We go sequentially through our months, knocking off all the firsts of the month, then the seconds, and so forth. And we don't limit ourselves to 12 months like some other countries do, we have also Octember and Septober and Bleen and so forth - 28 or 30 or even 31 of them all told, I forget exactly. But our months do have only 12 days in them, so that the year comes out evenly at the end. For continuity's sake, we have January 1, just like you do. HTH.
