National Billy Day is celebrated every year on February 25. Think of it like a mini-birthday for a first name: a day to appreciate the Billys you know (and the ones you’ve heard about).
It’s a fun excuse to spotlight the name’s charm and give a quick shoutout to every Billy who’s ever made you laugh, helped you out, or simply stood out.

Where does the Name Billy Come From
Billy is commonly used as a diminutive of Bill, with Bill itself being a classic short form of William.
William derives from Germanic elements meaning will or desire and helmet or protection often interpreted as “resolute protector.”
