How holidays are computed
Fixed-date holidays — New Year’s Day (Jan 1), Valentine’s Day (Feb 14), St. Patrick’s Day (Mar 17), Independence Day (Jul 4), Halloween (Oct 31), Christmas Day (Dec 25), and New Year’s Eve (Dec 31) — are straightforward.
Variable holidays require formulas:
| Holiday | Rule |
|---|---|
| Easter | Meeus/Jones/Butcher Gregorian algorithm |
| Mother’s Day | 2nd Sunday of May |
| Memorial Day | Last Monday of May |
| Father’s Day | 3rd Sunday of June |
| Labor Day | 1st Monday of September |
| Thanksgiving | 4th Thursday of November |
Worked example
Reference date: June 15, 2026
- Father’s Day (Jun 21) → 6 days
- Independence Day (Jul 4) → 19 days
- Labor Day (Sep 7) → 84 days
- Halloween (Oct 31) → 138 days
Notes
- All dates are computed locally in your browser — no server calls.
- Holidays that fall on the reference date show 0 (Today!).
- The calculator shows both the current year and, where needed, next year’s occurrence.
