576 65536 / 885 = 74; 74x12 = 888. So max 888. Any vehicles above that were not _on_new_vehicle_day_proc'd |

577 eg. aged. |
|
578 So new code updates it for max vehicles. |
|
579 (_vehicles_size / maximum number of times ctr is incremented before reset ) + 1 (to get last vehicles too) |
|
580 max size of _date_fract / 885 (added each tick) is number of times before ctr is reset. |

581 Calculation might look complicated, but compiler just replaces it with 35, so that's ok |
