Date Calculator
Calculate date differences or add and subtract days from any date.
How the Date Calculator Works
The Date Calculator helps you find the exact difference between two dates or compute a new date by adding or subtracting days. It calculates complete years, months, and remaining days, as well as total days, weeks, and business days (excluding weekends).
In Add/Subtract mode, simply choose a starting date and specify how many days to add or subtract. The calculator handles month boundaries, leap years, and varying month lengths automatically.
