Date Difference Calculator
Find exactly how much time has passed between two dates. This tool provides total days, a breakdown of years/months/days, and an accurate count of working days.
How do I calculate the difference between two dates?
Simply enter the start and end dates. The calculator will provide the total number of days, weeks, months, and years, as well as an accurate count of business days.
What are business days?
Business days are the working days of the week, typically Monday through Friday. This calculator excludes Saturdays and Sundays from the "Business Days" result.
Does this calculator account for leap years?
Yes! The tool uses full calendar logic to account for leap years and the varying number of days in each month for maximum precision.
Should I include the end day?
In many business contracts, the end day is included in the count (e.g., "30 days from now"). Selecting "Yes" will add 1 day to all result fields.
