# Calculate FIXED months between two dates

I'm trying to calculate a count of months between date slicer dates to used it as a denomitar in order to calculate an average based on all periods for all customers.

The idea is to calculate the average of sales between 2 dates for each customer, but globally and not only considering the months I got a sale to a customer. In example, in a 24 months period what's the sales average fot customer X who a only sale him on march and june 2018?

any ideas?

## Re: Calculate FIXED months between two dates

I tried this solution, but the problem was that when I use the result on a table with all my customers this value was reevaluated for each customer with only the dates on which the sales where made and I needed a fixed value.

What I did was to create a new table CALENDAR

Calendar = CALENDAR( DATE(2015;01;01) ; DATE(2020;01;01))

and use these values on the slicer instead of the sales dates. With these changes I was able to calculate a sales frequency for each customer on a fixed period.

thanks!

Seems like you could use DATEDIFF of the MAX and MIN of your slicer.
