Compare sales over past years with dynamic holiday week adjustment

[477885wk]

I want to compare sales over the past few years. I want to show daily sales based on week number. So a line that represents the current year; week 27, week 28(current), week 29. Another line representing the same weeks for 2018. As time passes and I refresh, the weeks change. But here is the tricky part, some holidays do not occur on the same date every year. So when a holiday is occuring, I need to show the corresponding past week. So 2019 line would show holiday -1(week27), holiday (week 28), holiday +1 (week29). And the 2018 line would adjust and show, holiday -1(week26), holiday (week 27), holiday +1 (week28). Or whatever week it occured. It must be matched properly. Also a regular week in 2019 might have been a holiday in 2018. 

Thank you!

@477885wk ,

You need to import a holiday table from website(The table should contains date and day number in a week) and then build a relationship between the holiday table and original table. Then you can create a calculate column/measure to mark the workdays and other days. For more details, you can refer to similar case below:
