How do I calculate the number of hotel nights?
Count the date gaps from check-in to check-out. A June 10 arrival and June 13 departure normally means the nights of June 10, 11 and 12: three nights.

Calculate the number of nights between two dates
Use this night calculator for a hotel stay or any dated trip. It counts accommodation nights, calendar dates touched and full days between travel days. The dates stay in this browser and are not uploaded or saved.
This is the first calendar date included in the trip.
The departure date is not counted as a hotel night.
Enter arrival and departure dates to calculate trip days and nights.
Add both dates. For example, arriving June 10 and departing June 13 is three nights across four calendar dates.
What this count does and does not mean
Nights are the date gaps between arrival and departure. Calendar days include both endpoints. “Full days between” excludes the arrival and departure dates; it does not know your flight times, early check-in, late check-out, overnight transport, hotel policy or time zones.
Use the count correctly
How to count hotel nights between two dates.
This hotel night counter uses calendar dates only: the difference between arrival and departure is the usual number of nights, while counting both endpoints gives the inclusive trip days. Confirm check-in, check-out and overnight-transport rules with the actual booking before reserving accommodation.

Arriving on an overnight flight? Use the flight time calculator across time zones to check the destination-local arrival date from your schedule. Keep that separate from the room dates you book: an early arrival does not guarantee early hotel check-in.
Once the room-night count is clear, enter the complete lodging total in the trip cost and travel budget calculator alongside transport, food, activities and a separate buffer.
Is a 4-day trip 3 nights?
Usually, yes. When a trip touches four consecutive calendar dates, check-out is the fourth date but the stay covers the three nights before it.
Does the check-out date count as a night?
Normally no: it is a calendar date, not another hotel night. Confirm whether an overnight flight, early arrival or late departure changes the room nights you need.
