* Spring, Summer and Easter all at the same time?
British Summer Time this year started on the 31st March when the clocks went forward one hour. Last year it was on the 25th March because it's always on the last Sunday in March.
Easter this year is later than 2018 and on its latest date for 8 years. Good Friday is on 19th April and Easter Monday is on the 22nd.
The reason it changes is that Easter Sunday falls on the first Sunday after the first full moon following the spring equinox...and that changes every year because the solar calendar we use doesn't match up with our 7 day week.
So we've got Springtime, Easter and British Summer time all at once...it just changes every year.
