How the schedule is calculated
For weekly and biweekly schedules, the known start date anchors consecutive 7- or 14-day periods. Semimonthly periods run from the 1st through the 15th and from the 16th through the last day of the month. Monthly periods follow calendar months.
The difference between the known period end and known payday is reused as the payday lag. If you choose a weekend rule, only Saturdays and Sundays are adjusted; employer holidays are not inferred.
Three-paycheck months
A biweekly schedule normally produces two paydays per month, with two months in many 26-paycheck years containing a third. ClockSlate flags months with at least three generated biweekly paydays. Weekly schedules similarly flag five-paycheck months.
Frequently asked questions
What is the difference between biweekly and semimonthly?
Biweekly means every 14 days and usually creates 26 paydays per year. Semimonthly means two defined periods per calendar month and normally creates 24 paydays per year.
Can the payday be before the period ends?
Yes. The calculator preserves the relative timing supplied by the known period and payday, including a negative lag.
Does the weekend rule include bank holidays?
No. It moves only Saturday or Sunday dates. Holiday handling varies by employer and payroll provider.
