Date difference calculator
Measure the exact span between two dates in days, weeks, months, years, hours, and minutes.
What This Date Difference Tool Is Best For

📅 Days Between Dates
Precise calculation of total calendar days between any two dates.
📆 Weeks & Months
Break down the difference into years, months, weeks, and remaining days.
⏱️ Hours & Minutes
For short periods, see the difference in total hours and minutes.
What makes it different
Unlike the business-days calculator, this page counts the full calendar gap. It is meant for personal timelines, milestone tracking, and general date math where weekends and holidays should still be included in the result.
The count uses calendar dates, not business hours. A Friday-to-Monday span includes the weekend. Leap days are included when they fall between the two dates. If you need SLA or payroll windows, use the business-days calculator with a country holiday list instead.
End-before-start is a valid input: the tool reports a negative or swapped span depending on the fields. Time-zone midnight edges can move “today” for travelers; pick explicit calendar dates rather than relying on the device clock when the result is contractual.
