Easter Sunday falls on the first Sunday after the full moon following the spring equinox on 21st March. This unusual calculation, which uses a mixture of solar and lunar calendars, means that the day itself can occur anytime in a period of over a month - between 22nd March and 25th April. The next time it will fall this late will be in 2038 and you will have an even longer wait for a very early Easter. It will not take place on 22nd March until 2285.

Visitors to London often want to go inside Buckingham Palace when they come there and see the Changing of the Guard ceremony. Yet, while Windsor Castle is open to the public throughout the year, the chief royal residence of London is only open for ten weeks between mid-July and September every year when the royal family are at Balmoral Castle. The tradition of spending the late summer and early autumn in the Scottish Highlands was established by Queen Victoria and Prince Albert and has continued since her reign.
