About This Site

Pay Period Calendar 2027 exists because most payday calendars online get the holiday edge cases wrong.

What makes this calendar different

Every date on this site is computed by a single open calculation engine, unit-tested against the official source pages (GSA payroll calendar, OPM holiday schedule, Federal Reserve K.8 settlement holidays, DFAS pay schedules, SSA Pub. 05-10031 — all checked 2026-11-08).

Data sources

Official-date pages (federal, military, Social Security, bank holidays) render data transcribed from the linked official pages, each with its source URL and check date. Computed calendars (weekly, biweekly, semi-monthly, monthly, any anchor) are generated live by the engine.

Disclaimers

This site is not affiliated with any government agency. Dates are for planning; always confirm with your employer or payroll provider. Feedback and corrections: contact@pay-period-calendar-2027.example.com.
