How it works
Weekly paydays are 7 days apart and biweekly paydays 14 days apart, counted from your first payday. Semimonthly paydays are the 15th and the last day of each month. Monthly paydays keep the same day of the month, or the last day in shorter months.
Worked examples
- Biweekly from Friday 1 January 2027: 27 paydays in 2027, with three in January, July and December.
- Semimonthly from 15 January 2028: 15 and 31 January, 15 and 29 February (a leap year), 15 and 31 March.
- Monthly on the 31st: 31 January, 28 February, 31 March, 30 April.
Common questions
Why do some years have 27 biweekly paydays?
A year has 52 weeks and one or two extra days. Every 11 years or so those days add up to an extra two-week period, so the year has 27 paydays instead of 26.
Is biweekly the same as semimonthly?
No. Biweekly is every two weeks, 26 or 27 times a year, always on the same weekday. Semimonthly is twice a month on fixed dates, 24 times a year, so each check is a little larger.
What happens when payday is on a holiday?
The calendar marks weekends and US federal holidays. Many employers then pay the business day before, but the date is set by your employer's policy and state law.
