Answer: Count no of nights between dates
To count the number of nights stayed at a hotel, follow these steps:
- In a new cell, enter the formula: =DATEDIF(start_date, end_date, "d")
Replace "start_date" with the cell reference of the first date in your row 1, and "end_date" with the cell reference of the last date in your row 1. - Press Enter to calculate the number of days between the start and end dates.
- To convert the number of days to the number of nights, subtract 1 from the result. This is because the check-in day is not counted as a night, but the check-out day is.
- To count the number of nights stayed at the hotel, you can use the COUNTIF function. Enter the formula: =COUNTIF(row_2, "x")
Replace "row_2" with the row number where you have marked "x" for the nights stayed at the hotel. - Press Enter to calculate the number of nights stayed at the hotel.
- To combine the two formulas, enter the formula: =DATEDIF(start_date, end_date, "d")-1-COUNTIF(row_2, "x")
This will give you the number of nights stayed at the hotel between the start and end dates.
