Payday & Payroll Calendar

How to use this calculator

Choose a schedule year and frequency. Weekly, biweekly and monthly schedules use a known nominal payday; twice-monthly schedules use two day numbers. Enter the calendar-day lag from period end to nominal payday, processing workdays, workweek and closures.

Schedules are selected by nominal payday year, even when adjustment moves a payment into the prior or next year. Period end is nominal payday minus your lag; period start is the prior period end plus one day. Processing cutoff counts backward from adjusted payday through your work calendar. Monthly day 31 clamps independently to each month end. The year range is 1901–2099 to leave room for cross-year adjustments.

A worked example

With a biweekly anchor of January 1, 2027, that year contains 27 nominal paydays. A seven-day lag gives a first period end of December 25, 2026. If January 1 is excluded and the rule is previous working day, the first payment moves to December 31.

Are bank holidays and employer payroll rules automatic?

No. Enter the relevant closures, lag and adjustment rule. This is a planning calendar, not a promise of when funds will arrive. Repeated adjusted dates remain separate nominal pay periods.
