Semi-Monthly: Occurring Twice Each Month

An in-depth exploration of the term 'Semi-Monthly', its applications, differences with other frequencies, and detailed examples.

Semi-monthly refers to an event or action that occurs twice each calendar month. Common examples include payroll processing, which many organizations execute on a semi-monthly schedule, typically on the 15th and the last day of the month.

Definitions and Formulas§

In a semi-monthly system, there are usually two equal intervals within a month. The exact dates can vary but generally fall either in the middle and end of the month or at other evenly spaced intervals.

Mathematically, if $n$ represents the total occurrences in a month:

$$n = 2$$

Differences Between Pay Frequencies§

Semi-monthly vs. Bi-Weekly:

• Semi-Monthly: Occurs twice a month, leading to 24 pay periods in a year.
