IL HB3790

Designates Lunar New Year as an official state holiday in Illinois, observed on the second new moon following the winter solstice (or third new moon if an intercalary month intervenes), with observance moving to Monday when falling on a weekend

Amends the School Code to explicitly authorize school boards to grant Lunar New Year as a special holiday for schools

Maintains Lunar New Year as a special holiday rather than a legal school holiday, meaning school employees would not automatically have the day off but districts have discretion to close

Adds Section 57 to the State Commemorative Dates Act to establish the formal definition and recognition of Lunar New Year throughout the state
