Why biweekly pay in Illinois means two "extra" paychecks a year

Biweekly pay runs on a 26-period year (every 2 weeks), not a 24-period year like semi-monthly pay — the two are often confused but produce different check sizes for the same salary. On a $75,000 salary in Illinois, this engine estimates $2,231.72 net every two weeks under biweekly pay, versus $2,417.70 net under semi-monthly pay for the identical annual amount — each biweekly check is smaller because there are two more of them.

Because 52 weeks don't divide evenly into 26 two-week periods with calendar-month boundaries, two months of the year get a third paycheck instead of the usual two — a real budgeting quirk semi-monthly and monthly pay schedules don't have, since those are locked to fixed calendar dates rather than a rolling two-week cycle.
