Days Between Dates
Enter a start and end date to get the total days between them, broken down into weeks and business days.
Overview
Counting days between two dates by hand means tracking varying month lengths and leap years, and "how many days" often really means "how many working days," which needs weekends excluded too. This tool returns all three views — total calendar days, whole weeks plus remainder, and business days (Monday–Friday) — from a single pair of dates.

Tips & Best Practices
- The business day count excludes Saturdays and Sundays only — it doesn't account for public holidays, since those vary by country and region.
Frequently Asked Questions
No. The calculation runs entirely in your browser using JavaScript.
The total day count is the difference between the two dates — the end date itself is the boundary, not an extra counted day, matching how "days between" is normally understood.
Either order works — the tool always returns a positive count regardless of which date you enter first.
