how can I calculate the same variable period compared to the previous year?
for example, compared to the current month, I would like to have a dashboard that tells me how many leads I have generated compared to the previous year
therefore 1-8 September 2023 compared to 1-8 September 2022
tomorrow it should be updated, however, calculating from 1 to 9 September, so until the end of the month
then it should start again from the following month with the same calculation
