Holiday Date Calculator

A Holiday Date Calculator determines the exact dates when major holidays occur in any given year. Whether you're planning events, organizing work schedules, or coordinating across regions, knowing the precise date of Easter, Thanksgiving, Christmas, and other observances is essential. This tool uses mathematical formulas—particularly the Meeus/Jones/Butcher algorithm—to compute movable holidays like Easter Sunday and all related holidays that depend on it.

Simply enter a year between 1900 and 2100, then click Calculate to see a complete list of major holidays for that year. The results display each holiday's date, the day of the week it falls on, and whether it has a fixed date or varies annually. You can also see how many days remain until each upcoming holiday, and copy the entire list to your clipboard for easy sharing or pasting into calendars, spreadsheets, or planning documents.

This calculator supports common holidays observed across the United States and internationally—including New Year's Day, Valentine's Day, Good Friday, Easter, Mother's Day, Father's Day, Independence Day, Labor Day, Thanksgiving, Christmas, and New Year's Eve. It's invaluable for event planners, business managers, educators, and anyone who needs to coordinate schedules across multiple holidays and time zones.
