No founder, organisation, or establishing announcement has been documented for National Jonathan Day, and no source explains why it falls on October 7. What can be traced is only its circulation, on third-party holiday listings and in individual social posts.
A name that arrived late in English
For an old name, Jonathan is a recent arrival in English. Behind the Name puts it plainly: it did not become common until after the Protestant Reformation.
The early bearer Behind the Name picks out is a satirist. Jonathan Swift, the Anglo-Irish writer who lived from 1667 to 1745, wrote Gulliver's Travels.
