The UK Parliament established British Summer Time through the Summer Time Act 1916, receiving royal assent on May 17, 1916, as a wartime measure to conserve energy during World War I by advancing clocks one hour. It was first proposed seriously by William Willett in 1907.
Get ready to spring forward and embrace sunlight like never before as "British Summer Time Begins" commences on March 31! It's an exciting time when the clocks go forward by one hour, and the UK officially bids farewell to the grey skies of winter and welcomes the longer, sun-soaked days of summer. The concept of daylight saving, of which British Summer Time is a part, finds its roots way back in 1784, championed first by Benjamin Franklin who believed it could help people to make better use of daylight and save on candles! Now, it's a herald of the warmer season to come, when flowers bloom, adventures beckon, and smiles shine brighter. So let's not wait, embrace the joy and anticipation that this day brings along!

WHY THIS DAY MATTERS
British Summer Time serves as a commencement for planning new adventures, starting gardening projects, or executing a summer bucket list. It cultivates anticipation, fostering growth and enjoyment for the full beauty of summer when it fully blooms.
The main perk of British Summer Time is the longer hours of daylight. We love the fact that we can leave work and still have several hours of sunshine left, which is great for outdoor activities, social gatherings, or simply winding down the day with a pleasant evening walk.
British Summer Time Brings fun and innovative ways to celebrate, like the sunrise gathering or summer-themed parties. These unique events infuse excitement into the upcoming season and provide a joyful break from routines.
