Frequently asked questions
How do I calculate the number of days between two dates?
Simply enter your start and end dates in the tool above and it instantly calculates the exact number of days — no math needed.
Does the calculator include both the start and end date?
No — the calculator counts the elapsed days between your two dates, so April 1 to April 2 shows 1 day. If you need both the start and end date included (inclusive counting), simply add 1 to the result.
Can I calculate days between dates in different years?
Absolutely. The tool handles any date range across multiple years, accounting for leap years automatically.
What if my end date is before my start date?
No problem — the tool handles reverse date ranges and still shows you the correct number of days with a clear label.
Can I include hours and minutes in the calculation?
Yes — toggle the "Include time of day?" option to add specific hours and minutes to both dates for a more precise result.
What can I use this calculator for?
Common uses include counting down to a wedding, vacation, or event; calculating how long a project took; figuring out contract or lease durations; and tracking age or anniversaries.
