Frequently Asked Questions
Does it count the start or end date?
It measures the span between the two dates. Whether you include both endpoints depends on how you're using the count, so add a day if you need inclusive counting.
Does it account for leap years?
Yes. February gets an extra day in leap years, which is reflected in the day count.
Can the end date be before the start?
You'll get a negative or reversed span — just swap the dates if you need a positive duration.
Important Disclaimer
Counts calendar days between dates, accounting for leap years. How you treat endpoints (inclusive or exclusive) is up to you.
