Knowing the current month of a cell in the visualization, the previous month is the maximum month number available in the filter context provided by ALLSELECTED excluding the current and following months. Same as start of period, for end of period I will use a simple calculation, but this time with LastDate() to find the latest date in the current selection. I use this a lot. We don't use the date table as it would give us 12/31/2019. Depends on the filter context you may get a different result from these functions.
