difference in average revenue between different periods of the same holiday

Anonymous — Thu, 05 Mar 2020 04:24:20 GMT

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

Help me plz. THX!

Original Table:

Date	Holiday	Revenue
01/03/2018		100
02/03/2018	finados	50
03/03/2018	finados	80
04/03/2018	finados	70
05/03/2018		90
06/03/2018		60
...	...	...
27/04/2019	finados	150
28/04/2019	finados	200
29/04/2019	finados	40
30/04/2019		30

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:

Feriados

Natal

Ano Novo

Finados (Selected)

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
