Don't take my word for a fact, but as a "newbie" so to speak in meditation (not actually new, but now I'm consistent) I can tell that are periods, maybe astrological when it's easier to do a lot of things.
Also, try to remember if you did something specifical in those months, for example fiscal exercise, or something in your diet that you are eating now and not then.
