Add 7 Days to a date in Excel (3 Methods)

You can add a certain number of days to an existing date by applying some built-in Excel features and functions. Let’s consider a situation where you are working in an online bookstore and every seven days after, you have to deliver some certain books to some customers. Now you can apply some Excel functions or features to insert those days automatically. Let’s discuss those methods.

1. Using the FILL SERIES Method


FILL SERIES is an amazing method that you can apply to add 7 days to a date. In the following example, we have a dataset containing the columns “Book Name”, “Price”, and “Delivery Date”. We need to add 7 days to a specific date in the Delivery Date column.

3. Using the DATE Function

The DATE function is an effective function to add years, months, or days to a date. We will use this function to add 7 days to a specific date.


Add the first delivery date manually. Now in cell D5, apply the DATE function. Insert the values and the final formula is



  • The YEAR function looks at the date in cell D5 and returns 2020.
  • The MONTH function returns the month value from cell D5.
  • The DAY function returns the day value from cell D4. It then adds 7 days to the given date.

Now press Enter to get the result.
