When British Summer Time begins on Sunday, we all turn our clocks forward by an hour to save daylight.
The worst that can happen is we’ll forget and arrive late for work or school on Monday. But, on the upside, there are a whole host of activities and events planned to help you recover your lost hour this weekend.
The Lost Hour celebrations imagines a scenario where we all find a spare hour and gives us a plethora of time and space-themes weird, wonderful, magical and fantastical ideas for what we could do with this limbo time.
Aimed at young people, the citywide free events take place on Saturday and include a Time Machine at Gunwharf Quays.
Its crew will be inviting people in through the wardrobe entrance to an unusual and scientific structure where they will be encouraged to join in games, dancing, singing and scientific tests on the waterfront by All Bar One from 3pm until 8.30pm.
There will also be a special lighting display at the Spinnaker Tower to mark the mystical events from 5.30pm to 11pm. The lights will be transmitting messages in morse code. To find out more, visit the tower or Aspex Gallery.
Meanwhile, over at the New Theatre Royal, there is an Easter and space-themed Eggstraordinary Eggsperiment with workshops throughout the day for different age groups. To book, call (023) 9264 9000.
At Groundlings Theatre you can adventure into the jungle. While, at John Pounds Corner there’s a murder mystery with Sherlock Holmes.
At the D-Day Museum there will be special late-opening and screenings of archived public instruction films, special family trails and poetry workshops.
And, at the big screen in Guildhall Square, there will be screenings of locally produced space-themed films, art and animations.
The Square Tower and Central Library will offer all sorts of creative responses to the theme with performances and exhibitions.
There are space-themed craft workshops and Cosmic Crazy Golf at the City Museum.
If you think you can cram more than one event into your Lost Hour (or you fancy losing track of time completely and spending the whole day in the lost realm), you can create a Planet Portsmouth Passport at the Central Library and collect stamps at every Lost Hour venue you visit.
The memento will give you something to look back at and remember your Lost Hour adventures.
