Date Difference Calculator

To calculate the duration between two dates, choose the start date and the end date using the date pickers. The results will instantly calculate the difference in years, months, and days, as well as alternative formats like total days, business days (excluding Saturday and Sunday), weeks, and hours.

You can optionally select to include the end date in the calculations. This is useful for project plans and billing cycles where both the start and end days are considered active days of work or service.
