Find out exactly how many days are between any two dates.
Frequently Asked Questions
Does the calculator include the start and end date?
The count is the number of days between the two dates, not including the start date but including the end date. To count both dates (e.g. how many days an event spans), add 1 to the result.
How do I calculate how many days until an event?
Set the start date to today using the button below the first field, then set the end date to your event. The result shows exactly how many days remain.
How many days are in a year?
A standard year has 365 days. A leap year has 366. This calculator accounts for leap years automatically when counting across year boundaries.
Can I calculate working days between two dates?
Yes — toggle "Weekdays only" above the result to switch to a weekday count. The breakdown updates too, showing working weeks, working months, working years, and work hours based on a standard 8-hour day.
