A date calculator computes the exact number of calendar days, weeks, months, and working (business) days between any two dates. It can also add or subtract a specified number of days, months, or years from any starting date to find the resulting target date.
This tool is essential for project planning, legal deadlines, pregnancy tracking, countdown timers, visa validity calculations, and any scenario where precise date arithmetic is needed. All calculations account for leap years and variable month lengths automatically.
Follow these simple steps to achieve perfect results in seconds.
Select 'Days Between Dates' to find the difference between two dates, or 'Add/Subtract Days' to calculate a target date from a starting point.
Pick your start and end dates from the calendar picker, or type them directly. Toggle 'Include Business Days Only' to exclude weekends.
See the exact count of calendar days, working days, weeks, and months. Results include leap year handling and are displayed instantly.
