Frequently Asked Questions
How are weeks, months, and years calculated from days?
Weeks divide the day count by 7. Months and years use average calendar lengths (30.4375 days/month, 365.25 days/year including leap years) since exact month/year lengths vary.
What if the end date is before the start date?
The tool still shows the absolute number of days between them and flags that the end date comes first.
Is this timezone-aware?
Dates are compared at midnight local time on each date, so the result reflects calendar days regardless of timezone.
