In this article, you will find out how to get a next anniversary date. In order to calculate the next anniversary date after certain data, you will have to get familiar with DATEDIF and EDATE functions. The DATEDIF function returns a number of years between two dates, while EDATE function returns a date in a certain number of months. Also, you will see how to get a next anniversary date from today.
Next anniversary date
Let’s first look at DATEDIF function. This function returns a number of years between two dates. The parameters of the functions are Date – a date from which we count years, Date_to – a date to which we count years, so the third parameter is “y”, which tells the function that we want to count years between dates.
The EDATE function returns a date in a selected number of months. Parameters of the function are Date – a date for which we want to add a certain number of months. Months – a number of months that we want to add on a selected date.
Now we can look at the example of finding a next anniversary date. The formula looks like:
Figure 1. Next anniversary date from certain date
The date for which we want to find the anniversary is in column B (“Date”). In column C (“Date from”) we put the date from which we want to find the next anniversary date. As you can see, the formula (DATEDIF(B3,C3,y)+1)*12 will be the number of months for function EDATE, while B3 cell will be the start date. The formula DATEDIF returns number 1 years between 30-Jun-17 and 1-Dec-18. We must add 1 to this number in order to get the next year and multiply by 12 to get the number of total months. So, the result in the cell D3 is 30-Jun-19, which is the first anniversary for the date 30-Jun-17 after 1-Dec-18.
In the second example, we will find the next anniversary from today, so we just don’t need the column C (“Date from”). Instead of this (C3), we will put function TODAY() which returns today date into function DATEDIF.

As you can see the next anniversary from today for date 30-Jun-17 (B3) is 30-Jun-19 in the cell C3.
