When will the next year with 27 pay periods in government be?

In the U.S. federal government, pay periods are typically biweekly, leading to 26 pay periods in a year. However, when a year has 27 pay periods, it typically occurs every 11 years. The next occurrence of a year with 27 pay periods will be in 2024, as the last was in 2013. This is due to the timing of the first paycheck of the year falling on the last day of the previous calendar year.
