I guess if you take a month as an average of about 27 1/2 days, then a month from January 30th would be February 26th.
But then again, that ignores the idea that a Month from now is just the same date, but in the month ahead.
Which means you can't consider a month away, to simply be the same date as now, plus a month.
Since months have different lengths, it makes it impossible. February in particular.
