Probably “number of users who were active this month” for monthly, versus “number of users who were active the last half year (6 mo)” for halfyear. Both can be updated monthly. A user who was active 3 months ago would be in the second group but not the first.

Hm, that makes sense. Still a little ambiguous, I think.
