## difference in average revenue between different periods of the same holiday

I don't know how to calculate the 2 columns in red. Since it is not possible to use date dimensions, which dax structure should I use to calculate the percentage difference between these values ​​for the same holiday period that occur at different times of the year?

 Holida Average Revenue Last Average Revenue Diff % 2018 100 30/03 150 31/03 50 2019 200 100 50% 10/04 300 150 11/04 100 50 2020 150 200 -33% 27/04 200 300 28/04 100 100

Original Table:

I have a table with dates from 2017 to 2021 and a column with the revenue per day. I have another column with the holidays, which normally last 3 days, however from year to year there are same holidays that fall on different days. I made an averagex to calculate the average revenue per holiday. Now I would like to calculate a percentage difference measure of the average revenue per holiday period over the years, as in the table in the original question.

I want to assemble on the power bi a segmenter with the name of the holidays and a matrix with the years, the average revenue considering only the selected holidays and the percentage difference compared to the previous holiday (which probably does not fall in the same period of the previous year) .

Segmenter:

Matrix:

 Year Avarege Revenue Diff % 2017 100 2018 200 50% 2019 150 -33%

is very similar to calculating the percentage difference from the previous year, however the days compared are different from year to year, what we have in common is the holiday column

Help plz =D
