Why Use This Tool?
Project deadlines, contract terms, visa windows, rental periods — half of office life is counting days between two dates. This calculator gives you the total in one click, and then goes further: weeks and leftover days, a proper years-months-days breakdown, and business days that skip weekends.
Dates in either order work — the tool handles reversed input gracefully. Tick 'include the end day' when you're counting something like a hotel stay or a notice period where both endpoints count.
How It Works
- Pick a start date and an end date.
- Optionally include the end day in the count.
- Read total days, weeks, the calendar breakdown, and business days.
Frequently Asked Questions
How do I calculate days between two dates?
Pick both dates above and click calculate — you get total days instantly, and the count is exact across leap years and month lengths.
How are months between dates counted?
Calendar-aware: from Jan 31 to Mar 1 counts as one month plus one day, not a flat 30-day guess. The breakdown shows years, months, and leftover days separately.
What are business days?
Monday-through-Friday days in the range, excluding weekends. Holidays vary by country, so add those on top for your region.
Tips & Things to Watch
- Use 'include the end day' for stays, notice periods, and warranties.
- Business days skip weekends but not public holidays — add those manually.
- Reversed dates are fine; the tool sorts them for you.
