From the Bureau link I posted above: "Biweekly is the most common length of pay period, with 36.5 percent of U.S. private businesses paying their employees every 2 weeks."
It seems the difference between biweekly (using this definition) and bimonthly is that occasionally you might get paid three times in a month, since the weeks don't align with the months.
That's not the definition everyone uses :)
