Example

An employee with a salary of 24,000 is planned to receive a raise on February 10. Using the Even spread method for salaried employees (i.e., the annual salary is evenly distributed throughout the year), the monthly spread factor is 1 and the total of the spread factors is 12. After the raise, the employee will have a salary of 28,800.

January Salary: 24,000 * 1/12 = 2,000 (event not in this month)

February Salary: ( 2,000 * 9/28) + ( 2,400 * 19/28) = 2,271 (event in middle of the month)

March Salary: 28,800 * 1/12 = 2,400 (event not in this month)
