How is semi -monthly different than bi-weekly?

Semi-monthly refers to a payment schedule that occurs twice a month, typically on set dates such as the 1st and 15th. In contrast, bi-weekly means payments are made every two weeks, resulting in 26 pay periods per year instead of 24. This difference can lead to variations in total earnings and pay dates, especially in months where a semi-monthly pay period may not align with the bi-weekly schedule.
