What does is mean to be paid biweekly?

"Getting paid ""bi-weekly"" means that one receives a paycheck every two weeks. Given that some companies pay their bi-weekly employees on the 1st and 15th of every month, however, the employee is not always getting a paycheck every two weeks (as the name implies), but rather simply twice a month. In a 31-day month, the employee will wait 16 days for a paycheck."
