IL HB1157

Defines "the celebration of Passover" as the eight-day period beginning on the 15th day of the Hebrew lunisolar month of Nisan for purposes of election postponement provisions

Applies this standardized definition across four Illinois statutes: the Election Code, Township Code, Revised Cities and Villages Act of 1941, and School Code

Consolidated elections that conflict with Passover must be postponed to the first Tuesday following the last day of Passover

Township annual meetings may be postponed when conflicting with Passover (or Ramadan), moving to the first Tuesday after the holiday ends

Chicago mayoral runoff elections and school board elections must also be rescheduled when conflicting with the newly-defined Passover period
