National Levi Day circulates on observance calendars each 23 August. A controlled search finds no Federal Register footprint for the name, and no founder, establishing organisation, proclamation or first observance has been documented.
What the Levites got instead
Levi's descendants became the Levites, the tribe that served the sanctuary. Numbers 18 gives them no territorial share at all and assigns them tithes instead.
The arrangement outlived the Temple it was written for. Levites remain exempt from pidyon haben, the ceremony that redeems a firstborn son.
