Last day updated in month column

[glamanna]

Hi everybody, I'm new to the DAX language, and I'm trying to create a DAX query to get the last day of each month in my dataset. The problem is that the last day isn't always correct; for example, January ends up on the 30th instead of the 31st. Once I find the last day, I need to assign "1" and "0" to all the other days of the month. I tried using EOMONTH, but it automatically creates the last day even when it's not present in the dataset. Thank you in advance!
