Frequently Asked Questions
- Does this calculator account for leap years?
- Yes, the calculation includes leap-year rules to ensure an exact day count between the dates.
- Can I calculate partial days or time differences less than a day?
- No, the tool only calculates full calendar days. Hours or minutes must be converted to complete days before using this calculator.
- What happens if the Start Date is after the End Date?
- The calculator uses the formula End Date minus Start Date, so the Start Date should be earlier than the End Date to get a positive total days value.
