Quick notes
Use this for countdowns, trip lengths, project timelines, invoice windows, and planning gaps.
Business day count is useful when weekends should not be treated like working days.
Calendar difference keeps months and days human-readable instead of flattening everything into one number.
You can choose whether the ending date itself counts in the result.

Why people come back
Date gaps keep showing up in travel plans, school schedules, invoices, subscriptions, and project planning.
Business-day count makes this more useful than a basic day counter.
Include-end-date mode helps when you need the “human” version of a range, not just the technical difference.
Strong first-use cases
Counting how many days are left before a trip, event, or deadline.
Checking the span of a booking, rental, or contract window.
Comparing workday count for a project schedule or invoice cycle.
Practical notes
Total-day view is best when you need a simple exact count.
Calendar difference is better when you want something human-readable like “2 months and 3 days”.
Business-day count ignores weekends, which makes it much more useful for real-world planning.
