Founded by entrepreneur, computer historian and member of the
Unicode Emoji steering committee Jeremy Burge in 2014—a year after starting the reference site
Emojipedia—today has been set aside as World Emoji Day.

The date was chosen in deference to the default date already displayed in the calendar application software of Apple systems (iCal) between 2002 and 2007, itself in reference to the debut of the cross-platform scheduling and sychronising assistant at the Mac World Expo that summer. Though now apps are dynamic and display the actual date, this design artefact is retained and reflected in modern parlance and used in most operating system
emoji vernacular. How do you plan to celebrate?
