How Many Weeks in a Year for Payroll — and Does the 27th Period Actually Happen?

I've been reading conflicting things online about how many weeks in a year for payroll purposes. I understand it's technically 52 weeks, but some sources mention 52.18 weeks when you account for the extra day (or two in a leap year). Does that fractional week ever actually create a 27th pay period for bi weekly payroll, and if so, how should payroll managers handle salaried employees in that scenario without overpaying them? This seems like a significant issue that doesn't get enough attention in payroll training materials.
 
Yes, payroll bi-weekly results in 27th pay period after every 11-12 years since there are 52 weeks and one (or two) days in a year. Managers can either get the annual pay of the salaried employees divided by 27 or keep the regular number of 26 periods which means that they offer the employees a bonus year.
 
A year has 52 weeks (plus 1–2 extra days). In payroll, biweekly schedules usually have 26 periods, but a 27th pay period can occur roughly every 11 years due to calendar alignment.
 
I've come across this issue before and it can be a bit confusing, especially when you're trying to account for that extra day or two in a leap year. In reality, the 27th pay period does happen, but it's not as straightforward as it sounds. Payroll managers typically handle this by either paying employees for 26 pay periods and then adjusting the last pay period to account for the extra days, or by paying employees for 27 pay periods but reducing the amount of the last pay period to avoid overpaying them. It's usually best to review your payroll software and consult with a payroll expert to determine the best approach for your specific situation.
