Free time and date tool
Count the calendar days until a future date or since a past date.
Result
Enter values and calculate.
How this tool works
The calculator compares calendar dates at midnight in UTC, so the result is a stable whole-day count even across daylight-saving transitions.
Worked example
If today is March 1 and the target is March 15, there are 14 calendar days until the target.
Frequently asked questions
Does today count as one day?
No. A target date equal to the starting date returns zero days.
Can I use a past target date?
Yes. The result will say how many days ago the target occurred.
Are weekends included?
Yes. This tool counts all calendar days; use the Workdays Calculator to exclude weekends.
