What is April Fools' Day?
April Fools' Day is 1 April, a day for hoaxes with a history running back at least to the sixteenth century and no clear single origin. A common convention in Britain is that pranks are only fair before noon. It is a normal working day everywhere, which is exactly why so much of the day happens at work and online. The countdown targets midnight at the start of 1 April in your own zone, which gives you the morning window in full.
The next one falls on Thursday, 1 April 2027, and this page counts down to the midnight that starts it in whatever time zone your browser reports. For a date of your own, the deadline countdown takes any target and tracks progress against it.
