Frequently asked questions
Which holidays are included?▾
Common US federal holidays (New Year's, MLK, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, Christmas) for the surrounding years.
Are observed holidays handled correctly?▾
Mostly — the embedded list uses the actual fixed/observed dates as published. For region-specific or company holidays, do a manual adjustment.
Can I subtract instead of add?▾
Yes — switch direction to "subtract" and the calculator counts backwards while still skipping weekends and holidays if selected.
