How do I calculate days between two dates?

Enter your start date and end date in this calculator and it will instantly show the number of calendar days between them, along with the equivalent in weeks, months, hours, and minutes. The calculation accounts for different month lengths and leap years automatically.

Does this include the start and end dates?

By default, the calculator counts from the day after the start date to the end date (exclusive of start, inclusive of end). This is the standard method for counting elapsed days. If you need to include both the start and end dates, add 1 to the result.
