The group, led by the National Trust, English Heritage, the Heritage Lottery Fund and the Historic Houses Association, is hoping to persuade people to write a diary for Tuesday, 17 October, and then upload an electronic version to historymatters.org.uk.
The exercise in mass blogging will aim to highlight the relevance of history. National Trust comms director Ivo Dawnay said it would also show that the National Trust and the heritage sector are embracing modern communication techniques.
‘We are hoping this is going to be the world's biggest blog,' said Dawnay. ‘The aim is to create a snapshot of 21st-century life on an ordinary Tuesday. Although the information may seem very ordinary, it will become valuable to future social historians.'
The coalition is hoping to collect tens of thousands of entries until the end of this month.
Although teachers will be targeted, the group is looking for diversity and will be targeting print and broadcast consumer media.
Celebrities including TV historian David Starkey are helping to promote the campaign.
