About International Bluetooth Day
International Bluetooth Day arrives every September 28 to celebrate one of the quiet workhorses of modern technology. The short-range wireless standard connects billions of devices, from headphones and smartwatches to car stereos, medical sensors, and factory equipment, all without a cable in sight.
The name and logo honor tenth-century Danish King Harald Bluetooth, who united warring Danish tribes into a single kingdom. Engineers saw a parallel with the technology's goal of uniting the fragmented worlds of computers and mobile devices. The famous rune-inspired logo merges the king's initials, H and B, written in Nordic runes.
The day gives enthusiasts, engineers, and everyday users a chance to appreciate how far the standard has come since the Bluetooth Special Interest Group formed in 1998. From crackly audio streams to today's low-energy chips that run for months on a coin cell, Bluetooth's evolution mirrors the miniaturization of modern gadgets themselves.

History of International Bluetooth Day
Bluetooth began in the mid-1990s at Ericsson in Sweden, where researchers sought a cheap, low-power radio link to replace the tangled cables between devices. In 1998, Ericsson, IBM, Intel, Nokia, and Toshiba founded the Bluetooth Special Interest Group to govern the standard. The codename Bluetooth, borrowed from King Harald Gormsson, was meant to be temporary, but marketing never found anything better. The first consumer products shipped around 1999, version 2.0 brought faster data rates, 4.0 introduced the low-energy mode that powers wearables today, and version 5 extended range and broadcast capability. September 28 has been adopted by fans and industry groups as a day to recognize the standard's improbable journey from a cable-replacement experiment to a fixture in billions of devices.
