Date Calculator

Calculate days between dates, add or subtract days

How to use the Date Calculator

Choose between three modes: 'Days Between' calculates the exact duration between two dates including total days, weeks, business days, and weekends. 'Add Days' finds a future date by adding a specific number of days to your start date. 'Subtract Days' finds a past date by subtracting days. Business days exclude weekends (Saturday and Sunday). All calculations account for leap years and varying month lengths.
