Completed This Month - Improve my Measure

Is there a better way I could be writing this measure? I’m trying to display a count of tasks completed in the current month. Right now that would be what’s completed in the month of September but as soon as October 1st comes, I would like it to start calculating for completed in the month of October. I have my measure in a state that I will have to update it every month.

DateBetween([Measures].[Issue resolution date],“September 01 2022”,‘today’)
),
[Measures].[Issues resolved])
