Frequently Asked Questions
Does it include the start date?
This calculator measures the difference between the two selected dates. If you need “inclusive” counting (including both start and end dates), add 1 day to the result.
Why can results differ by 1 day sometimes?
Daylight saving time can affect date calculations in some regions. This calculator normalizes time to reduce that issue.
