📅 Date Difference
Days, weeks and months between two dates
About this calculator
How many days between two dates? Enter a start and end date and the calculator returns the difference in days, weeks, months, and years — including or excluding the end date, your choice. It handles leap years correctly, can add or subtract a number of days from any date, and can also express the answer as total hours or minutes — useful for billing and project planning.
Tip: for contracts and deadlines, double-check whether the count is inclusive — "30 days from today" and "30 days including today" give different answers.
