How Does the Trip Duration Calculator Work?
The calculator takes the difference between your start and end dates as the trip length in days, with nights always one fewer than days — so July 10 to July 17 is 7 days and 6 nights. The weekday/weekend split is useful for planning around business hours, museum closures, and weekend crowds at your destination.
If you add optional start and end times, the total-hours figure becomes precise to the minute, which helps when comparing car rental periods or calculating time away for work purposes.
Frequently Asked Questions
How are days and nights counted?
Days are the difference between your start and end dates, and nights are one fewer than days. July 10 to July 17 is 7 days and 6 nights. A trip that starts and ends on the same date counts as 1 day and 0 nights.
Why do hotels count nights instead of days?
Hotels charge per night of accommodation, not per calendar day. A trip of 8 days requires 7 hotel nights, so the night count is usually the number that matters for your accommodation budget.
What are the optional time fields for?
Adding a start and end time refines the total-hours figure. Without times, the calculator assumes the trip starts at midnight on the first day and ends at midnight after the last day.
Does the calculator handle leap years?
Yes. All date math uses real calendar dates, so leap days, month lengths, and year boundaries are handled correctly.
