches, public holiday makers or governments.
Quite simply, Easter Sunday is deemed to be the first Sunday after the full Moon, following the March Equinox. Just so you now, the March Equinox is always on or around 22nd March each year.
That raises another astronomical question! What is the March Equinox?
Easter date 2021
It’s a bit of a calculation and here it is for the Easter date 2021:
In 2021, the March Equinox was on 20th March. The full Moon after this date is on the 29th of March and therefore Easter Sunday is the following Sunday which is the 4th of April 2021!
Now you’ll be able to impress friends and relatives with your knowledge of why the Easter date changes each year! Or you’ll be able to predict when the Easter date will be for many years to come. All you need to know are the dates of the March Equinox and a full Moon chart.
Speaking of the Easter Bunny...Here's one for the kids!
Did you know that you can make the shape of a rabbit on the Moon? This is a fun activity for children to try. Check out the latest Stargazing Forecast to find out when the next Full Moon rises. Then head outside to wait and watch.
First use the image above to find the rabbit.
Then imagine what it was like to travel in a spacecraft to land on the Moon in 1969.
Apollo 11, the first spacecraft to take humans to the Moon, landed in the Sea of Tranquillity, which is the large grey area that makes up the head of the rabbit. Apollo 11 landed towards the bottom of the rabbit’s left ear. That’s the rabbit ear on the right as we see it from Earth!
ready for some stargazing this easter?
It’s something you can do from home, it’s free and you’ll be surprised at what you’ll discover.
