- End Date: Select the later date.
The calculator will instantly show you the total duration in years, months, and days.
Frequently Asked Questions (FAQ)
Q: Is the end date included in the calculation?
A: No. This calculator measures the number of full days *between* the two dates. The end date itself is not counted as part of the duration, which is the standard for most date difference calculations.
Q: Can I use this to find out how many business days are between two dates?
A: This tool calculates the total calendar days. It does not exclude weekends or public holidays. For business day calculations, a more specialized tool would be required.
