Days Between Dates Calculator
The exact number of days between two dates, plus weeks, weekdays, and a full breakdown.
How the days are counted
The count is exclusive of the start date and inclusive of the end date. Monday to Friday of the same week is 4 days, and a date to itself is 0. This matches how ages, deadlines and interest periods are normally counted. If you need both endpoints included, add 1.
Weekdays vs. business days
The weekday count excludes Saturdays and Sundays but knows nothing about public holidays, which vary by country and year. For contract deadlines, check the relevant holiday calendar on top of the weekday figure.
