Frequently Asked Questions

What's the difference between including and excluding the end date?
Including the end date counts both the start and end dates in the calculation. Excluding it only counts from the start date up to (but not including) the end date. For example, Jan 1 to Jan 3 with end date included = 3 days, without = 2 days.
How are months and years calculated?
Months are calculated based on the actual calendar months between dates, accounting for different month lengths. Years are calculated based on 365.25 days per year to account for leap years.
Can I calculate date ranges for past dates?
Yes! The calculator works for any date range, whether past, present, or future. Perfect for historical analysis and future planning.
What's the maximum date range I can calculate?
The calculator can handle date ranges from a single day to many decades. There's no practical limit for most use cases.
