In Master calendar use

For Rolling 24 months:

If( YourDateFieldHere > monthstart(addmonths(today(),-22)) and YourDateFieldHere <= Today(),1) as [Rolling 24],

For Last Month:

if(InMonth(YourDateFieldHere, today(),-1), 1, 0) as LastMonthFlag,

and in front end use a Set Analysis function

sum or count as per your requirement and({<[Rolling 24],LastMonthFlag={1}>}.......)
