You can put this solution on YOUR website! Biweekly means every 2 weeks.
Two weeks is 14 days, and there are 365 or 366 days in a year. <---> <--->
So, Leona will get at least biweekly paychecks in a year.
However, after the first paycheck received in a year,
Leona will be getting another paycheck.
That could happen within the same 365-day or 366-day calendar year,
and that last paycheck could be the 27th paycheck she receives in that calendar year.
