I am trying to find the difference in days between the current date today() and the end of the current year. All the functions I am finding want a table field as an argument. But I am not concerned with my dataset for this purpose.
As an example, today is 02/19/2020. there are 316 days until the end of the year. I want a measure that will show 316 today, 315 tomorrow, etc. Then roll over to 365 on january 1st 2021.
