Last updated this release
Public holidays vary widely and change more often than most people expect. This policy explains how DateAndTimePro.com presents holidays and what users should keep in mind.
Educational use
Holiday information on DateAndTimePro.com is educational. It is intended to help users plan and learn, not to replace official governmental, employer, or institutional holiday calendars.
Why holidays vary
- Holidays vary by country, state, province, and municipality.
- Many holidays are observed differently by private employers, schools, financial markets, and government offices.
- Some holidays are based on lunar or religious calendars and shift each year.
- Substitute or 'observed' days are sometimes declared when a fixed-date holiday falls on a weekend.
How we present holidays
- Holiday pages and countdowns identify the most widely recognized observance dates.
- Where regional variation is significant, we note it on the page.
- Where a holiday's date is calculated (for example, lunar-based holidays), our calculation is documented and may differ from purely traditional observance.
Verify with authoritative sources
For payroll, banking, travel, government filings, or employer-specific schedules, users should verify holidays against the relevant authoritative source (for example, a national government's official holiday calendar or an employer's HR policy).
