<P> BST begins at 01: 00 GMT on the last Sunday of March and ends at 01: 00 GMT (02: 00 BST) on the last Sunday of October . Since 22 October 1995, the starting and finishing times of daylight saving time across the European Union have been aligned--for instance Central European Summer Time begins and ends on the same Sundays at exactly the same time (that is, 02: 00 CET, which is 01: 00 GMT). Between 1972 and 1995, BST began and ended at 02: 00 GMT on the third Sunday in March (or second Sunday when Easter fell on the third) and fourth Sunday in October . </P> <P> The following table lists recent - past and near - future start and end dates of British Summer Time: </P> <Table> <Tr> <Th> Year </Th> <Th> Start </Th> <Th> End </Th> </Tr> <Tr> <Td> 2015 </Td> <Td> 29 March </Td> <Td> 25 October </Td> </Tr> <Tr> <Td> 2016 </Td> <Td> 27 March </Td> <Td> 30 October </Td> </Tr> <Tr> <Td> 2017 </Td> <Td> 26 March </Td> <Td> 29 October </Td> </Tr> <Tr> <Td> 2018 </Td> <Td> 25 March </Td> <Td> 28 October </Td> </Tr> <Tr> <Td> 2019 </Td> <Td> 31 March </Td> <Td> 27 October </Td> </Tr> <Tr> <Td> 2020 </Td> <Td> 29 March </Td> <Td> 25 October </Td> </Tr> <Tr> <Td> 2021 </Td> <Td> 28 March </Td> <Td> 31 October </Td> </Tr> </Table> <Tr> <Th> Year </Th> <Th> Start </Th> <Th> End </Th> </Tr>
