Enter a start and end date to count the days, weeks, and business days between them.
How to Use the Day Counter
Start and end date are the only two fields; business days count separately from calendar days, since weekends are excluded from one total but not the other.
Two dates, and a decision this Day Counter leaves up to you: does the end date count or not? "March 1 to March 5" is 4 days if you're measuring the gap between them, or 5 if you're counting how many calendar days the span touches — both are legitimate answers to slightly different questions, which is why the toggle exists instead of picking one silently.
Business days counts Monday through Friday only, with no adjustment for public holidays — those vary too much by country and region to bake into a single global default.
