What this calculates
This days between dates calculator finds the exact number of calendar days between any two dates, plus the same interval expressed in weeks, months, and years. By default the end date is counted as a full day. Turn the toggle off to exclude it.
Common uses
- Working out how many days until a holiday, event, or deadline.
- Counting days since a personal milestone: a move, a new job, or an anniversary.
- Hotel and rental stays where the checkout day is inclusive.
- Tracking notice periods and project durations.
How it works
Both dates are treated as midnight UTC, so daylight-saving changes and time zones never shift the result. Months and years vary in length, so the breakdown converts the day count into average months (30.44 days) and years (365.25 days), rounded to one decimal place.
