World Emoji Day is an annual unofficial holiday occurring on 17 July, intended to celebrate emoji; in the years since the earliest observance, it has become a popular date to make product or other announcements and releases relating to emoji. The date originally referred to the day Apple premiered its iCal calendar application in 2002. The day, July 17, was displayed on the Apple Color Emoji version of the calendar emoji (?) as an Easter egg. World Emoji Day is "the brainchild of Jeremy Burge" according to CNBC which stated that the founder of Emojipedia created it in 2014.
