Frequently asked questions
How are months and years counted?
The tool counts complete calendar months and years between the dates, then shows the leftover days, using real calendar lengths.
What does "include the end date" do?
When enabled, both the start and end dates count, adding one day to the total — useful for inclusive spans like hotel nights or rental periods.
Can it count business days only?
No, it counts every calendar day between the two dates. For working-day totals you would need to subtract weekends and any holidays separately.
