Paycheck Date Calculator

Biweekly vs. semimonthly — the mix-up that trips people up

These two get confused constantly, but they're not the same schedule. Biweekly means every 2 weeks, always on the same weekday, producing 26 paychecks a year (occasionally 27) with two 3-paycheck months annually. Semimonthly means twice a month on fixed calendar days — most commonly the 1st and 15th, or the 15th and last day of the month — producing exactly 24 paychecks a year, always two per month, but on a weekday that shifts around.

Weekend and holiday adjustments aren't included

This tool projects the raw schedule forward; it doesn't know your employer's specific rule for what happens when a payday lands on a weekend or bank holiday (most shift it to the preceding business day, some to the following one). Treat dates that land on a Saturday or Sunday as needing that adjustment.
