Frequently Asked Questions
Does this calculator account for leap years?
Yes, our calculator uses standard JavaScript Date objects which automatically account for leap years (an extra day in February every 4 years).
Is the end date included in the calculation?
Standard date difference calculations do not include the end date. For example, the difference between Monday and Tuesday is 1 day. If you want an inclusive count, simply add 1 to the final result.
What happens if I enter the end date before the start date?
The calculator will automatically find the absolute difference between the two dates, so the order you enter them doesn't matter.
Can I use this to count down to an event?
Absolutely! Just set the Start Date as today, and the End Date as your upcoming vacation, wedding, or deadline to get an exact countdown in days.
