About Free Date Calculator
Free Date Calculator helps you answer everyday date questions in seconds — how many days between, business days vs. workdays, days since, days until, and more. We focus on clear wording, accurate math, and quick results that match real-life rules. Updated 2025.
Why we built it
Counting days should be simple. But weekends, holidays, and “inclusive vs exclusive” rules make it confusing. We built a tool that speaks human, handles the edge cases, and shows the result in a way you can share and trust.
- Clarity: plain-English labels and examples.
- Accuracy: correct day math, leap years handled, clean business-day logic.
- Speed: one page, simple options, instant results.
How it works (in plain English)
- Inclusive vs Exclusive: Inclusive counts both the start and end dates; Exclusive counts only the days between.
- Workdays only: Removes Saturdays and Sundays.
- Business days: Removes weekends and U.S. federal holidays (with observed dates).
- Weeks + days view: We also show a quick “weeks + days” line for planning.
Tip: If two people are off by one day, they’re using different modes. Agree on Inclusive or Exclusive first.
