British Summer Time (BST) starts on Sunday 30th March 2014. The clocks change at 1am, moving forward an hour from Greenwich Mean Time (GMT).
The effect is lighter evenings and darker mornings and is also known as Daylight Saving Time. Remember that throughout BST, astronomy software such as planetarium software and GoTo mounts may need to be configured to account for the clock change to accurately reflect the night sky. BST operates until Sunday 26th October when we will then revert back onto GMT.
